building Design and Drafting

How can we help you?

Longhouse Design is a full service Building Design and drafting studio, here to help you create a beautiful, functional, and sustainable home.

We believe that the practice of architecture is something that should be a shared experience. Your situation, life, and land are all unique to you, and your contribution to the design of a new home or renovation is vital to achieving a great result.

Together we will create a bespoke building design that is crafted for you and the way you live. Your home will be something unique and special, just like you. It will support your lifestyle and protect you and your family.

The world is changing and the time of homes built just for nuclear families is coming to an end. You can create the life and community you choose, with a home for yourself, a couple, family, extended family, or even larger groups of friends or soon-to-be-friends.

Our goal as building designers is to create innovative and functional architecture guided by centuries of traditional building practice. Starting with the best principles of sustainability in design, community, and materials we strive for energy efficiency through passive design to craft truly sustainable and future-appropriate homes.

We can help you to create a custom home, or supply off the shelf plans for council approvals.

We service all regions in Sydney and the South of NSW:

– Sydney

– Shoalhaven

– South Coast

– Southern Tablelands
