An extension is the most transformative thing you can do to a home — adding the light, space and connection to the garden that older floor plans so often lack. Done well, it doesn't just add square metres; it changes how the whole house feels to live in.

Haven Solutions designs and builds extensions across Melbourne as a single, accountable team. From a considered rear addition to a sweeping open-plan living zone, we resolve the design, engineering, approvals and build under one roof — so the new space feels like it was always meant to be there.

We think hard about orientation, ceiling heights, sightlines and the transition between old and new, so the join is seamless and the light is right all year round.

And because the same team designs and builds, the idea you fall in love with is the one we deliver — on a fixed price, with no value-engineering surprises.

FAQs

Home Extensions — common questions

Do you handle council approvals?

Yes. We manage the design, documentation, engineering and the planning/building approvals as part of the service, so you have one team accountable for the whole journey.

Can we stay living at home during the build?

Often, yes — especially for rear extensions where we can seal off the work zone. We'll talk you through what to expect before we start.
