Kampung & Wooden House Renovation
Repair, Half-Brick or Timber-to-Brick (2026)

What makes a wooden house different

A traditional kampung house is a timber frame standing on posts, with a raised floor, a pitched roof with deep overhangs, and plenty of openings for air. It stays dry and cool not because of membranes but because of its design. ClickBina's old house waterproofing guide puts it plainly: timber houses depend on roof integrity, generous overhangs and the ventilation under a raised floor, and the right work is fixing the roof and keeping air moving, never sealing the structure in plastic.

That changes how you renovate. Modern habits such as cement render over timber, closing in the space under the house, or pouring a concrete floor around the posts can trap moisture and speed up rot and termite attack. The first question is always what state the structure is in.

Start with a structural and condition survey

• Posts and stumps: rot or termite damage at the base, where timber meets the ground or a concrete pad.
• Floor joists and bearers: soft spots, sagging floors, bouncing boards.
• Walls and frame: leaning, gaps opening at joints, doors and windows that no longer close.
• Roof: leaks, rusted zinc or broken tiles, rotten rafters and battens.
• Termites: mud tubes, hollow-sounding timber, wings after rain.
• Wiring: old surface wiring on timber, overloaded circuits, no earth leakage protection.
• Wet areas: kitchen and bathroom floors where water has soaked into the timber.

A contractor can walk you through most of this, but where posts, joists or the frame are moving, ask a Professional Engineer to confirm what can be kept before any design is fixed.

Three routes: repair, half-brick or full rebuild

The half-brick house is common across Malaysia for good reason: the wet, heavy-use rooms go into masonry, while the cooler timber rooms upstairs are kept. It is also the route where good detailing matters most, because the join between the old timber and the new brick is where leaks and termites find their way in.

Repairing and keeping the timber house

Rotten post bases are commonly cut back to sound timber and set on new concrete stumps, and damaged joists and floor boards replaced with treated timber of a matching size. The roof is often the biggest single item: replacing rusted zinc or broken tiles, and repairing or replacing rotten rafters and battens, keeps the whole house dry. Keep the space under the house open and ventilated, and keep soil, plants and stored items away from the posts.

Termites need treating before the repairs, not after, or new timber is simply fresh food. Our termite control guide explains soil treatment and baiting systems for existing homes.

Wiring and fire safety

Old wiring clipped directly onto timber walls, joined with tape and running more appliances than it was designed for, is the most serious risk in an old wooden house. A renovation is the right time for a competent electrical contractor to inspect it, and in most old kampung houses a full rewire in conduit, with a new distribution board and earth leakage protection, is the sensible outcome. On ClickBina's rewiring guide a terrace house is RM8,000 – RM15,000 (indicative 2026, Klang Valley), a useful yardstick.

Kitchens and bathrooms: move them into masonry

Water is the enemy of a timber floor. Bathrooms and wet kitchens built on timber boards leak into the joists every day, and the rot is often hidden until the floor gives way. Most renovations move the wet areas into a brick annex or the new brick ground floor, on a concrete slab with proper waterproofing and falls to the floor trap. Keep the plumbing out of the timber frame where you can.

Full conversion from timber to brick

Replacing a timber house with a brick one is new construction. It needs foundations designed for a much heavier building, a reinforced concrete frame or load-bearing walls, a new roof structure, and all the services. Building brick walls around or under an existing timber frame without a structural design is risky, because the timber and the masonry move differently and the old posts were never meant to carry brick.

Treat the ground under any new brick section against termites before the slab is poured; our pre-construction anti-termite guide explains how it is done.

Land, plans and approvals

Check the land title and whether the existing house has approved plans before you design anything. Structural work, extensions and a rebuild need council approval, and according to ClickBina's renovation permit guide a Professional Engineer's structural drawings are part of the submission. Rules and fees differ between local authorities, so confirm with yours early, especially for houses outside the main Klang Valley councils.

What a wooden house renovation costs

There is no single rate for a kampung house, because the work depends on what the survey finds. These indicative Klang Valley figures from ClickBina's published guides (2026) show the scale of the main items.

Council fees, replacement timber, posts and joists, and finishes are priced after the survey. A full rebuild is priced like new construction, not as a renovation.

Mistakes that shorten a wooden house's life

• Sealing timber in cement render or plastic sheeting, which traps moisture.
• Closing in the space under the house without ventilation or a proper slab.
• Pouring concrete around timber posts, creating a wet pocket where rot starts.
• Repairing before treating termites, so the new timber is attacked.
• Adding brick walls onto the timber frame without a structural design.
• Leaving bathrooms on timber floors and hoping the waterproofing holds.
