Service
Home Extensions & Additions in Newcastle
Ground floor, rear and second-storey extensions that tie into your existing home without looking bolted on.
Adding to a home you already live in is harder than building new. The structure has to tie into what is already there, the roofline has to read as one building, and you have to keep living in the house while it happens. We stage the work so your kitchen and bathroom stay usable for as long as possible, and we seal the opening before we cut into it.

- Ground floor and rear extensions
- Second-storey additions and lift-ups
- Structural steel and load-bearing wall removal

FAQ
Extensions & Additions questions
Do I need council approval for a home extension in Newcastle?
Most extensions need either a Complying Development Certificate or a Development Application through Newcastle City Council or Lake Macquarie City Council. We will tell you which path your job falls under at the quote stage and work with your certifier or draftsperson to get it lodged.
Can I stay in the house during the build?
Usually yes. We stage extensions so the existing house stays weather-tight and your kitchen and bathroom remain usable for as long as possible. We seal off the work zone with dust protection before any demolition starts.
How long does a home extension take?
A single-room ground floor extension typically runs 8 to 12 weeks on site. A second-storey addition is more often 4 to 6 months. Weather, council approvals and material lead times all move that, and we give you a written program before we start.
