About Us

As certified passive house builders, we only work with passive house building projects and high performance renovations and extensions. We have an extensive understanding of the technical building methods and different cosmetic finishes required to build passive house homes.

Some of the renovation-specific skills we employ when working with older homes are:

Technical skills

  • Knowing how to remediate, strengthen, and bond old brittle house structures to new concrete slabs
  • Correctly connecting new walls to existing walls to avoid differential movement and cracking
  • Levelling and straightening old floors to blend neatly with new floors
  • Identifying the structural repairs required to improve the liveability of existing buildings and prolong their lives

Cosmetic skills

  • Being able to recreate period features, such as verandah fretwork, tessellated tiles, corbels, and cornices from old photographs and historical drawings
  • Creating harmonious junctions between old and new, and blending modern architectural extensions seamlessly with the period features of the original home
  • Selecting energy-efficient products and materials that suit the character of the original building while enhancing its thermal performance and energy efficiency
  • Providing sensible, balanced advice on which parts of a home are fixable, and which parts warrant demolition

We love building passive homes that are efficient and sustainable.

We‘re a small domestic building business with more than ten years’ experience in residential construction. What sets our company apart, and the reason our clients choose us to renovate or extend their home, is that we do one house at a time, from start to completion.

Our difference is our carpentry-based focus, small company structure and hands-on approach.

We love our hands-on work and choose to keep our building and carpentry work in-house and minimise the use of external contractor crews. To some builders this is an old-fashioned approach, but our clients will attest to the quality and efficiency of work it produces.

Our daily on-site management means we:

Execute first-class workmanship

To give you a better result

Keep sites clean and well organised

Allowing you to live onsite when safe

Run projects efficiently and on schedule

Saving you time and hassles

Be realistic and competitive in our pricing

Helping you get the most from your budget

This means that we are selective in the amount of work we take on at any one time and it ensures that we can give our full attention to every project from start to finish. This also means we complete projects with the utmost efficiency. Because we are on site every day, things move very quickly. A large, 60mweatherboard home extension typically takes us around 10-13 weeks from start to final handover. This means you are back in your home much sooner than if you were to use a builder who manages the work off-site with contract labour.
