How we build
Location
Margaret River WA

How a house goes up, lift by lift.

From the first walk on the block to the day we hand over the keys, the same builder runs the job. This is the order of things, and what we build with.

Set-out · Before the first lift

A bush block set out with timber profiles and string lines on pale sand, among eucalypts in morning mist

01Process

Five lifts, one builder.

Every house is different, but the order of things is not. Each stage is finished and checked before the next goes on, the way a rammed earth wall is built.

  1. Lift 01

    The block

    We start on site, with you. Where the sun comes from, where the wind and the views are, how the land falls and what already grows there. Bring your architect's plans, or bring nothing but the address.

  2. Lift 02

    The design

    If you have an architect, we build from their drawings and talk through how to build them well. If you don't, we design the house with you, shaped around the block and the light.

  3. Lift 03

    The price

    We price the house properly, go through it with you and only then agree to build it.

  4. Lift 04

    The build

    Slab, walls, roof, fit-out. Tom is on site through every stage, with the same small crew from the first peg to the last coat of oil.

  5. Lift 05

    The handover

    We walk the finished house with you, explain how it works through the seasons and hand over the keys.

02Passive solar

Season
Section drawing of a north-facing house showing the noon sun at midwinter, about 33 degrees, and at midsummer, about 79 degrees.33°MIDWINTER NOON79°MIDSUMMER NOONEAVEEARTH WALLTHERMAL MASS SLABNORTH

Midwinter noon, about 33°. The low sun slides under the eave and reaches deep across the slab.Midsummer noon, about 79°. The high sun is held off the glass by the eave, and the rooms stay in shade.

Set the eave to the latitude.

At Margaret River the noon sun stands about 33 degrees above the horizon in midwinter and about 79 degrees in midsummer. A well-set eave knows the difference.

Face the living spaces north, size the eave to the latitude and put heavy material where the winter sun lands. The slab and the earth walls take in warmth by day and give it back at night.

03Materials

Local, honest, heavy.

Four materials do most of the work on our houses. We choose them for how they handle this climate, and for how they will look long after we have packed up.

  1. S.01
    Close view of a rammed earth wall showing its compacted layers in ochre, clay and rust tones

    Rammed earth

    Damp earth compacted in layers, one lift at a time. Thick, cool in summer and slow to give up its warmth in winter.

    Goes into Feature walls, load-bearing walls, hearths

  2. S.02
    Close view of oiled jarrah with deep red interlocking grain

    Jarrah

    The South West's own hardwood. Deep red, dense and hard wearing, and better for every coat of oil.

    Goes into Decks, benchtops, joinery, stairs

  3. S.03
    Close view of sawn limestone blocks with fossil shell and a mortar joint

    Limestone

    Sawn local stone, pale and porous and full of old shell. It takes the coastal weather in its stride.

    Goes into External walls, chimneys, garden walls

  4. S.04
    Close view of recycled hardwood boards with old nail holes and flecks of paint

    Recycled timber

    Hardwood boards from old buildings, nail holes and paint and all, given a second working life.

    Goes into Floors, ceilings, cladding

New-home consultation

Start with the block.

Bring an architect's plans, a survey or just an address. We will talk about the site, the sun and what you want to build.
