Houses shaped by their site.

We design new coastal houses and careful additions to old ones. Eight to ten projects a year, and a director leads every one of them, from the first site visit to the day you get the keys.

  • 112 houses completed

  • First meeting free, on your site

01 Practice

Small on purpose. Every house is led by a director.

Most practices grow by taking on more projects and handing them down the line. We've stayed at six people in a studio in Cooks Hill, because the alternative is a house designed by someone you met once. Merrin or Lachlan leads your project at every meeting, on every drawing set and at every site inspection.

We only work across Newcastle, Lake Macquarie and the Central Coast. We know the councils, the coastal hazard maps and the builders who can pour a good off-form wall, and we can be on your site within the hour.

02 What we design

Three kinds of work, done properly.

  • 01

    New coastal houses

    Steep blocks, exposed headlands and lake edges, where wind, salt, bushfire ratings and the view all pull in different directions. We spend a day on the block before we draw anything, then design around sun, breeze and how you'll actually live in the rooms.

    • Construction budgets of $1.4m to $3.5m
    • Bushfire and coastal hazard reports coordinated
    • Passive solar design, modelled, not guessed
  • 02

    Heritage alterations and additions

    Terraces on The Hill, Federation cottages in Hamilton, interwar bungalows in Merewether. We keep what's good, take out what isn't and add rooms that are clearly new without shouting about it.

    • Heritage impact statements written in-house
    • Measured drawings of the existing house
    • Staged builds so you can often stay living there
  • 03

    Small hospitality

    One or two a year: a beach kiosk, a cellar bar, a twelve-seat wine room. They're small, hard on budgets and a lot of fun, and they keep our residential detailing honest.

    • Pavilions and fit-outs
    • Accessibility and food premises codes coordinated
    • Fit-out budgets from $350,000

03 Selected work

Four recent projects, with the numbers that shaped them.

Site, sun, area and budget come first in every project we take on, so that's how we show them. Photographs and drawings, no renderings.

05 Process

How a house gets drawn.

Five stages. Usually 12 to 18 months from the first visit to a building approval, then construction. You'll always know which stage you're in and what it costs.

  1. 012 to 4 weeks

    Site and brief

    We walk the block with you at different times of day, order the survey and geotechnical report, and write the brief in plain English. Sun angles and breezes go on the drawing before any walls do.

  2. 026 to 8 weeks

    Concept design

    Two or three distinct options in sketches and card models, each priced by a quantity surveyor. You choose one, or we combine the best of them.

  3. 038 to 10 weeks

    Design development

    Rooms, windows, eaves and materials get resolved. We work out exactly where the winter sun lands and how the summer sun is kept off the glass.

  4. 044 to 6 months

    Approvals and documentation

    Development application or complying development, then a full construction set: drawings, specification and schedules, detailed enough that every builder prices the same house.

  5. 0510 to 16 months

    Tender and construction

    We tender to three or four builders we trust, inspect the site every fortnight, check every progress claim and walk the defects list with you.

06 Fees

How we charge.

Most clients take our full service, charged as a percentage of the construction cost and agreed in writing before we start. If you only need a feasibility study or a concept, we'll quote a fixed fee.

  • Feasibility study

    $4,800

    fixed fee, plus GST

    A site visit, the planning controls, a one-page brief and a realistic construction budget. Worth doing before you buy a block or commit to renovating.

  • Concept design

    from $18,500

    fixed fee, plus GST

    Stages one and two: site analysis, two or three priced options and a card model. The drawings are yours to take to any builder.

How the full-service fee is spread

  1. 15% Site and concept
  2. 15% Design development
  3. 40% Approvals and documentation
  4. 30% Tender and construction

On a $2m house, a 12 per cent fee is $240,000 plus GST, paid monthly over about two and a half years. Consultants such as the surveyor, engineer and bushfire consultant are billed at cost, and we'll estimate them in your fee proposal.

07 Studio

Six people, one room in Cooks Hill.

You'll meet both directors before you sign anything, and you'll have their mobile numbers once you do.

  • Merrin Hale

    Founding director / Registered Architect, NSW

    Started the practice in 2011 after eight years designing coastal houses in Sydney. Leads most new houses and still does the first sketch for every project.

  • Lachlan Dorey

    Director / Registered Architect, NSW

    Joined in 2014 and became a director in 2019. Runs our heritage work and the construction phase, so he's the one on site every second Tuesday.

  • Anouk Teale

    Associate / Registered Architect, NSW

    Leads documentation. When a builder rings with a question about a junction, Anouk has usually drawn it already.

  • They spent a whole Saturday on our block before they drew a line. You can feel it in the house.

    Fiona, Caves Beach

  • Lachlan was on site every fortnight for eleven months. Our builder said it was the clearest set of drawings he'd priced all year.

    Tom, Merewether

  • We expected the heritage process to be a fight. It took one meeting with council.

    Jo, The Hill

08 FAQs

Questions we hear at the first meeting.

Something else on your mind? Call 0491 570 159 and you'll get Merrin or Lachlan, not a receptionist.

What does a house like this cost to build?

Most of our new houses come in between $1.4m and $3.5m in construction cost, roughly $5,500 to $9,000 a square metre on coastal sites. Additions vary more. We'll give you an honest range at the first meeting and test it with a quantity surveyor at concept stage.

How long does the whole thing take?

Allow 12 to 18 months for design and approvals, then 10 to 16 months to build. Heritage conservation areas and bushfire-prone blocks sit at the longer end.

Do we have to use a builder you choose?

No. We usually tender to three or four builders we know well, and you're welcome to add your own. If you already have a builder in mind, we'll work with them on a negotiated contract.

Will you do drawings just for council?

No. Drawings done only to get an approval leave the hard decisions to the builder, and that's where budgets go wrong. If you'd like a lighter start, our concept design fee is the closest option.

Do you work outside the region?

Occasionally, if the site is within about three hours of Newcastle. We won't take on a project we can't inspect in person every fortnight.

What should we bring to the first meeting?

A rough budget, a survey if you have one and a list of what isn't working in your current home. Pictures you like help, but they're not essential. The meeting is an hour, and there's no charge.
