Home Extensions in Perth.

Sometimes the right move is not to move, but to build.

Ground-floor extensions, second-storey additions and alfresco areas on Perth's coast, from Fremantle to Mullaloo.

What We Build

Extensions We Build.

Sometimes the right move is not to move, but to build. A well-planned extension gives you the space you need and keeps you in the home and suburb you already like. We build extensions that feel like part of the original house, not an add-on.

01.

Ground-Floor Extensions.

The most common type: extra living space, a kitchen and dining area, or more bedrooms at ground level. We take care over the join between old and new so it feels seamless.

02.

Second-Storey Additions.

A full or partial upper floor on an existing single-storey home. It needs a careful structural assessment, but on smaller coastal blocks it's often the most practical way to add a lot of space, and sometimes a view.

03.

Alfresco and Outdoor Living.

Covered alfresco areas, outdoor kitchens and entertaining spaces that connect to the house, with shelter from the afternoon sea breeze and western sun.

04.

Garage Conversions and Studios.

Converting a garage into a habitable room, or adding a studio, home office or granny flat. Each needs approvals and careful detailing.

Good Design

What Makes a Good Extension?

An extension adds square metres. A good extension adds the right square metres, in the right place, connected to the house so the whole home works better.

​

The decisions that matter:

Orientation

Where the light comes from and how it changes through the day and the year.

Connection

How the new space flows from the existing living areas.

Services

Extending plumbing, electrical and mechanical systems without creating problems in the existing house.

Materials

Matching, or deliberately contrasting, the existing home's palette and textures.

Step by Step

Our Extension Process.

Stage 1

Initial Consultation

We meet on site to understand what you want, look at the existing structure, and talk through what's achievable within your budget.

Stage 2

Design and Approvals

We work with your architect or designer, or can recommend one, to develop the design and work through the approvals. Most extensions in Perth need a building permit from your local council, and some also need development approval. See our FAQs for how approvals work in WA.

Stage 3

Construction

We coordinate the trades and materials, keep you informed as work progresses, and keep disruption to your household as low as we can.

Stage 4

Completion

Before handover we walk through the extension with you and fix any defects before we hand over the keys.

Priced for Your Project

What Will My Extension Cost?

Cost depends on the design, size, site and finishes, as well as how much structural work the existing house needs. After an initial consultation, we provide a detailed, itemised quote for your project, not a generic square-metre rate.
