Singapore renovation market rates — enter the access code.
Deep-researched per-unit costs for every trade in NC (Singapore)'s two quotes — 505 Yishun command centre ($201,615) and 8 Pollen View carpentry ($120,355) — from published rate cards, public-sector schedules (Sentosa FSOR term contracts), HardwareZone & Reddit threads, and supplier listings. Every NC line item was inspected and benchmarked. ← Back to tracker
Key context: commercial concealed/trunked work realistically runs 1.5–2.5× residential rates (some sources claim 3–4×). Your $45–65 estimates are residential-exposed rates — real, but not achievable for the Yishun commercial spec. The fair commercial targets below already account for that.
| Item | SG Market Range | NC Quoted | Verdict | Notes |
|---|---|---|---|---|
| Lighting point (wiring) | $40–80 resi exposed $70–180 concealed/comm. | $132.25 ×46 | UPPER-BAND | Upper half of the commercial concealed band. Sentosa public term rate was $55 (surface). Your $45–65 estimate matches residential exposed. Fair commercial target: $90–110/point. |
| Light fitting install (downlight/batten) | $15–18 labour-only $55–105 supply+install | $69–$86.25 | FAIR IF SUPPLY INCL. | At market if fitting supply is genuinely included (it is, per the quote wording); would be high if labour-only. Accept. |
| 2×13A double socket (SSO) | $70–130 resi $100–150 commercial top | $166.75 ×56 | ABOVE MARKET | 25–60% above the top published commercial band even allowing trunking. Sentosa term rate: $62/twin point. Your $65 estimate is the residential floor. Fair commercial target: $110–130/point — across 56 points this is a ~$2,000–3,200 lever. |
| Cat6 data point (faceplate, keystone, patch cord) | $80–160 commercial Cat6 $130–200 Cat6A | $149.50 ×111 | AT MARKET | Top of the Cat6 band, mid-Cat6A. Slightly rich if the cable is actually Cat5e — confirm spec. Fair target: $120–140/point; at 111 points even $10/pt = $1,110. |
| 16A 3-pin Ceeform (server rack) | $100–200 heavy-duty socket | $379.50 ×2 | ABOVE MARKET | Above market unless it includes a dedicated radial circuit from the DB — ask NC to confirm; if it does, borderline acceptable. |
| 20A DP isolator (aircon) | $100–500 (aircon installers quote $350–500) | $379.50 ×4 | HIGH-BUT-IN-RANGE | ~2× a typical electrician's rate but inside the range aircon contractors themselves publish for 20A isolators. |
| 100A DB c/w DPM & ELR | ~$2,500–4,500 build-up est. | $4,830 | ~10–40% ABOVE | No published direct comparable; component build-up (board + MCBs + ELR + digital power meter + labour) suggests $2,500–4,500. Not egregious for a one-off custom board but ask for itemisation. |
| LEW T&C + SLD endorsement | $400–1,000 by kVA (public schedule) | $1,150 | AT MARKET (UPPER) | LEW fees are unregulated (EMA). Public-sector schedule: $400 (≤45kVA) to $1,000 (≤300kVA) including submissions + turn-on. Fair at 2026 prices. |
| Sub-main 4×35mm² XLPE + 16mm² earth, ~50m | ~$100–115/m current build-up | $5,347.50 (≈$107/m) | AT MARKET | Sentosa FSOR had 35mm²/4C XLPE at $75/m (2016); with earth cable + trunking share at today's prices, NC's $107/m is fair. Accept. |
NC's Mitsubishi PUMY-CP175YKM (68,200 BTU) is an ~8HP-class mini-VRF — commercial architecture, priced fundamentally differently from residential multi-splits. The changeover panels are the negotiation targets here, not the VRF itself.
