MDC Architects is eagerly awaiting the introduction of Western Australia’s new Medium Density Codes –in April 2024 – which will pave the way for more diverse housing and vibrant communities across Perth.

MDC Architects is enthusiastic about the introduction of the state’s new Medium Density Codes – part of the amended State Planning Policy 7.3 – which will become operational following gazettal on 10 April 2024.

The Codes were originally due to come into effect in September 2023, but their introduction was deferred by the Housing Minister John Carey, and Matt Delroy Carr joined other architects to lobby for their reinstatement.

The new codes will make it easier for our clients to provide different types of housing – such as grouped dwellings and multiple dwellings – on various lot sizes, as defined by the R-Codes.

Details of the changes can be found on the government’s website here.

MDC Architects founder and principal architect Matt Delroy-Carr is looking forward to designing new homes that meet the provisions of the new Codes, because they make it easier to deliver well-designed and affordable housing for people at all ages and stages of life.

“The new Medium Density Codes provide significant opportunity for our clients to design and deliver innovative housing into a market that has traditionally been dominated by four-bedroom, two-bathroom homes,” he explains.

“Now we can innovate and provide smaller, more sustainable homes for people in established neighbourhoods, so that younger home buyers can afford to stay in the suburbs where they grew up, and older people thinking about downsizing or right-sizing can stay in their local communities, close to friends, family, healthcare, and all the other services they’ve grown to enjoy over many years or decades.

“These new codes will streamline the way that we as architects help our clients to navigate the planning system, so that together we can deliver more diverse and appealing housing for Perth residents. They provide new options and better liveability in comparison with a lot of the current housing product in the market currently.”

MDC Architects has established its leadership credentials in this new type of development in Perth, having already completed multiple projects that will become much more feasible and easy to replicate now, under the new codes. Our past projects include:

In addition, our New House Plans bring good design into the hands of more people, because they are an affordable way to build an architect-designed house in an established suburb – within 20km of the CBD – without the usual architects’ fees.

So if you’re looking to develop a new multi-residential project to meet the needs of Perth residents who value affordable good design, or you’ve got a site that’s ripe for a smarter, smaller, more home, we invite you to get in touch. You can email Matt at or call him on 0405 003 035.
