When people say "feature wall" in a Singapore reno, they usually mean a full-height TV background — built-in cabinetry behind and around the screen, often with drawers below, concealed wiring, and sometimes lighting or curved edges. It is not just a panel stuck on the wall; it is custom carpentry measured to your room.
In my recent remodel, the TV feature wall was one of the most detailed pieces we designed — storage for dumbbells, hidden sockets, drawer layouts, the works. That complexity shows up in the quote, but the base carpentry itself is still priced simply: by area, then by material grade.
Start from a typical HDB height
Most HDB flats sit around 2.6 m floor-to-ceiling — that's why the calculator defaults height to 2,600 mm. Guides from Qanvast put newer HDB / BTO units near that mark, with older flats sometimes a little lower. If you add a false ceiling later, HDB renovation guidelines require at least 2.4 m clearance from finished floor level.
My own Jishang quote measured the TV background at 2685 × 2940 mm — taller than a stock HDB ceiling because the space (and design) allowed it. Always tape-measure your wall; don't assume 2.6 m.
How the base price is calculated
From a real Jishang Furniture quotation, the TV background (电视背景) is charged per square metre. Material rate is not fixed — it ranges roughly RMB 799 to RMB 1,899 /m² depending on the board you pick. We chose an upgraded mid tier at RMB 1,199/m² — mainly because we do not like finishes that show fingerprint stains and marks easily. The cheaper board can look fine, but if you also hate smudges on a big TV wall you touch every day, use this upgraded rate as your planning reference rather than the basic RMB 799. Quantity is width × height (mm → metres):
Base cost = width (m) × height (m) × material rate (RMB/m²)
On that quote sheet, 2685 × 2940 mm at RMB 1,199/m² came to about RMB 9,465 for the base board alone (7.89 m²). Depth (420 mm) describes how far the unit projects into the room — it does not multiply into the area formula.
Optional curved edges (r35)
Soft vertical edges are a separate line item — r35 圆弧 on the sheet — billed per metre of exposed edge. If one side of the feature wall sits against a room wall, you only need one curved edge. If you put the unit in the middle with both sides open, both vertical edges can be curved.
My quote was the one-side case: RMB 580/m × wall height (2.94 m → RMB 1,705).
Curve cost = height (m) × sides (1 or 2) × RMB 580/m
Use the calculator toggle, then pick one side or both — the 3D preview and total update together.
