New Homes

Extension-by-Design deliver stunning and practical residential design solutions. Our strength is our ability to achieve outcomes that others find challenging.

Our experience is wide and broad,

  • Single Storey Additions
  • Double Storey Additions
  • Single Storey New Homes
  • Double Storey New Homes
  • Designer Homes for Narrow Lots
  • Split level homes for sloping blocks
  • Homes with under-crofts
  • Courtyard Homes

We have over twenty (20) years of professional architectural design and building experience in Perth, working in Extensions and Additions as well as new homes.

Our strength is the in-depth building knowledge that we have to compliment our extensive design expertise. We understand the difficulties and cost implications that impractical design poses the process.

An impressive design on paper does not always translate into workable solution. We always maintain a realistic perspective that delivers an workable outcome. Our designs are elegant, functional, and very importantly, are easy to build and cost effective.
