Extensions and second storey additions

More room, more light, and a house that finally works, without leaving the suburb you chose.

Adding to a house you already love

Most Perth homes have more potential than their owners realise. A rear addition or a second storey can transform how a house works without the cost and upheaval of moving. We design additions that read as part of the original house rather than something bolted on, and document them so your builder can price the job with confidence.

Old and new, resolved

The hardest part of an addition is the join. We design the transition between existing and new so the finished house looks intentional, not patched.

Structural reality early

Second storeys depend on what is underneath. We identify structural and footing implications during design, not after you have committed.

Approvals handled

Setbacks, overshadowing, privacy to neighbours and open space. The issues that stop additions at council are the ones we design around from the start.

Live-in staging

Where possible we plan the works so you can stay in the house during construction, or at least shorten the time you cannot.

Questions

Common questions

Is it cheaper to extend or to move?

It depends on the scope, but stamp duty, agent fees and moving costs on a Perth property are substantial before you have gained a single square metre. An extension keeps you in the suburb and the school catchment you chose. We can give you an indicative build cost range during concept design.

Can every house take a second storey?

No. It depends on the existing footings, wall construction and the roof structure, as well as the planning controls on your lot. We assess feasibility before you spend on full documentation.

Will an addition match the existing house?

That is a design decision, not a default. Some additions are best matched to the original; others work better as a clearly contemporary element. We show you both approaches before committing.

What approvals do I need?

Generally a Development Application to your local council and then a Building Permit. Heritage listings, special control areas or non-complying setbacks add requirements, which we identify at the start.
