Services

Earth-Sheltered, Bushfire & Storm-Resilient Architecture

We design homes and places that work with the land—taking advantage of earth-sheltering, thermal mass and smart detailing to create quiet, efficient, resilient buildings. From concept to approvals and construction documentation, our service is end-to-end.

Earth-sheltered residence integrated into the landscape
Earth-Sheltered Homes

Low-profile forms, high thermal performance, naturally protected from wind and heat. Daylight and ventilation planned from first principles.

Site Analysis Concept Design Approvals Documentation
Bushfire-conscious architecture
Bushfire-Responsive Design

Siting, materials and detailing to reduce risk exposure and improve performance across BAL contexts (general guidance; site-specific assessment required).

BAL Strategy Envelope & Cladding Openings & Shading Landscaping Interface
Coastal home with robust storm detailing
Storm & Weather Resilience

Robust rooflines, drainage, anchoring, and material selections for coastal and upland conditions. Practical detailing for long-term durability.

Approach

Design that’s responsive, efficient, and grounded in place

Site-first thinking

We start with orientation, topography, soil/rock, climate and view corridors—then fit form to context, not the other way around.

Thermal mass & daylight

Correct use of mass, insulation and glazing delivers consistent comfort with low operational energy.

Buildable detailing

We prioritise details that are practical on-site, robust in harsh weather, and maintainable over decades.

How it works

A clear path from first sketch to keys

Discovery & Site Read

We workshop your goals, constraints, and site nuances. Early advice covers orientation, massing, access, and BAL context (if applicable).

Concept & Options

Multiple options exploring earth coverage, daylighting, courtyards, and view framing. We test practicality and budget alignment early.

Design Development

Structure, envelope, openings and services coordinated; preliminary detailing for bushfire/weather performance and ongoing maintenance.

Approvals & Documentation

We prepare documentation for approvals and tender, coordinating consultants and reports required for your jurisdiction.

Construction & Review

We support procurement and construction with site queries, detail clarifications, and review checkpoints to keep quality on-track.

Performance

Comfort by design, resilience by default

Thermal mass + insulation

Stabilise indoor temperatures with tuned mass, insulation continuity, airtightness, and solar control.

Daylighting & ventilation

Bring in sky and horizon while protecting from heat and smoke; cross-ventilation paths planned from the outset.

Weathering & maintenance

Details, materials and junctions selected for longevity, easy maintenance, and lifecycle value.

Compare

Earth-sheltered vs conventional — at a glance

Aspect Earth-Sheltered Conventional
Thermal stability Excellent (mass + earth) Variable; relies on insulation/HVAC
Wind & storm exposure Reduced profile Higher profile, more exposed
Acoustic buffering High Moderate
Site integration Embedded, landscape-led Above-grade, landscape follows
Complexity Requires specialist design Widely standardised

Case studies

Proven outcomes in varied landscapes

From coastal headlands to bush settings, each build shows how low-profile forms, massing and openings work together.

FAQ

Common questions

Will an earth-sheltered house feel dark?

Not if planned correctly. We use daylight scoops, courtyards, clerestories and optimised glazing to pull light deep into the plan while managing heat gain.

How do you manage drainage and moisture?

Layered waterproofing, positive drainage planes, perimeter drains and robust detailing. We simplify maintenance and design for inspection access.

What about bushfire requirements?

We develop a site-specific strategy considering BAL context, vegetation, siting, materials and ember protection. Your final approach is coordinated through approvals.

Is it more expensive than conventional?

It depends on site and scope. We discuss budget early and design for value, prioritising where performance has the biggest impact.

Do you work outside NSW?

Yes, subject to project suitability and local approvals. Let’s discuss your site and program.

Can you help with builders and tendering?

Yes—we prepare documentation, coordinate consultants and support tendering and construction with timely clarifications.
