Home Extension Builders in South West Sydney

An extension adds space to the home you already have. The aim is new rooms that join the existing house naturally and suit the way your household lives now.

Adding space

What to think about with an extension

  1. What the extra space is for

    A bigger family room, another bedroom, a second bathroom or a home office. Knowing the purpose shapes everything else.

  2. Joining old and new

    How the new rooms connect to the existing house, so it feels like one home rather than an add-on at the back.

  3. Layout and flow

    Where you walk through, where light comes in, and whether any existing rooms change to make the new space work.

  4. Access to the yard

    Many extensions open onto the backyard. Think about doors, step-downs and what happens to the outdoor area you have now.

  5. Your household day to day

    Building work changes how a home runs for a while. Think early about how your household will manage during the build.

Out, up or update?

Extending out

Adds rooms at ground level, usually at the back or side. Uses some of the yard.

Building up

Adds an upper level and keeps the yard. See second-storey additions.

Reworking what is there

Sometimes the space exists but the layout does not work. See renovations.

Before you get in touch

  1. Your address

    The street and suburb, and whether the house is brick, weatherboard or something else.

  2. Existing plans

    Any floor plans of the current house, even old ones, plus photos of the area you want to extend.

  3. What you need

    The rooms you want to add and what is not working in the home now.

  4. Your yard

    How much backyard you have and how much you would be happy to give up.

Common questions

Can we stay in the house during the build?

That depends on the work and your household. It is worth talking through early, and some families plan to stay elsewhere for parts of the build.

Is an extension better than moving?

It depends on your block, your budget and what you need. An extension makes most sense when you like where you live but need more space.

Can an extension include a new kitchen or bathroom?

It can. Tell us what you have in mind and we can talk through the scope.
