Custom Home Builder Mount Martha

Boutique builds designed for coastal living on the Mornington Peninsula.
01 — Introduction
Building in Mount Martha

Built for the
Peninsula.

Mount Martha is one of the Mornington Peninsula’s most sought-after coastal suburbs — a location defined by hillside blocks with sweeping Port Phillip Bay views, tree-lined streets, and a relaxed yet refined lifestyle. For families upgrading their forever home or homeowners looking to knock down and rebuild, Mount Martha offers something rare: the space, the views, and the community of a coastal village within an hour of the CBD.

At NB Custom Builds, we’ve been building on the Mornington Peninsula for over 18 years. We understand the terrain, the council requirements, and the architectural character that makes Mount Martha homes so distinctive. Whether you’re building on a sloping coastal block, designing around Port Phillip Bay views, or rebuilding on an established street, we bring the same boutique approach and personal involvement to every project — from the first site visit to final handover.

Why Mount Martha
Homeowners
Choose Us

Building a custom home is one of the largest decisions you’ll make. Choosing the right builder determines whether it’s a process you enjoy — or one you endure.

Nick Barbera has personally led every NB Custom Builds project for over 18 years on the Mornington Peninsula. That means when you call, you speak to the director. When a decision needs to be made on your build, it doesn’t wait for a meeting — it gets handled.

We work with Mornington Peninsula Shire Council regularly and understand the planning overlays, BAL ratings, and coastal design requirements specific to Mount Martha and surrounding suburbs. Our boutique approach means we take on a limited number of builds each year — ensuring your project gets the time, attention, and craftsmanship it deserves.

No volume. No shortcuts. Just quality custom building, delivered personally.

Sloping terrain is common in upper Mount Martha, and it’s something we have extensive experience with. Our approach includes engineer-certified footing design, split-level floor plans that reduce cut-and-fill, and basement integration where appropriate.

Rather than engineering around a sloping block, we design to embrace it. The result is usually a better home with better views.

Understanding Mount Martha's
Blocks & Environment

Building in Mount Martha requires more than standard residential construction knowledge. The suburb’s hilly terrain, coastal exposure, and council overlays create a specific set of design and engineering requirements — and we’ve been navigating them for nearly two decades.

Sloping Terrain

Upper Mount Martha streets feature significant fall, requiring engineer-certified footings, retaining wall design, and in some cases, basement integration.

Footings Engineer-certified footing design required on most hillside blocks. We identify soil conditions and slope early in the site assessment.
Design Split-level floor plans reduce cut-and-fill and produce homes that sit naturally in the landscape — not against it.
Views Sloping blocks, designed well, produce the best views. We orient every floor plan to maximise Port Phillip Bay sightlines.

Coastal Wind & Salt Exposure

Material selection matters here. Double-glazed windows, treated cladding, and corrosion-resistant fixtures are standard in our coastal build specifications.

Cladding Treated fibre cement or engineered timber specified for salt-air environments. Untreated timber is not recommended on coastal facades.
Windows Double-glazed with thermally broken aluminium frames — standard for both coastal wind performance and energy efficiency.
Roofing Colorbond or zinc roofing systems recommended. Terracotta is suitable on more sheltered blocks.

Mornington Peninsula Shire Council

Many Mount Martha blocks fall under specific planning overlays — NB Custom Builds provides permit advisory as part of our service. We know what Mornington Peninsula Shire requires, and we make sure your project meets it.

Permits Planning permits required in addition to building permits on many blocks — particularly near coastal reserves and management zones.
Overlays Coastal management zones, vegetation overlays, and design guidelines apply across parts of the suburb. We identify these at site assessment.
Advisory NB Custom Builds handles council liaison and permit advisory — you don't need to navigate Mornington Peninsula Shire alone.

Bushfire Attack Level Ratings

Some Mount Martha properties — particularly near the escarpment fringe and coastal reserves — fall under BAL overlays requiring specific material specifications.

Assessment We identify BAL requirements during site assessment — before design begins. No surprises mid-build.
Materials BAL-compliant specifications for windows, doors, decking, and roof penetrations are included from day one.

Mount Martha's Local Character

Mount Martha is defined by its hillside coastal setting, Port Phillip Bay views, proximity to Balcombe Grammar, and a relaxed but refined community character attracting families, professionals, and downsizers alike.

Style Coastal contemporary, Hamptons-influenced, and modernist styles all suit Mount Martha's character and perform well in the local market.
Schools Proximity to Balcombe Grammar, Toorak College, and Peninsula Grammar makes Mount Martha one of Victoria's most family-oriented coastal suburbs.
Market Quality custom builds in Mount Martha command premium resale prices — making your builder choice a long-term financial decision.

Questions

Everything you need to know about building a custom home in Mount Martha — from permits and council requirements to costs and home styles.

Do you build custom homes in Mount Martha?

Yes — Mount Martha is one of our core service areas on the Mornington Peninsula. We’re based in Dromana and travel across the full Peninsula for projects.

Mount Martha’s coastal character suits a range of architectural styles — from coastal contemporary (open plan, passive solar, raked ceilings) to Hamptons-influenced designs popular in the suburb’s established streets. Hillside blocks in upper Mount Martha suit split-level and elevated designs that maximise Port Phillip Bay views. We work with you to design a home that responds to your specific block, aspect, and lifestyle.

Sloping terrain is common in upper Mount Martha, and it’s something we have extensive experience with. Our approach includes engineer-certified footing design, split-level floor plans that reduce cut-and-fill, and basement integration where appropriate. Rather than engineering around a sloping block, we design to embrace it — the result is usually a better home with better views.

Building in Mount Martha falls under Mornington Peninsula Shire Council jurisdiction. Depending on your block, you may require planning permits (in addition to building permits), Bushfire Attack Level (BAL) assessments, and compliance with coastal management overlays. NB Custom Builds provides permit advisory as part of our pre-construction process — we handle the paperwork and council liaison so you don’t have to.

The cost of a custom home depends on a range of variables: size, specification level, site conditions, slope, and finish quality. Rather than give a figure that may not reflect your project, we prefer to discuss your specific block and brief in a consultation. Book a call with Nick to get an honest, realistic picture of what your build will cost.
