Full design & build service
Maybe you’ve got a rear block, a battle-axe lot or an irregular site in an established Perth suburb. You love the location, but you’re not sure anyone can make it work.
Does this sound familiar?
101 Residential specialises in exactly these situations. We understand what makes infill sites different and we know how to unlock their potential.
From your first conversation through to handover, we guide you every step of the way, helping you navigate design, approvals and construction with confidence.
For more than 15 years, we’ve designed and built homes across Perth’s most complex infill sites.
We approach each block on its own terms, designing homes that work with site conditions, not against them.
The result is a home that feels considered, functional and naturally suited to its surroundings.
Let’s turn your block into something extraordinary.
Some blocks need more than a standard design, which is why many builders avoid them. Here’s where we specialise:
Maximising access, outlook and privacy on split lots behind existing homes.
Clever design solutions that make the most of driveway access and site orientation.
Smart floorplans that feel open and liveable regardless of the block’s width.
Custom design that responds to unusual shapes, slopes and angles.

Akshita and Arun chose to build a spacious single storey home designed to accommodate the needs of their growing family. They decided to build in an established suburb close to schools and everyday amenities.
" We wanted to know that there was stability behind the company, so I did a lot of research, and I felt very comfortable building with 101. "
