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.
NB Custom Builds. Built on the Peninsula. Built to last.
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.
We design and build custom homes across the full spectrum of Mount Martha’s residential market — from luxury coastal retreats to precision knock down rebuilds.
Our services in Mount Martha include:
Each service is delivered with the same standard of craftsmanship and personal involvement from first concept to handover.
Mount Martha’s residential landscape is as varied as its terrain. We build across all of these home types:
Coastal luxury homes: Architecturally designed residences that make the most of Port Phillip Bay views, outdoor living, and the coastal light. Open plan, raked ceilings, and premium material selection.
Hillside and sloping block builds: Mount Martha’s upper streets present some of the Peninsula’s most challenging terrain. We specialise in split-level and basement-integrated designs that turn a difficult block into a standout home.
Knock down rebuild: Many of Mount Martha’s older Weatherboard and brick homes sit on exceptional blocks ready for a new chapter. We manage the full KDR process — permits, demolition, and build.
Dual occupancy: For larger blocks with subdivision potential, we build dual-occupancy residences that maximise the site value.
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.
Coastal wind and salt exposure: Material selection matters here. Double-glazed windows, treated cladding, and corrosion-resistant fixtures are standard in our coastal build specifications.
Mornington Peninsula Shire planning: Many Mount Martha blocks fall under Bushfire Attack Level (BAL) overlays and coastal management zones. 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.
Two Bays Residence — Mornington Peninsula: A contemporary coastal build on a dual-aspect block. Designed to capture bay views from every living space with raked ceilings, a frameless glass deck, and a passive solar orientation.

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.
If you’re planning a custom home, knock down rebuild, or renovation in Mount Martha, we’d love to hear about your project.
