Architecture for every chapter of life — from first homes to care-ready spaces. de.arch is a boutique architectural practice based in Melbourne.

We specialise in Residential, SDA, and Allied Health design that’s thoughtful, practical, and personal. Our passion is designing spaces that are individual, enriching and timeless. Whether it be a new house or development, renovation, extension or internal refurbishment, our belief is that every project offers the opportunity to inspire and excite our clients, customising projects to reflect their aspirations and budget. This requires our highest attention at every stage but most importantly listening to and understanding the nuances of how our clients live and work.

Did you know that today is so we thought we’d say hello and introduce ourselves to those who have recently found us. Hello! We are de.arch. Pronounced de-arc. We are a female founded and led architectural practice in Melbourne. We’re a tight knit team that focuses mainly on residential work. So if you’ve reached out to us or work with us already, chances are, who you see here is who you work with. Kinda nice huh! Putting a face to the name. If you ever see us around, please say hi!

It’s hard to believe this is the same home.

Once a dilapidated heritage home in need of some serious care, it’s now been given a new lease on life - with its original heritage features carefully restored and the rest of the home modernised and upgraded to achieve a 7-star energy rating.

A thoughtful collaboration between developer, builder, architect and interior designer has brought together the best of old and new.

Now, this Thornbury home is ready to be enjoyed by its new owner for its next chapter!

8 months has flown by and today our St. Kilda East project reached 2 huge milestones - practical completion and its certificate of occupancy. It’s lucky family soon to have the space all to themselves once again and ahead of schedule! Vision superbly executed by Peter Brown - as always.

Not yet a before and after… but an existing and proposed!

This three-level riverside home in Hawthorn is proposed to be modestly extended, while its existing layout is extensively reworked and renovated to make the most of its incredible setting.

The result is a home carefully reoriented around the views - including that epic golden hour aspect. ☀️

What a week and happy Friday! We thought it was time to relax into the weekend and who doesn’t love some dog pics and architecture combined. Here are a couple of our favourite clients

Can we just take a moment and appreciate the natural beauty of this Blue Patagonia Quartzite? Literally took my breath away. This heritage home in St. Kilda is so very close to the finish line - all the beautiful materials, finishes and details finally coming together. Peter Brown Surface Spectrum

Brunswick House renovation and extension carefully restored the home’s heritage charm (that is…what was left of it) while replacing years of DIY alterations with a thoughtful family focused design. A light filled extension, flexible spaces for three generations and a new seamless connection to the outdoors have completely transformed this home.

Blower Door Test Day!

A great milestone for our Passive House project in Box Hill yesterday, with the blower door test completed before plastering.

This test measures the airtightness of the home and helps identify any air leaks while they’re still easy to address. We’re pleased to report a result of 0.58 ACH (air changes per hour), exceeding the Passive House certification Standard of 0.6 ACH!

What does that mean in practice? A more airtight home is more energy efficient, reducing the need for heating and cooling. Combined with a Heat Recovery Ventilation (HRV) system, it also provides a continuous supply of fresh, filtered air, helping to reduce dust, pollen and other allergens while maintaining a comfortable indoor environment.

A fantastic result and a credit to the attention to detail from the team at Coy’s Constructions

We had the privilege of attending the official opening of two brand new Specialist Disability Accommodation (SDA) homes this morning.

We’re incredibly proud to have been part of the team that brought these homes to life alongside Harnest, BlueCHP and Bayley House.

Located in Mentone, these homes have been thoughtfully designed and tailored to meet the unique needs of five individuals, creating forever homes that will support them for years to come.

Seeing the smiles on the faces of the new residents and their families made every challenge along the way worthwhile.

A heartfelt congratulations to everyone involved in making this project a reality.
