2ndDawn SUSTAINABLE HOMES
Free 12-page owner's guide

Built for Perth.Built for life.

The eight decisions that determine whether the home you build is comfortable, healthy and cheap to run — for the next fifty years. Most of them are settled before anyone digs.

  • Why 7 stars is the floor, not the goal — and what WA left out of the 2025 code changes.
  • The sun angles that decide your eaves — 81° in midsummer, 35° in midwinter, at our latitude.
  • Where the money actually goes — provisional sums, variations, and why a free quote costs you more.
  • Twelve questions to ask any builder — including us.

By the time you're choosing tapware, the important decisions are behind you.

Orientation, form, envelope and glazing are locked in at design — and they set how the home will feel and what it costs to run for the rest of its life. Here's what's inside, in the order the decisions actually get made.

01

Start with the block

Orientation is free. Nothing else buys as much comfort.

02

Let the block shape the plan

Zoning, room placement, and why two storeys suits infill.

03

The envelope

Insulation, thermal bridges and the gaps nobody sees.

04

Glass and shade

Your windows are the weakest part of the wall.

05

Air you can't see

Ventilation, moisture and indoor air quality.

06

What it costs to run

Whole-of-home: the bill that arrives after the build.

07

Where the money goes

Honest pricing, and why free quotes cost you more.

08

Choosing who builds it

Twelve questions worth asking any builder.

“We chose 2ndDawn after talking to a number of builders. Their quality, their devotion to the build, their construction process, and their passion for sustainable homes set them apart.”