| Item | SG Market Range | NC Quoted | Verdict | Notes |
|---|---|---|---|---|
| Residential System 1 | $1,000–2,000 installed | — | REFERENCE | Mitsubishi 9k BTU ~$1,050; Daikin 12k ~$1,187 (2026). Mid-tier brands ~$1,150, premium ~$1,650. |
| Residential System 3 | $2,600–4,000 installed | — | REFERENCE | Mid-tier ~$2,600, premium (Daikin/ME/Panasonic) ~$3,200–4,000. |
| Residential System 4 | $3,400–7,800 installed | — | REFERENCE | Mid-tier ~$3,400, premium ~$4,200–5,000, high-spec to $7,800. Install-only component $900–1,600 (~$400–450/indoor unit). Reusing piping saves $700–1,200. |
| Commercial VRF/VRV (1 outdoor + 3–8 indoors) | $15,000–45,000+ installed | $20,930 | FAIR | Lower-middle of the SG VRF band with full new piping, Class O insulation, cable tray, vacuum + T&C included. Works out to ~$2,750/HP or $307 per 1,000 BTU — the normal 1.5–2× VRF premium over unitary splits. Negotiation headroom only ~5–15%. |
| Change-over panel, 4-FCU (control room) | ~$2,500–5,500 est. installed | $6,210 | HIGH SIDE | No published SG rates (quote-only market); controller hardware itself is <$800 — the cost is custom panel fabrication + EW-licensed wiring. Ask for itemisation or a 20–30% reduction. |
| Change-over panel, 2-FCU (server room) | ~$1,500–3,500 est. installed | $4,025 | HIGH | Simplest configuration (2-unit rotation + trip status). 15–60% above estimate — the strongest aircon negotiation target. |
| Install-only / relocation labour | $120–600/unit by type | — | REFERENCE | Wall-mount $120–400; cassette $350–600; consistent with the $400–800/unit you paid in 2017. |
| BTU sizing rule | 55–60 BTU/sqft standard; 70–80 west-facing | — | RULE OF THUMB | 1HP ≈ 9,000–10,000 BTU. $/1,000 BTU installed: residential $110–200; commercial cassette/package $90–175; VRF $250–350. |
Two price universes exist: specialist direct contractors ($3.30–6/sqft) and installed/finished fit-out bands ($80–200/m²). The Sentosa FSOR public term-contract build-up (~$100–107/m² double-sided insulated) is the most defensible neutral benchmark. Key finding: NC bills the 4.5m height premium twice — once in the partition rate, once as a separate steel line.
| Item | SG Market Range | NC Quoted | Verdict | Notes |
|---|---|---|---|---|
| Double-sided gypsum partition, standard height | $35–65/m² direct $80–130/m² installed guide | — | REFERENCE | $3.30–3.50/sqft from specialist direct contractors; your 2017 CTD anchor ($48.44/m²) still matches today's direct floor. Rockwool adds $10–30/m². |
| Double-sided gypsum, 4.5m high, 50mm rockwool | ~$100–107/m² FSOR build-up | $103.50/m² ×32m² | FAIR… BUT | Rate itself matches the FSOR build-up — but height is partly double-recovered because the steel reinforcement is a separate $5,175 line. Negotiate the pair as one: $85–95/m² with steel retained, or $103.50 with the steel line absorbed. |
| Steel stiffener posts (>3m partitions) | $54–117/m by section weight ($8.10/kg FSOR) | $115/m ×45m | FAIR IF HEAVY SECTION | Fair only if SHS 100×100×5 or heavier; a light 100×50×3 section justifies just $55–75/m. Demand the section size and weight, and verify 45m of posts is geometrically real for this wall run. |
| Brickwall 100mm, plastered, internal | $100–160/m² | — | REFERENCE | FSOR 2024–26 build-up: brick $67.85 + plaster $28.40/side. Your Pollen door seal-up ($675/lot) prices against this. |
| Brickwall 150mm, plastered + waterproofed, curved external | $130–180/m² straight ~$180–210/m² with WP + curve | $230/m² ×34m² | ~10–25% ABOVE | Justified build-up tops out ~$210/m² even with the waterproofing and curve premium. Push toward $190–210/m² (~$700–1,400 saving). |
| Plywood partition 12mm w/ steel stiffener (video wall) | $100–146/m² build-up; timber partitions $150–300/m² | $155.25/m² | FAIR | Bottom of the timber-partition band; sensible for a rigid video-wall backing. Not worth contesting. |
Labour costs have inflated hard — flooring/masonry labour is up ~18% since 2024 alone, and your 2017 Tee Up anchors need a 1.5–2× uplift to compare against today's market. Commercial rates run ~10–20% above HDB benchmarks; landed carries ~$0.50/sqft over HDB.
