The middle house,planned for its middle.
A Sarawak terrace or link house is long and narrow, shares two walls, and gets almost no daylight or cross-breeze in its middle rooms — so heat and humidity settle in the core and the rear wet kitchen carries the whole cooking load through one external wall. ELS by ALUMAX plans the light path, the air path, the rear wet kitchen and the phasing before any trade starts — so the dark middle becomes usable, the heat has somewhere to go, and you can build it in stages without demolishing your own earlier work.

Cara membuat keputusan sebelum anda membina
A terrace house fails on light, air and sequence decisions made before quotation — not on finish. Use these rules first.
| If | Then |
|---|---|
| The middle rooms are dark all day | Open a light path to the core — a light well, borrowed light or glazed internal doors — before you choose finishes. Downlights do not fix a plan with no daylight. |
| The house feels hot and still in the afternoon | Plan a front-to-back air path and shade the rear / west openings before you size the air-conditioning. Ventilation and shade cut the heat load you then have to cool. |
| The wet kitchen sits at the rear with one external wall | Route the hood duct the shortest way to that wall and specify an aluminium wet-base — never duct into the ceiling void or recirculate. |
| Exhaust routes are limited — shared walls, no side access | Decide the hood, dryer and toilet vent paths on the plan first. Cutting a duct through a party wall afterwards is the expensive fix. |
| You are renovating in phases | Freeze the whole-house scope and M&E once, then build in stages — so wiring, ducts and wet points in phase one already serve phases two and three. |
| Only the rear is wet; the front stays dry | Specify by zone — aluminium at the rear wet run, P6 particleboard or plywood on the dry front — not one material for the whole house. |
Making a long plan livable.
A terrace house is a tube: light and air only enter at the two ends. The first job is to move both into the middle.
One external wall, carrying everything.
At the back of a terrace house, the wet kitchen, drainage and every exhaust compete for one external wall. Coordinating them is the difference between a kitchen that clears and one that sweats.
What the terrace-house specification covers
ELS specifies, coordinates and QCs the whole plan. ALUMAX supplies and installs the cabinetry. Some scope is ALUMAX-direct; some is multi-trade on a project basis.
- Whole-house long-plan layout with a light and air strategy
- Daylight, cross-ventilation and heat-clearance direction for the core
- Moisture-zone material schedule — aluminium wet, P6 / plywood dry
- Rear wet-kitchen cabinet, hood-duct route and drainage intent
- Exhaust-route plan for hood, dryer and toilet vents
- A phasing plan — scope and M&E frozen once, built in stages
- QC hold-points at the end of each phase
- Structural openings and party-wall works — project basis, licensed
- Waterproofing / tanking works — project basis, multi-trade
- Bekalan sistem pengudaraan mekanikal — asas projek
- Plumbing and electrical works — licensed trades
- Harga renovasi akhir — disahkan selepas pengukuran dan sebut harga
What drives a terrace-house quote
The specification fee starts from RM1,500 (excl. SST). The build cost that follows depends on these.
Indicative only — the final quotation follows site measurement, material selection and approved scope. Prices exclude SST.
How to prepare for the Pre-Check
Beberapa perkara yang mempercepatkan spesifikasi dan menjadikan sebut harga lebih tepat.
- A floor plan or rough sketch — mark which walls are shared
- Photos of the dark middle rooms and the rear kitchen
- Which rooms overheat, and at what time of day
- Bagaimana penghisap asap mengalirkan udara sekarang — ke luar, ke ruang siling, atau kitar semula
- Your phase order and rough budget per phase
- Whether you will live in the house during works
- What stays and what is new

Soalan lazim
Why is the middle of my terrace house so dark and hot?
A terrace or link house is long, narrow and shares two side walls, so daylight and breeze only enter at the front and rear. The middle rooms — usually the dining area and stairs — sit furthest from any opening, so they stay dark, and without a front-to-back air path the heat that builds up through the afternoon has nowhere to escape. The fix is planned before finishes: a light path to the core (a light well, borrowed light or glazed internal doors) and a cross-ventilation and shading strategy, so you are not relying on downlights and air-conditioning to paper over the plan.
Can I renovate my terrace house in phases?
Yes — and it is often the sensible way to do it on a budget or while living in the house. The key is to freeze the whole-house scope and the M&E (wiring, plumbing, duct and wet points) once, up front, then build in stages against that single plan. That way the electrical and drainage you install in phase one already serve phases two and three, and a later phase never has to demolish work you have already paid for. Phasing without a frozen plan is how people end up chasing the same wall open twice.
Where should the wet kitchen go in a terrace house?
At the rear, against the external wall — because that is where the hood duct can reach outside air on the shortest run and where drainage can fall to a floor trap. The wet-kitchen base, sink run and anything that stays wet should be specified in ACP or honeycomb aluminium, not board, because board swells in Sarawak's humidity. The dry-side cabinetry away from direct water can use P6 particleboard or plywood. The point is to decide the material by moisture zone, and to place the wet kitchen where its services actually work.
Do I have to knock down walls to get more light?
Not always. Before any structural work, there is usually a lighter path: borrowing light from a brighter room through a glazed internal door or a high-level opening, adding a light well or roof opening where the plan allows, or re-planning which rooms sit in the dark core. Structural openings and any work on a party wall are possible but sit on a project basis and involve a licensed trade, so we scope those separately. ELS plans the light strategy first and only proposes structural work where a lighter option genuinely will not do.
How do you deal with limited exhaust routes on a shared-wall house?
By deciding every exhaust path on the plan before walls and ceilings close. A terrace house often has only one external wall at the rear and no side access, so the hood, the dryer, a toilet fan and any second kitchen exhaust are all competing for a few possible outlets — and they cannot share one hole. We map each duct route to a real outlet up front, size it, and coordinate it with the ceiling and cabinet layout, so nothing gets discovered as impossible after the plaster is up. Cutting a new duct through a party wall afterwards is the expensive, disruptive fix we plan to avoid.
How much does a terrace house renovation specification cost?
The Design + Specification service starts from RM1,500 (excl. SST), depending on scope. Site measurement is from RM300 in Sibu and RM500 outstation, and is creditable on confirmation. That fee covers the plan, the material and services specification and the coordination — the final build cost is confirmed after measurement, material selection and an approved scope, and if you phase the work it is quoted against a single frozen plan. Prices exclude SST.

The weeks ELS saves — by ordering, not waiting.
Freeze the drawings, order every long-lead item the same day, and the 8-week factory lead runs concurrent with demolition and wet works instead of after them.
The binding constraint here: The concurrency itself — and party-wall coordination with the neighbours on both sides.
- The worked baseline above: single-phase M&E, one delivery, one household.
- Party-wall notice and dust / noise control with the attached neighbours.
- Rear wet kitchen sets the waterproofing and drainage sequence.
