One Design and Construct is a multi-award winning extension and addition builder in Western Australia.
If you could visualise your dream kitchen John and his team at One Design and Construct can build it for you.
With an extension and re-modelling of your home, why not include new bathrooms and ensuite to your master bedroom.
We are specialists in converting simple 3 X 1 houses into intelligently designed 4 bedroom, 2 bathroom homes, complete with master ensuite and garage all wrapped up with exceptional quality craftsmanship and finishes.
Invest in your outdoor living space that’s both functional and beautiful. Imagine relaxing on your spacious deck, or entertaining guests on your stunning, fully equipped patio.
We provide professional upgrade and renovation services for commercial and community facilities. Building needing some face lift? Talk to us.
Your character home lacking space to accomodate growing family? Why not extend at the back of the existing residence. Or it is possible to convert carport into an additional room and also have a lock up garage. Your 3×1 can be transformed to 4×2 home.