| Item | SG Market Range | NC Quoted | Verdict | Notes |
|---|---|---|---|---|
| Tiling — laying labour only | $6–8/sqft (600×600) $8–11/sqft large-format | — | REFERENCE | HDB $6.00 / landed $6.50 / condo $7.00 for standard sizes; 1200×1200 up to $11. Wall tiling $7–8; skirting $6–8/rft. |
| Tiling — supply + install | $10–12/sqft ceramic/porcelain | — | REFERENCE | Tile material alone: ceramic $2–3, homogeneous $3.50–4.50 (Hafary ~$6), marble-look/premium from $10/sqft. Cement screed under tiles $2.50–6/sqft. |
| Vinyl (click LVT ~5mm), supply + install | $4.50–7/sqft mid-tier ($2.50–4.50 entry, $7–12 premium) | — | REFERENCE | Install-only: $2–4/sqft. Your 2017 $3.65/sqft is now entry-tier only (+40–90% inflation over 9 years). |
| Laminate (~8mm click), supply + install | $6–8/sqft (band $5–11) | — | REFERENCE | ~2–2.5× your 2017 anchor of $2.80/sqft. |
| Carpet tiles, commercial 500×500 solution-dyed | $4.50–10/sqft supply+install (labour-only $1.50–3) | $61.88/m² = $5.75/sqft ×164m² | FAIR-TO-COMPETITIVE | Lower-middle of the market band for solution-dyed BCF loop pile. Solution-dyed nylon equivalents run $7–15/sqft. Market-correct — accept. |
| Broadloom carpet | $5–12+/sqft supply+install | — | REFERENCE | Higher waste and labour than tiles; tiles usually win commercially. |
| Load-bearing (walkable) glass floor | ~S$150–400+/sqft supply+install | — | REFERENCE | No SG contractor publishes rates (quote-only). International structural laminated glass flooring runs US$100–300/sqft + framing; converted ~S$130–390. Below ~S$100/sqft is a red flag (likely non-structural). Typical minimum project sums $5k–20k. |
| Self-levelling screed 3–4mm | $21.50–43/m² ($2–4/sqft) | $23/m² ×164m² | BOTTOM OF BAND | Competitive. Confirm it excludes deeper patching (thicker builds price as cement screed at ~2× this). Accept. |
Supply + install pricing, covering both the Yishun commercial doors and the Pollen residential context. NC's double-leaf timber door is the standout overcharge in this trade.
| Item | SG Market Range | NC Quoted | Verdict | Notes |
|---|---|---|---|---|
| Fire-rated door, single leaf (½-hr) | $800–1,400 | — | REFERENCE | Incl. SCDF permit, SS lock, closer from most suppliers. 1-hr rating: $1,200–1,700. Metal/commercial FR: $1,800–2,500. |
| Fire-rated door, double leaf (4×7ft) | $1,550–2,000 | — | REFERENCE | Published double-leaf FR anchors: $1,588–1,699 residential suppliers. |
| Solid timber swing door, single | $400–900 | — | REFERENCE | Labour-only install $150–300/door. Bedroom solid laminated from $250. |
| Solid timber swing door, double leaf 1600×2100 (commercial) | $1,500–2,200 fair commercial | $3,150 | HIGH ~40–75% | Oversized custom leaf + site painting explains part, not all. Residential double-leaf solid doors are $650–1,500. Counter at $1,800–2,200. |
| Glass door w/ aluminium frame, single leaf | $980–1,800 tempered retail $1,700–2,100 laminated fair value | $2,137.50/leaf ×5 | TOP-OF-MARKET | 11.52mm laminated + 1.2m SS handle is above the standard 8–10mm tempered retail spec (laminated adds ~20–35%). ~5–20% over fair — a modest lever at 5 doors ($700–2,200 total). |
| Frameless tempered glass door (floor spring) | $1,000–1,600/door ($45–65/sqft) | — | REFERENCE | Consistent with your 2017 anchor ($24–31/sqft) plus 9 years of inflation. Double (pair): $2,300–2,700. |
| Concealed/hidden flush door (in partition) | $1,288–1,488 complete kits premium imports $3–5k+ | $1,552.50 ×2 (extra-over) | ACCEPTABLE | Fair-to-slightly-high (~5–15%) vs local complete concealed-door kits. Not a priority fight. |
| Sliding doors | Timber $630–1,200 Glass soft-close $880–2,000 Large multi-panel $2,000–3,800 | — | REFERENCE | For the Pollen residential context if sliding doors get added as variation orders. |
| Residential doors (Pollen context) | Main $477–1,949; bedroom $250–880; landed custom main $1,500–4,000+ | — | REFERENCE | Fire-rated HDB main from $699. Bedroom install-only $200–600. |
NC's ceiling pricing is "barbell" shaped: painting, access panels and demolition are below market (accept them), the L-box is fair, and the $90/m² false ceiling — the largest single line at ~$14.8k — carries the margin.
