Bungalow construction, extensions and renovation

Overview

Right now we are building a two-storey bungalow in Kajang

Pretech is the main contractor for a private bungalow on Lot 34746 at Impian Golf & Country Resort, Kajang — pad foundations and stumps, reinforced concrete frame, suspended slabs, brickwork, roof, M&E first fix and internal finishes, built to the architect's and structural engineer's drawings and certified progressively by the consultant.

Before that we completed 49 single-storey terrace houses at Mukim Linggi for SV Construction, staff quarters for Felda Sungai Lui, a Tamil school building at Sungai Pelek for Malliga Krishnan Sdn Bhd, and a school canteen extension at Sungai Gadut.

Building work sits naturally on top of what we already do. The earthworks, the piling platform, the drainage, the sewer connection, the apron and the driveway are all our own trades — so there is one contractor answerable for the whole plot, not five.

How we work

How a job runs

Talk it through

Send us the location of your land and any drawings you have. If you have none yet, we will tell you what you need and roughly what it costs.

Site visit and buildability check

Access, levels, soil, drainage, setback and the neighbouring boundary — the things that quietly add cost if nobody looks at them early.

Bill of quantities and quotation

Priced against measured quantities and your drawings, stage by stage, with exclusions written down instead of discovered later.

Stage-by-stage construction

Payments follow completed and inspected stages, with progress photographs sent by WhatsApp as the work goes up.

Snagging and handover

A walk-through, a written defects list, and the list closed out before final payment.

Who we work for

Owners building on their own land

Most people who build a bungalow do it once. That means the contractor has to explain as well as build — what a stage payment covers, why the frame costs what it does, what happens if the specification changes halfway.

We are comfortable working under an architect and a structural engineer and being certified by a consultant, which is how the Kajang bungalow is run. If you would rather we help you assemble that team, we can point you to people we have worked with.

  • Owners with land and drawings ready to build
  • Owners with land but no drawings yet
  • Families extending or renovating an existing house
  • Owners whose previous contractor abandoned the job
  • Developers building small numbers of units
  • Temples, schools and community buildings
FAQ

Bungalow Construction — questions we get asked

What does a bungalow cost per square foot?
Anyone who answers that without seeing your drawings is guessing. The frame, the roof type, the soil, the finishes and the site access all move the number substantially. Send us your drawings or your rough size and we will give you a range, then a measured quotation.
Do I need an architect and an engineer?
For a new bungalow, yes — submission and structural design must be by qualified consultants. We build to their drawings. For an extension or a renovation, the requirement is smaller but usually still there, and we will tell you what applies.
How are payments structured?
By completed stage — foundation, frame, roof, brickwork, finishes — against work you can see and, where there is a consultant, against their certificate. We do not ask for large sums in advance of work done.
My contractor abandoned the job. Can you take over?
Often yes, and we have done it. We would first inspect what has been built and be honest about what has to be redone — taking over a bad frame and pretending otherwise helps nobody.
How long does a bungalow take?
A straightforward two-storey bungalow is typically 12–18 months from site possession to handover, depending on size, the finishes and how quickly decisions get made. Weather and variation orders are the usual causes of delay.
Can you do the driveway, drains and boundary wall too?
Yes — those are our core trades. Having one contractor for the house and the external works is usually cheaper and always simpler.
