Custom New Homes

Every custom home we build is designed around the people who live in it. We take the time to understand your lifestyle, block, and long-term goals, creating homes that feel personal, practical, and timeless.

From layout planning to finishes and detailing, your home is built with quality materials, smart design, and craftsmanship that stands the test of time.

Architectural Renovations

Whether you’re transforming an existing home or adding new spaces, our architectural renovations enhance both form and function.

We specialise in:

  • Structural renovations

  • Extensions and additions

  • Reconfiguring layouts for modern living

Each renovation is carefully integrated into your existing home for a seamless, cohesive result.

Duplex & Dual Occupancy Builds

For families, developers, or investors, JMAR Building Co delivers well-considered duplex and dual occupancy homes that maximise space without compromising comfort or quality.

Our builds focus on:

  • Smart layouts

  • Natural light and flow

  • Practical, low-maintenance finishes

The result is homes that feel spacious, functional, and built for long-term value.

Kitchens & Bathrooms

Kitchens and bathrooms are some of the most used spaces in any home — and they need to work beautifully.

We design and build kitchens and bathrooms that combine:

  • Thoughtful layouts

  • Quality materials

  • Durable finishes

  • Practical storage solutions

The outcome is spaces that are functional, stylish, and built to last.

Our commercial fit-out services are tailored to businesses that value efficiency, durability, and design.

We work closely with business owners to create spaces that:

  • Improve workflow

  • Reflect brand identity

  • Balance function and visual appeal

From planning through to completion, we deliver fit-outs that support your business long-term.

Outdoor Living & Carpentry

Outdoor spaces should feel like a natural extension of your home. From decks and pergolas to custom carpentry, we build outdoor areas designed for entertaining, relaxing, and everyday use.

Our carpentry services focus on:

  • Quality construction

  • Materials suited to the local climate

  • Clean detailing and long-term durability
