Design options 61 sets of design options — 36 with named options · 25 visual references These are concept design options — looking at one chooses nothing and prices nothing. Quoting one needs your choice, the room it is for, and an ELS check against the specification. Cost lines are relative and typical for the illustrated specification. Relative cost names the direct cost drivers, consequential work names what else changes, and watch out names the checks required. Exceptions and site conditions can change any of them. A relative direction, not an amount. Nothing here is a price; the figure belongs to whoever supplies the item and is set after measurement.

Design intent — subject to feasibility and site measurement; any variation is agreed with you before work continues.
Concept renders — a design render, not a photo. Shown as design options for one decision.
Supply and installation confirmed with your specification. How this is priced is confirmed after measurement, by whoever supplies it.
Wall split unit Ceiling cassette Concealed ducted / zoned Show the trade-offs Wall split unit
Best for The pragmatic default — simplest to install, service and replace.
Watch out The wall unit is visible and dictates where furniture can sit; it dates the room faster than the joinery. Cost and scope2
Relative cost The least expensive of the three.
Consequential work Fixes wall position, drainage fall and the pipe route to the condenser — decide before the wall finish. Ceiling cassette
Best for Even distribution across a square room from a single central point.
Watch out Needs real ceiling void; it commits the ceiling design and is disruptive to retrofit. Cost and scope2
Relative cost Higher than a split.
Consequential work Ceiling height, void depth and drainage fall must be settled before the ceiling is closed. Concealed ducted / zoned
Best for Concealing the system entirely across several rooms from one plant location.
Watch out The most demanding of the three: duct routing, void depth and return-air paths all have to work, and service access must be planned. Cost and scope2
Relative cost The highest.
Consequential work Drives the ceiling design across multiple rooms and must be coordinated with lighting and any structural downstand. Also part of this decision, not pictured: Fans only / no AC
SPC (stone-plastic composite) Porcelain tile Engineered timber Show the trade-offs SPC (stone-plastic composite)
Best for Rooms that need timber's look with real moisture tolerance.
Watch out The wear layer is thin: deep scratches cannot be sanded out, only replaced. A poorly levelled slab telegraphs through. Cost and scope2
Relative cost Lower than tile or timber once laid.
Consequential work Needs a level, dry slab; screeding and moisture readings belong in the programme before delivery. Porcelain tile
Best for Wet and high-traffic areas.
Watch out Hard and cold underfoot, and grout is the maintenance line — colour choice matters more than most clients expect. Cost and scope2
Relative cost Varies widely by format; large formats cost more to lay than to buy.
Consequential work Sets floor level and threshold details against adjoining rooms; falls and drainage must be resolved first. Engineered timber
Best for Bedrooms and upper floors where warmth matters and water exposure is genuinely low.
Watch out Real timber moves with humidity; in an unconditioned Sarawak room expect movement at the joints. Not for a ground floor with flood risk. Cost and scope2
Relative cost The highest of the three, and the most sensitive to species.
Consequential work Requires acclimatisation time on site and a decided expansion gap at every perimeter and threshold. Shown on a bare wall rather than a styled feature wall, so the sheen is what you compare.
Acrylic matte Washable eggshell Satin acrylic Semi-gloss enamel Mineral limewash Show the trade-offs Acrylic matte
Best for Walls where a flat, non-reflective surface hides minor unevenness.
Watch out The least scrubbable — marks in a circulation zone will show and touch-up flashes. Cost and scope2
Relative cost The reference point.
Consequential work Best kept away from wet areas and high-touch surfaces. Washable eggshell
Best for The pragmatic middle for family rooms — cleanable without a shine.
Watch out Not fully scrubbable despite the name; check the manufacturer's actual claim. Cost and scope2
Relative cost Moderate.
Consequential work Confirm the cleaning expectation with the client so the finish is not blamed later. Satin acrylic
Best for A durable, wipeable general-purpose finish for busy rooms.
Watch out The sheen shows wall unevenness that a matte finish would hide. Cost and scope2
Relative cost Moderate.
Consequential work Substrate preparation matters more than with a matte finish. Semi-gloss enamel
Best for Trim, doors and anywhere that takes hands and cleaning.
Watch out Unforgiving of surface defects and brush marks; the higher the sheen, the more it shows. Cost and scope2
Relative cost Higher.
Consequential work Preparation standard must be agreed — this finish exposes it. Mineral limewash
Best for A soft, breathable finish with visible depth and movement.
Watch out It is a texture, not just a colour — application skill decides the result, and touch-up is difficult. Cost and scope2
Relative cost Higher, and the cost is in application.
Consequential work Requires a competent applicator and a sample panel signed off before the room is done. Fabric panels PET felt Show the trade-offs Fabric panels
Best for The most absorption per area — rooms with a real echo problem.
Watch out Fabric collects dust and, in a humid room, needs to be a material that tolerates it. Cost and scope2
Relative cost Moderate.
Consequential work Panel positions should follow the reflection points, not just the composition. PET felt
Best for A durable, wipeable absorber that can also be a graphic element.
Watch out Absorbs a narrower range than fabric over a cavity — good for speech, less for low frequencies. Cost and scope2
Relative cost Moderate.
Consequential work Fixing and joint detail are visible; they need drawing. One option isn't shown yet — coming soon.
Repair Upgrade Show the trade-offs Repair
Best for Sound construction with surface damage — the fault is cosmetic, not structural.
Watch out Repair reveals its own scope once opened; budget for a finding, not just the visible fault. Cost and scope2
Relative cost Lower than replacement, but less predictable.
Consequential work Needs a hold point after opening up, so the decision can change on evidence. Upgrade
Best for Improving something that works — better performance without full replacement.
Watch out The temptation is to upgrade what is visible rather than what fails; check the reasoning. Cost and scope2
Relative cost Between repair and replace.
Consequential work Confirm the upgrade is compatible with what is retained around it. 2 options aren't shown yet — coming soon.
