Luxury Custom Home Builder Mornington Peninsula

Bespoke luxury homes, knock down rebuilds, and developments — designed and built end-to-end by one director-led team, for 18+ years.
Boutique Luxury Building

Bespoke homes.
Uncompromising standards.

NB Custom Builds specialises in luxury custom homes on the Mornington Peninsula’s best-positioned blocks — architecturally designed, premium-specified, and personally supervised from concept to handover. We also deliver knock down rebuilds, duplex developments, and sustainable builds for clients across the Peninsula, all to the same standard.

Director Nick Barbera is your single point of contact throughout. We take on a limited number of projects each year, by design, so every build gets the craftsmanship a luxury home demands.

NB Custom Builds. Built on the Peninsula. Built to last.

Why NB Custom Builds

What makes the difference on every build.

01Nick Barbera, Personally

Nick — Managing Director — is on every project himself, not a rotating project manager. You call him directly, start to finish.

02Registered & Licensed

Registered Builder VIC, Master Builders Victoria member, 18+ years working with Mornington Peninsula Shire Council.

03A Limited Number of Builds

We deliberately take on fewer projects each year than most builders, so a luxury build gets director-level attention throughout.

04One Contract, One Builder

Design, permits, construction, and handover are all managed in-house — no handoffs between separate contractors.

Nick Barbera — Director & Builder
Director-led. Peninsula-rooted.

Meet the builder behind every project.

Nick began as a carpenter, learning his craft on the tools, before becoming a project manager for one of the Peninsula’s most prominent builders. He founded NB Custom Builds to deliver luxury homes that exceed expectations — personally leading every project himself, from the first site visit to final handover.

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

Typical inclusions

Knock Down Rebuild

A knock down rebuild lets you start fresh on a block you already love. We manage the entire process under one roof — permits, demolition, design, and construction — so you’re never juggling separate contractors. One builder, one relationship, one standard of quality.

The Process

Duplex Developments

For blocks with subdivision potential, we design and build dual-occupancy developments that maximise site value — whether you’re planning to sell, rent, or keep both dwellings in the family. Feasibility is assessed honestly before any design work begins.

Typical inclusions

Sustainable Home Build

Passive solar design, double-glazing, and energy-efficient specifications are central to building well on the Peninsula’s coastal-adjacent climate — reducing running costs and improving comfort year-round, without a generic “eco” premium tacked on.

Typical inclusions

Sloping Block Build

Rather than engineering around a sloping block, we design to embrace it. Split-level layouts, engineer-certified footings, and considered retaining design turn a difficult site into a standout home — usually with better views than a flat block could offer.

What sloping blocks require

Passive House Construction

A Passive House is a tested performance standard, not a marketing term. We design and build to meet it — verified by modelling and airtightness testing before handover, not just described as “eco” on a brochure.
