Know Your Home
Can Your Home Be Extended Upwards?
The right way to add space depends on how your home is built. Here's how we typically approach the most common Sydney home types — a free on-site assessment confirms the best solution for yours.
Victorian Terraces
Second Storey ExtensionNarrow rooflines rarely suit a full attic conversion, so a carefully designed second storey addition set behind the parapet is usually the best way to add bedrooms while protecting the heritage streetscape.
Federation Homes
Attic Conversion or Roof LiftTheir steep pitched roofs often hold generous volume, making attic conversions ideal. Where headroom is tight, a roof lift creates full standing height without a complete second storey.
Semi-Detached Homes
Second Storey ExtensionShared walls and compact blocks mean building up is often the only practical option. An engineered second storey adds real space while keeping your courtyard intact.
Freestanding Homes
Attic Conversion or Second StoreyThe most flexible of all. Depending on your roof pitch and goals, either an attic conversion or a full second storey extension can work beautifully.
California Bungalows
Roof Lift or Attic ConversionTheir broad, low-pitched roofs usually need a roof lift to achieve comfortable ceiling height, unlocking a light-filled upper level in keeping with the home's character.
Modern Brick Homes
Second Storey ExtensionTrussed roofs leave little usable attic space, so a second storey extension is typically the most effective way to add bedrooms, bathrooms and living areas.

This isn't a sideline for us. Every day, on every job, we're building above Sydney homes — nothing else.
We understand Sydney roof structures
Federation gables, terrace roofs, brick bungalows — we know how Sydney homes are built and how to open them up safely.
We manage every approval
From exempt development to full DA submissions, we handle councils and certifiers so you don't have to chase paperwork.
We minimise disruption
We work from the roof space wherever possible, so your home stays liveable and your family stays put throughout the build.

- Clever hidden storage
- Custom-built staircase

- Increased property value
Meet the Founder
Built on craftsmanship, run like family
Matt started converting Sydney attics more than a decade ago with a simple belief: the space above your home should be as considered and beautifully built as the rooms below it.
Since then, the team has completed thousands of conversions across the city — from compact storage rooms to full light-filled bedrooms and offices. Matt still personally reviews every design, so the care that started it all carries through to your home.
“We treat every attic like it's our own home. That's the only standard worth building to.”
Loved by Sydney homeowners
We were impressed with the speed and efficiency of the entire process. Matt's team did everything possible to accommodate our requests. The work crew did a great job and no detail was spared — considerate about cleaning up and noise levels too.
Dave & Val Melvin
Google Review
Matt and his team were sensational. Every aspect was dealt with professionally, from quoting through to the finish. The dust-proof attic room they created gives us incredible access to 15sqm of light-filled space. It feels more like a loft than an attic!

FAQ
Answers to common questions
Still have questions? We're happy to talk it through during your free on-site inspection.
Book a free inspectionHow much does an attic conversion cost in Sydney?
Costs vary with size and scope. Dust-free storage rooms start from around $10,000, premium utility rooms typically range from $60,000 to $100,000, and full DA-approved conversions with bedrooms and bathrooms range from $120,000 to $200,000+. We provide free on-site inspections and detailed, fixed quotes.
Do I need council approval (DA) for an attic conversion?
It depends on the scope. Many storage rooms and utility spaces qualify as exempt development and don't require a DA. Adding bedrooms, bathrooms or significant structural changes usually does. We handle the entire approval process for you.
How long does an attic conversion take?
Premium utility rooms are typically completed within 4-6 weeks. Full DA-approved conversions take 8-12 weeks depending on complexity. We remain on-site throughout with minimal disruption to your daily life.
What areas of Sydney do you service?
We service the Inner West, Eastern Suburbs, North Shore and greater Sydney — including Marrickville, Ryde, Bronte, St Peters, Drummoyne, Bexley North, Randwick and surrounding areas.
