Build a better everyday.
Thoughtful renovations, extensions, second dwellings, wet-area renovations, new builds, and occasional commercial fit-outs made for the way life actually unfolds.
The BOS approach
Good building is good listening.
01
Start with how you live
We make the brief practical first: the light, the flow, the things that need to work on an ordinary Tuesday.
02
Make every decision clear
From early estimates to final finishes, we keep the process open, collaborative, and grounded in what matters to you.
03
Build for the long view
Refined materials and proven construction keep the result beautiful, durable, and ready for the years ahead.

The process
How BOS works
Initial enquiry
Brad answers directly, asks what you are planning and where, with no call centre and no handballing between staff.
Site visit
Brad comes out himself and looks at existing conditions, levels across the site, access for construction, what may be behind existing walls, and how the block limits or supports the work.
Planning
Before anyone prices the construction, the project gets properly defined — engineering, soil tests and working drawings as the job needs them — so you know what you are actually building.
Proposal
A real scope and price, with provisional sums identified openly as flexible allowances rather than hidden extras.
Construction
Brad is on site and on the tools, with one point of contact the whole way. A typical project runs around 7.5 weeks depending on scope.
Handover
Brad walks through the finished work with you and sorts any outstanding items.

Proof of practice
Credentials
20 years of experience, Master Builders Victoria member, registration BPC DB-U 38574.
Custom homes
BOS builds custom homes: one-off houses for the people who will live in them, rather than volume or spec building. The same people who answer the phone and run the site stay with the job from start to finish, using the same six-step process as a renovation from the first conversation through handover. This work is carried out across the Calder corridor and inner-south Melbourne. For South Melbourne projects, see our master builder services in South Melbourne.
