Floorplan for knockdown rebuild project

Knockdown rebuild design. Reimagine your home on land you already own

Building designer for knockdown rebuild projects across Melbourne's western suburbs

Your block is worth keeping. The house on it may be a different matter. If you have outgrown your home, or bought knowing the house would eventually need to go, a knockdown rebuild gets you the home you want. We take projects from the first design conversation through to approved plans, finishing at precisely the point a builder can start.

Rebuild or renovate?

Not every property is suitable for renovation. A house with structural issues, or a layout that bears no relation to how your family lives is often better replaced than preserved.

A renovation that addresses structural problems, reworks the floor plan, and brings a home to current standards can cost as much as a tear down and rebuild, sometimes more.

What a building designer does on a knockdown rebuild

Builders offering knockdown rebuild packages work backward from a product they have built many times. Your new home is a selection exercise from a fixed catalogue.

Our process works the other way. Your land and your brief are the starting point, and the design develops from there. We work with you through layout options until the floor plan feels right and functions perfectly for you.

How the knockdown rebuild process works

It begins with a site assessment reviewing your block, checking planning overlays, and building a clear picture of what rules apply before any design work begins. Concept design follows, developing a response to your brief and your block until the floor plan takes real shape. Design development brings those drawings to the level of detail needed for permit applications and accurate builder pricing.

Where a planning permit is required, we prepare the documentation for your council. Demolition approval and demolition permit documentation is handled at this stage, not left to the builder to sort out separately. Building permit documentation completes the set, giving your chosen builder everything needed to begin work on site.

Knockdown rebuild cost in Melbourne

How much does a knockdown rebuild cost is the question that opens almost every first conversation, and the honest answer is that the total depends on what you are building, what your block requires, and the level of finish you are after.

House demolition cost in Melbourne typically runs between $15,000 and $30,000 for a standard suburban dwelling, varying with building size and site access. New home build costs in Melbourne's western suburbs currently sit in the range of $2,500 to $4,000 or more per square metre for a quality result, shifting with specification and current industry pricing.

Our design and documentation fees are fixed, transparent, and scoped in writing before you commit to anything.

Knockdown rebuild duplex and investment projects

A knockdown rebuild does not have to produce a single dwelling. For homeowners with a larger block or development potential, a knockdown rebuild duplex project follows the same design and permit pathway but produces two dwellings and a Torrens title subdivision opportunity at the end of it. For knockdown rebuild investment property projects where return on the land is the primary goal, the design brief shifts accordingly and we work through the development yield and planning pathway from the outset. Each project type carries its own approval process and we map that clearly before design begins.

Knockdown rebuild design specialists in Melbourne's western suburbs

Melbourne's western suburbs carry planning rules, council processes, and neighbourhood character considerations we know from working here consistently. The difference between a designer who understands the local planning picture and one learning it on your project shows up at permit stage, not at the concept sketch, and that is a costly point for surprises.
