12 Eagle Bay Shack.
EAGLE BAY HOLIDAY HOME
12 Eagle Bay Shack is a completed, architect-designed Eagle Bay holiday home in Western Australia. Set high on the ridge above the bay, it has a strong connection to bushland, birds, ocean air and place.
It carries the relaxed mi shack® spirit, but this is no compact holiday shack — it’s a generous coastal home built for family time, fresh air, longer stays and future South West living.
High on the ridge. Calm above the bay.

Design idea: A generous coastal holiday home shaped around family, fresh air, outlook, relaxed living and a strong connection to place.
Why it matters: Proof that MIDS scales up into a generous Eagle Bay coastal home without becoming generic.
THE SITE.
Eagle Bay sits high on the ridge above the bay, and from that elevated position the home connects hard with the coastal landscape, the surrounding bushland and the changing South West weather. It’s a beautiful spot — but a beautiful site still needs a careful design response.
The home had to handle outlook, privacy, wind, natural light, summer use, longer stays and plain everyday comfort. So it’s shaped around coastal living and practical family use in equal measure. Rather than compete with the site, the house sits calmly within it.
THE BRIEF.
The brief was a relaxed Eagle Bay holiday home for a family with a global life and a strong pull back to Western Australia. From the start it needed to feel calm, useful and a little bit special — somewhere to host family stays, guests, fresh air, long lunches and quiet mornings, and eventually a base for more time in the South West.
That ruled out anything flashy or overworked. The house needed to be generous, clear and easy to live in — and, above all, a place people could return to over the years. Not just a holiday house. A South West base.
THE DESIGN RESPONSE.
The design response is calm, generous and coastal. Eagle Bay starts from the MIDS system, which organises the home into clear zones — living, sleeping, bathing, gathering, outdoor and the everyday coastal routines in between. (Modular here doesn’t mean prefab or factory-built; for mi shack®, modular means clear, predefined zones and elements that adapt to the site, the brief and the budget.)
On this project, the system was scaled up for a generous home. Large openings pull in natural light and tie the house to the landscape, while simple forms and a restrained material palette keep the whole thing calm. The result has real scale without losing its sense of place.
GENEROUS, NOT GENERIC.
That’s the heart of Eagle Bay. A large coastal house can easily tip into too formal, too complex, too heavy. This one takes a calmer path: the planning stays clear, the spaces feel generous, and the connection to the site does the heavy lifting.
The home opens toward the landscape while the interiors stay light, calm and unfussy — spacious without ever being loud. It has genuine architectural presence, but the focus stays where it belongs: on family, place and everyday comfort. Scale, with the relaxed spirit of a shack intact.
THE MIDS BENEFIT.
Eagle Bay shows how MIDS creates a generous, site-specific holiday home without starting from a blank page. Through Map iT and the Shack Map, the brief gets tested early using predefined modular zones — how much house is really needed, how many sleeping zones make sense, how much outdoor area is useful, where family and guests gather, and what the site, budget and builder can realistically carry.
That early testing matters, because budget blowouts usually start early, when a project races into full design before scope, scale and site conditions have been properly examined. MIDS brings discipline to that stage — a clearer starting point for client and architect before the project gets too expensive to question. After that, the build method follows the project: in-situ, prefab or hybrid. The benefit, as always, is structure without sameness.
BUDGET GUIDE.
Eagle Bay is a generous, customised coastal home, so think of its build cost as a band rather than a single figure. As an indicative guide, a comparable Eagle Bay holiday home of this scale would sit in the range of $2.5–3.0 million to build, depending on floor area, specification, site complexity and approval pathway. That excludes land, consultant and approval fees.
On an elevated coastal site, the cost drivers are real — slope, access, wind, coastal exposure, services, selections, external works and builder availability all move the number. That’s exactly why early budget testing matters. A Map iT and Shack Map won’t replace builder pricing or consultant input, but they give the project a disciplined starting point — and a realistic band — before design, documentation, approvals and pricing firm it up.