| Item | SG Market Range | NC Quoted | Verdict | Notes |
|---|---|---|---|---|
| Gypsum false ceiling (suspended) | $40–48/m² direct trade $65–97/m² commercial/ID band | $90/m² ×164m² | UPPER-MID | Inside the published commercial band but well above direct-contractor rates (a real HardwareZone quote ran $4.03/sqft = $43/m²). With 164m² of volume, push toward $70–80/m² — worth $1,600–3,300. |
| L-box / bulkhead | $9.75–16/ft run ($32–52/m) | $39.38/m ($12/ft) | FAIR | Mid-market, inside the 2026 $12–16/ft band. Not worth fighting. |
| Ceiling access panel 600×600 | $80–150/unit (450×450 anchors) | $56.25 ×4 | BELOW MARKET | Cheaper than both published anchors despite the larger size. Accept, don't touch. |
| Mineral fibre / acoustic grid ceiling | $9–18/sqft acoustic spec | — | REFERENCE | Plain 2×2 T-grid mineral fibre is usually cheaper than gypsum — a viable value-engineering alternative for back-of-house areas, though no citable bare-grid 2025-26 rate was found. |
| Ceiling painting | $21.50–43/m² commercial | $6.75/m² | EXCELLENT | Roughly a third of the lowest published rate. Accept. (Matches the Sentosa FSOR paint rate almost exactly.) |
| Ceiling demolition/strip-out | $30–54/m² reinstatement bands; lump $900–2,500 typical | $2,600 lump (162m² = $16/m²) | GOOD | Half the low end of published bands. Accept. |
Your 2017 anchor of $11.40/sqft (12mm frameless tempered, confirmed 6×) has moved to roughly $15–25/sqft today. Laminated glass adds ~30–60% over tempered. NC's dead-flat ~$75/sqft across three differently-sized framed panels is the biggest glassworks red flag — pure area pricing with no size economics.
| Item | SG Market Range | NC Quoted | Verdict | Notes |
|---|---|---|---|---|
| Tempered glass 10–12mm, fixed panel, supply+install | $15–25/sqft project scale ($30–50 small one-off jobs) | — | REFERENCE | 2017's $11.40/sqft + 40–100% inflation over 9 years. Glass partitions: $7.50–32.50/sqft across published guides. |
| Laminated glass ~11.52–12.7mm (tempered + PVB) | $20–35/sqft standard $40–65/sqft tempered-laminated retail | — | REFERENCE | The laminated premium over plain tempered is +$5–15/sqft (+30–60%). 12.76mm (6+0.76PVB+6) is the standard high-rise/commercial spec. |
| Fixed laminated panel w/ powder-coated alu frame + steel support | Fair build-up: $35–55/sqft (generous retail ceiling ~$60–65) | ~$75/sqft (3 panels: $6,750 / $2,531 / $3,712) | HIGH 25–70% | Build-up: glass $18–28 + labour $6–10 + alu framing $7–11 + steel posts $4–9/sqft. Framing + steel justify ~$12–20/sqft, not ~$40. Counter at $55–60/sqft — worth ~$2,000–3,500 across the three Yishun panels. |
| Powder-coated aluminium framing | $15–25/ft run of perimeter | — | REFERENCE | Complete framed glass partition systems: $120–180/ft run or ~$15–35/sqft at project scale. |
| Glass balustrade (laminated) | $30–55/sqft; ~$110–275/ft run | — | REFERENCE | Tempered version $22–40/sqft; frameless systems $35–65/sqft. |
| Mirror, supply+install w/ backing | $18–25/sqft (vanity $12–18 + min. charge) | Pollen: custom mirror (unpriced) | BENCHMARK WHEN PRICED | Two real 100+ sqft mirror walls priced at ~$21/sqft installed including ply backing. Use this when NC prices Vanessa's room mirror. |
How carpentry is quantified in Singapore: cabinets, wardrobes, consoles and desks are priced per foot run (pfr) — one linear foot along the length at an assumed standard depth/height (wardrobe depth 600mm, kitchen depth 2ft, "full height" = 2500mm; kitchens count top and bottom rows as separate foot runs). Flat elevation work (feature walls, cladding, headboards, platforms) is priced per sqft (psf). Countertops are a separate pfr line by stone type. Base spec = plywood carcass + laminate + soft-close; veneer ≈1.3×, spray paint ≈1.45×, marine ply ≈+50%. NC's Pollen rates overall run ~30–60% above direct-carpenter rate cards — a normal ID-firm premium — but several specific lines break well beyond that.
