Add the space you need without moving. We plan, design and build seamless extensions that feel original to your home—handling approvals, engineering and construction with care.
We offer
Custom extension types we build
Upper-storey additions
Gain extra bedrooms, a parents’ retreat or flexible living upstairs with careful planning for structure, services and stairs.
Heritage-listed homes
Sensitive design and detailing that respects original character while improving comfort, function and everyday liveability.
Why extend with us
Specialists in combining function and style
Maximise your space
Smart layouts that add the right kind of room—living, bedroom wings or upper-storey additions—so your home works better day to day.
Seamless inside and out
We match rooflines, cladding and windows so the extension feels like it was always part of the home—cohesive, not tacked on.
Comfort and performance
Upgraded insulation, glazing and services improve thermal and acoustic comfort while keeping running costs sensible.
Planning & approvals
A clear, ACT‑ready approvals pathway
We simplify feasibility, the right approval route and building certification—so your extension moves forward with confidence.
1. Feasibility & site checks

Feasibility & site checks
We start with your wish list and a site review—checking zoning, lease conditions, setbacks, easements and site coverage. You’ll get clear options before committing.
ACT specifics: we consider Territory Plan controls, overlays (heritage/bushfire/flood) and solar access.
2. Survey, concept & energy strategy

Survey, concept & energy strategy
We coordinate a detail survey and measure-up, then sketch concepts that maximise flow and light. Early energy decisions (insulation, glazing, orientation) keep comfort and costs in balance.
NCC 2022-compliant fabric upgrades are planned practically for extensions, not just new builds.

Choose the approvals pathway (ACT)
Many minor additions can be exempt or code-compliant. Larger works, heritage or sensitive sites usually need a Development Application (DA) with public notification.
We advise the simplest compliant route and prepare what’s needed for either exempt pathways or DA.
4. Documentation & DA lodgement

Documentation & DA lodgement
We prepare drawings, reports and statements for ACT Planning and lodge the DA (if required). Timeframes vary—allow roughly 4–8 weeks depending on complexity.
We handle queries and requests for information so assessment stays on track.

Building approval with certifier (BA)
After planning approval (or for exempt works), a licensed ACT building certifier issues the Building Approval. Structural engineering and energy documentation are bundled here.
We coordinate BA submission and responses so you’re ready to build.

Construction & inspections
Our tidy, respectful team builds your extension with weekly updates. The certifier completes mandatory stage inspections to keep quality and compliance tight.

Design integration
Extensions that belong—inside and out

Budget & inclusions
What influences extension costs?
Typical cost drivers
- Structural complexity: spans, steel, tie-ins to existing roof and walls
- Site access, foundations and services relocation (plumbing, electrical)
- Glazing area and performance, insulation upgrades and energy strategy
- Kitchen, bathroom and joinery specifications and quantity
- Cladding, windows/doors, flooring and external works/landscaping
Transparent allowances
We outline inclusions and exclusions early, using sensible Prime Cost and Provisional Sums so you can compare options with confidence.
