Extensions That Match the Existing Home

Home extensions are where most builds go wrong — roof lines that don’t match, doors that don’t line up, new work that looks obviously bolted on. We don’t do that. Every TreadstoneCPM extension starts with a proper assessment of the existing structure, the roof line, and the finishes, so the new work is structurally sound AND looks like it belongs.

We handle the full extension process: architectural plans, structural engineer, council submission to George Municipality (or your local authority), NHBRC enrolment where required, build, snag, and clean handover. One contract, one contact, one accountable team.

What a Home Extension Includes

Structural assessment — We check the existing foundations, walls and roof can take the new work. Structural engineer sign-off before any concrete is poured.
Plans & council submission — Architectural plans, engineer’s drawings, SANS 10400 compliance, and building plan approval through George Municipality or your local authority.
Matching finishes — We match existing face brick, plaster, paint, roof sheeting or tile, and window frames so the extension looks original, not bolted on.
Roof tie-ins — Proper flashing, valley and gutter detailing where the new roof meets the old. Waterproofed before the first rain.
Electrical & plumbing extensions — COC-compliant extensions of the existing electrical and plumbing reticulation, inspected and certified.
Fixed price, fixed programme — Line-item quote, written programme, payment schedule and workmanship guarantee agreed before signing.

How a Home Extension Runs

1. Site visit & concept

We walk the existing home with you, talk through what you want to add, and give you an honest view on what’s feasible, what’s council-approvable, and roughly what it costs.

2. Plans & quote

Architectural plans drawn, engineer involved, council submission prepared, and a full line-item quote for the build. Nothing starts until the plans are approved and the quote is signed.

3. Build, snag, handover

Tidy site management, weekly progress, formal variation orders on anything that changes, snag walk, and handover with written workmanship guarantees.

Common Questions

Do I need council approval for a home extension?

Yes — almost always. Any addition that changes the footprint, adds a storey, or alters a structural element needs council-approved plans under the National Building Regulations. We handle the submission for you through George Municipality or your local Garden Route council.

Can you build a second storey on an existing home?

Yes, provided the existing foundations and walls can carry the load. We do a structural assessment with an engineer before quoting. If the existing structure can’t take it, we’ll tell you upfront and discuss alternatives like a ground-floor extension or a separate granny flat.

Do you do granny flats and separate outbuildings?

Yes. Granny flats, second dwellings, pool houses, studios and garages — all delivered under the same contract format as a main build, with council approval and NHBRC enrolment where applicable.

How long does a typical home extension take?

Small extensions (single room, no roof tie-in) run 6–10 weeks on site. Larger extensions with roof work and full finishes run 3–5 months. The exact programme goes into your written quote before you sign.

Will the extension match the existing home?

Yes — that’s the point. We match face brick, plaster texture, paint colour, roof sheeting and tile profile, and window and door frames so the extension reads as part of the original home, not a bolt-on.