| Item | SG Market Range | NC Quoted (Pollen) | Verdict | Notes |
|---|---|---|---|---|
| Full-height wardrobe (casement), pfr | $210–400/ft direct (ID mid-tier $400–550) | $363/ft | TOP-OF-MID | Direct carpenters: Uncle Carpenter from $210, Tan $220, S3 $240, Jia Soon/JS $240–400. Fair for landed/premium spec. |
| Full-height shoe cabinet, pfr | $200–380/ft | $495/ft ($4,207.50 / 8.5ft) | HIGH 30–100% | 30–100% above every published full-height shoe rate. Outdoor-rated marine ply justifies +50% on a ~$240 base = ~$360/ft, still below $495. Counter at $360–390/ft. |
| Half-height cabinet, pfr | $130–220/ft | $165/ft | FAIR | Mid-band. Accept. |
| Storage bedhead cabinet, pfr | $120–260/ft (headboard w/ LED $120; storage bedframe $260) | $363/ft | HIGH | Priced at full-wardrobe rate. Counter at $260–300/ft. |
| TV console, pfr | $110–280/ft floor; $130–280 suspended | $198/ft floor; $165/ft susp. | FAIR | Mid-band both. Accept. |
| Feature wall / cladding, laminate, psf | $15–40/sqft | $19.80 & $27.50/sqft | FAIR | Both tiers inside the band (fluted MDF laminate $15–35 installed). Accept. |
| Feature wall, veneer, psf | $40–80/sqft (solid-wood-equivalent band) | $49.50 & $71.50/sqft | $49.50 OK / $71.50 HIGH | Veneer ≈1.3–2× laminate. $71.50 is top-of-market — and NC itself charges $49.50 for the same finish category elsewhere in the same quote. Push A8 down to $49.50/sqft (worth ~$2,860). |
| Upholstered bedhead wall, psf | between laminate and veneer bands | $33/sqft | FAIR | No direct rate card exists; consistent with fabric-panel norms. |
| Study desk, pfr | $80–260/ft (highest published) | $401.50/ft ($1,606 / 4ft) | ~2× OVERPRICED | Only defensible if it bundles overhead cabinets/pedestals into a blended pfr — check the drawing for double-counting, then counter at ~$200–260/ft. |
| Loft bed w/ steel support | platforms $20–35/sqft; complex integrated $2,000–5,000/set | $2,365 (40sqft ≈ $59/sqft) | FAIR-TO-HIGH | Steel-frame elevated loft is structurally beyond a floor platform; sits inside the complex-build band. Storage staircase $275/ft ≈ tall-storage pfr — fair for drawer-staircase. |
| Bar counter, 2-tier L-shape marine ply, pfr | $250–450/ft laminate island; marine +50% | $449.63/ft | FAIR | Top of the island band, justified by marine ply + s/s foot rail. The separate marine-ply backing structure at $605/ft is ~35% above the adjusted ceiling — HIGH, gold laminate only partially explains. |
| Dekton / sintered stone countertop, pfr | $120–220/ft sintered Dekton premium ~$250/ft | $589.60/ft ($14,150.40 / 24ft) | 2.4–4.9× — CHALLENGE HARD | The single biggest outlier across both quotes. No Singapore source supports >$250/ft even for top-grade Dekton with premium edge. Only mitigant: thick mitred aprons/waterfall ends can double effective footage — make NC show exactly how 24ft was measured, then counter at $250–300/ft (≈$6,000–7,200) or carve this line out and re-tender to a stone fabricator directly. Potential saving: ~$7,000. |
| Timber cove light box | $20–40/sqft carpentry analogue | $27.50/sqft | FAIR (CHECK BASIS) | Rate is fine; cove/L-box is conventionally quoted per foot run — psf can inflate quantity on tall boxes. Verify the 85sqft measurement. |
My recommended fair rates for negotiating with NC Singapore, with justification. These already price in the commercial premium (Yishun) and ID-firm premium (Pollen) — they are what a well-informed client should pay, not bare direct-trade floors.
