Renovations and Extensions Framing Sydney
Structural framing for renovations and extensions across Sydney and Western Sydney — new framing tied cleanly into existing structures, to the engineer's drawings.
About this service
Renovation and extension framing is the structural carpentry that turns a design on paper into a usable extension or reworked space — new walls, new floors, new roofs, tied into a house that's already standing.
This service suits homeowners extending their home, builders running renovation projects, and project managers handling structural work on existing properties.
It's a different job to framing a new build. The starting point isn't a flat slab — it's a house someone has been living in, and the new work has to meet the old work cleanly.
What's included
We frame new walls tying into the existing structure, frame floors and ceilings for extensions, and carry out structural alterations called for in the engineer's drawings. Where structural elements need to be removed and replaced as part of the scope, we handle that to the documentation provided.
Everything is framed to the engineer's drawings on the job — not to a generic detail from the last renovation. Each project gets set out and framed to its own documentation.
Why this matters
Existing structures aren't perfectly square or level. A house that's been standing for decades has moved, settled and been worked on. New framing has to land cleanly against what's actually there, not what the original drawings said was there.
Tying new framing into older construction takes care. The interface between new and old is where renovations either look right or look like an add-on. We measure the existing structure, work to it, and frame the new sections so the join is clean.
On occupied homes, disruption matters. We plan the work to keep the site safe and the household functional through the build wherever the program allows.
Common problems we help our clients avoid
New framing that doesn't meet the existing structure cleanly
If the new work is set out off the plans without checking what's actually on site, the join shows. We measure the existing structure first.
Ignoring that the old house isn't square
Older homes move. We frame to suit what's actually there so the finished result lines up, instead of fighting the existing structure all the way through.
Framing without the engineer's drawings
Structural alterations on existing homes need engineering. We frame to the engineer's documentation, not assumptions.
Treating an extension like a brand-new build
An extension isn't a new house. We frame it as work that has to integrate with what's already there — not just sit next to it.
A simple, four-step process
Send through your plans
Email the architectural plans and engineer's drawings for the renovation or extension. We'll review them in context of what's already on site.
Walk the site and quote
Where it makes sense we'll look at the existing structure before quoting — the plans don't always show what's actually there. Then we send back a clear quote.
Schedule around the household and program
We lock in a start date that suits the wider build program and, where the home is occupied, plan the work to minimise disruption.
Frame on site
We frame the new sections to the engineer's drawings, tie them into the existing structure cleanly, and hand back work the next trades can move forward from.

Frequently asked questions
Do you frame both single and two-storey extensions?+
Yes. We frame single-storey additions and two-storey extensions, including the structural work to support the upper level.
Can you tie new framing into an existing older structure?+
Yes. That's most of what renovation and extension work is. We measure the existing structure on site and frame the new work to suit what's actually there.
Do I need an architect or building designer before you can quote?+
We need plans and engineer's drawings to give you a real quote. Whether they come from an architect, a building designer or a draftsperson is up to you.
Do you work in older homes across Sydney?+
Yes. Older Sydney homes are a regular part of the renovation work we do.
Can I send plans before booking?+
Yes — send the plans through first. We quote off plans, then book in.
Can you work around homeowners still living in the house?+
Where the program allows it, yes. We plan the work to keep the site safe and the household as functional as possible through the build.
