About Majestic
Granny Flats

Built on Trust. Backed by Experience.

We design and build granny flats, studios, linked extensions and new homes for families right across Australia. Every project runs on a fixed price, a fixed program and a materials list chosen for Australian conditions — so you know what you're getting before the slab goes down.

The result is a home that's quicker to build, cheaper to run, and backed by a 25-year structural guarantee.

Our Values

Built on Trust.
Backed by Experience.

A granny flat is a big decision for a family — often for a parent moving closer, or an investor adding a second income. Four principles decide how we quote, how we build, and what we hand over.

V—01

Integrity

Fixed-price contracts and an itemised scope before you sign. If something changes on site, you hear it from us first — with the cost, in writing.

V—02

Innovation

Engineered framing, prefinished panels and a sequenced trade program. Better design and smarter methods are why our builds finish faster.

V—03

Sustainability

Responsibly sourced timber, high-performance wall systems and orientation-led design that cuts heating and cooling costs for the life of the home.

V—04

Excellence

Licensed, long-standing trades and staged quality checks at frame, lock-up and handover. We hand over homes we'd put our own family in.

Our Sustainable Approach

Built for Comfort and Sustainability

Materials aren't a line item — they decide how the home feels in February, what it costs to run, and how it looks in twenty years. Here's what we specify as standard, and why each one earns its place in an Australian build.

M-01 · Glass

Double glazingBright, Open & Connected

Large, thermally broken glazing placed to catch northern light and frame the garden. Double-glazed units keep the warmth in through winter and the heat out through summer, without shrinking the windows.

M-02 · Hebel®

Aerated concrete panelQuiet, Strong & Energy-Efficient

Hebel® panel gives you solid masonry walls with real thermal mass and a noticeable drop in road and neighbour noise. It's light enough to go up fast and non-combustible where bushfire ratings apply.

M-03 · Fibre Cement

James Hardie™Durable & Architecturally Versatile

Engineered for Australian conditions — resistant to moisture, termites and warping. Wide boards, fine boards or flat sheet with express joints let us match a heritage street or go fully contemporary.

M-04 · Steel Roofing

Colour-coated steelSleek, Strong & Built for Australian Conditions

Steel sheds heavy rain, handles coastal wind and won't crack under a 40-degree week. The skillion profile keeps the roofline low for council, lifts internal ceilings, and takes solar without extra framing.

M-05 · Timber Framing

Certified plantation stockReliable, Efficient & Responsibly Sourced

Precision-cut frames from certified plantation timber arrive ready to stand. Less waste on site, a straighter build, and a renewable structure that stores carbon rather than emitting it.

M-06 · Summary

Why It MattersThe Payoff, Year After Year

  • Lower power bills from day one
  • Stable temperatures, less noise
  • Low-maintenance exteriors
  • Stronger resale and rental appeal

Processes & Expert Trades

Licensed trades we've worked with for years, checked at every stage against a documented build standard.

  • Structural failure of footings, slab, load-bearing walls, roof trusses and framing.
  • Defects in workmanship reported within the defect liability period.
  • Materials supplied by us that fail within their manufacturer warranty period.
  • Waterproofing to wet areas installed under our contract.
  • Rectification labour, materials and site attendance for any covered claim.
  • Normal wear and tear, fading, and settlement cracking within accepted tolerances.
  • Damage from storm, flood, fire, earth movement or other events covered by home insurance.
  • Work by others, owner-supplied items, or alterations made after handover.
  • Failure to carry out routine maintenance, including gutter and drainage upkeep.
  • Landscaping, driveways and external works outside our contracted scope.

The guarantee begins at practical completion and applies to the original owner. Claims must be lodged in writing so we can inspect before any rectification. Our guarantee sits alongside — and does not limit — your rights under the Australian Consumer Law and applicable state building legislation.

Full terms are set out in your building contract. Ask us for a copy at quote stage, not after signing.

Why Choose Us

Built on Trust.
Backed by Experience.

Plenty of builders can put up a granny flat. Fewer can tell you the price on day one, the date you'll get the keys, and still be answerable to you five years later. That's the difference we sell.

Whether it's a studio for a parent, a linked extension for a growing family, or a new home from the ground up — the process, the pricing and the guarantee stay the same.

  • Faster constructionPrefinished panels and a sequenced trade program put most granny flats at handover in 14–18 weeks from slab.
  • Better designsIn-house designers work to your block, your setbacks and your northern light — not a catalogue plan dropped on site.
  • Built for Australian conditionsMaterials and detailing chosen for heat, coastal wind, bushfire ratings and long dry summers.
  • A transparent processFixed price, itemised inclusions, and a single point of contact from first sketch through to handover.
  • Guaranteed for 25 yearsA structural guarantee, HIA indemnity insurance and a defect liability period that we honour without argument.

Our Story

Brickox started in 1978 in a modest suburban Chicago shop. Four staff, a few carpenters, two tables, and a sanding machine. What fueled us was drive, dedication, energy, and vision.

Twenty years later, Brickox expanded into a comprehensive construction and contracting team spanning 15 states. Beyond constructing buildings, we craft environments where people can excel and innovate. Our core strength is listening, visualizing, and executing with precision.

To deliver results, we develop personalized solutions for construction, expansion, and remodeling projects. With a skilled in-house team and trusted network of specialists, we provide creativity, cutting-edge technology, and quality materials. Each project is an opportunity to bring a client’s vision to life in remarkable environments.

By 1985, Brickox had outgrown its original suburban workshop. Rising demand led to a move into a larger Chicago facility, allowing the company to scale operations and take on more ambitious projects. This expansion marked a shift from small-scale builds to structured construction planning.

Brickox implemented formal systems and secured its first multi-building projects, proving its ability to manage complex builds.

Brickox also established lasting client relationships, trusted supplier networks, and in-house training programs. The leadership culture formed in 1985 hands-on, precise, and forward-thinking became the backbone of its continued growth and reputation across regions.

In 1998, Brickox transitioned into strategic growth, expanding operations, upgrading equipment, and adopting advanced construction methods to meet increasing demand.

Brickox invested heavily in modern project planning tools, scheduling systems, and on-site coordination practices. These improvements increased efficiency, reduced risk, and ensured greater control across multiple active projects, setting new internal benchmarks for delivery and performance.

By 1998, Brickox was known for reliability, precision, and collaboration. Long-term partnerships grew, repeat clients increased, and the company’s reputation as a trusted construction partner was firmly established for future multi-state success.