| Item | Advised Fair Rate | NC Quoted | Justification |
|---|---|---|---|
| Lighting point (commercial, trunked) | $90–110/pt | $132.25 | Upper half of the $70–180 commercial concealed band is unjustified at 46-point volume; your $45–65 estimate is residential and not attainable here. |
| 2×13A double socket (commercial) | $110–130/pt | $166.75 | Top published commercial band is $100–150; NC is 25–60% over. Biggest electrical lever: 56 points × ~$40 = ~$2,200. |
| Cat6 data point (commercial) | $120–140/pt | $149.50 | NC is at the top of the Cat6 band ($100–160). At 111 points, even $10–25/pt matters ($1,100–2,800). Confirm cable is genuinely Cat6, not Cat5e. |
| VRF system ~68k BTU + 5 FCU | $18,000–21,000 | $20,930 | Fair within the $15k–45k SG VRF band with full new piping; only 5–15% headroom. Not a priority fight. |
| Change-over panels (4-FCU / 2-FCU) | $4,000–5,500 / $2,500–3,500 | $6,210 / $4,025 | Controller hardware costs under $800; the rest is panel fabrication + licensed wiring. Both above reasoned build-up; combined lever ~$2,500–4,200. |
| Gypsum partition 4.5m + steel package | $85–95/m² (steel kept) or $103.50 (steel absorbed) | $103.50/m² + $115/m steel | The partition rate matches the public FSOR build-up only if height isn't also billed separately — but it is ($5,175 of steel). One or the other, not both. |
| Brickwall 150mm plastered + WP, curved | $190–210/m² | $230/m² | FSOR-derived build-up with waterproofing and a 25% curve premium tops out ~$210. 10–25% over. |
| Gypsum false ceiling (commercial, 164m²) | $70–80/m² | $90/m² | Inside the $65–97 commercial band but the largest ceiling line; 164m² volume warrants a bulk rate. Direct-trade evidence at $40–48/m² is your anchor. Worth $1,600–3,300. |
| Carpet tiles / self-levelling screed / L-box / access panels / painting / demolition | ACCEPT AS QUOTED | various | All at or below market ($5.75/sqft carpet, $23/m² screed, $12/ft L-box, $56.25 panels, $6.75/m² paint, $16/m² demo). Conceding these visibly strengthens your position on the real levers. |
| Double-leaf solid timber door 1600×2100 | $1,800–2,200 | $3,150 | 40–75% above fair commercial benchmark; oversized custom leaf + site paint justifies the top of my range, not beyond it. |
| Framed laminated-glass door (per leaf) | $1,700–2,100 | $2,137.50 | Laminated glass + 1.2m SS handle puts fair value near the top of retail; NC is only 5–20% over — modest lever across 5 doors. |
| Framed laminated fixed glass panels | $55–60/sqft | ~$75/sqft | Component build-up (glass $18–28, labour $6–10, framing $7–11, steel $4–9) lands $35–55; $55–60 concedes a retail margin. Worth $2,000–3,500 across three Yishun panels. |
| Full-height wardrobe (Pollen) | $300–363/ft | $363/ft | Top of mid-market; acceptable for landed premium spec. Marginal push only. |
| Shoe cabinet, outdoor marine ply (Pollen) | $360–390/ft | $495/ft | Marine ply justifies +50% on a $240 base = $360; $495 exceeds even that. ~$900–1,150 lever. |
| Storage bedhead cabinet (Pollen) | $260–300/ft | $363/ft | Priced at full-wardrobe rate; bedframe/headboard comps run $120–260/ft. ~$880–1,440 lever across 14ft. |
| Study desk (Pollen) | $200–260/ft | $401.50/ft | ~2× the highest published desk rate ($260); first verify the drawing isn't bundling overhead cabinets into the blended rate. |
| Veneer cladding, façade wall A8 (Pollen) | $49.50/sqft | $71.50/sqft | NC itself charges $49.50 for the same finish category on the AC wall (A9) in the same quote. Internal-consistency argument — hardest to refuse. Worth ~$2,860. |
| Dekton countertop (Pollen) | $250–300/ft | $589.60/ft | Biggest single lever across both quotes (~$7,000). SquareRooms puts Dekton at $250/pfr premium tier; sintered generally $120–220. Demand the footage measurement method, then counter or re-tender to a stone fabricator. |
| Supervision/documentation ($8,000 + $4,500 + $575, Yishun) | $3,000–5,000 total | $13,075 | Your own margin note ("reduce to $3,000 inclusive") is backed by history: CTD bundled all supervision/design FOC on every job 2017–2021. The second $4,500 supervision line under AC is double-charging the same function. |
Combined realistic negotiation value if the above targets land: ~$18,000–28,000 off Yishun ($201,615) and ~$12,000–16,000 off Pollen ($120,355) — without touching the lines that are already fairly priced, which you should concede early and visibly.
