Double your living space without sacrificing your backyard. Belvedere Building & Electrical builds fully engineered, council-approved second storey extensions across Newcastle, Lake Macquarie and the Hunter Valley.
Land in Newcastle is too valuable to give away. A second storey extension is one of the smartest investments a homeowner can make — doubling your usable floor area, dramatically increasing your property value, and preserving every square metre of your outdoor space.
Belvedere Building & Electrical has built second storey additions across Newcastle, Lake Macquarie and the Hunter Valley for over a decade. Led by brothers Vincent and Clarence Quin, our licensed team manages every stage — structural engineering, council approvals, framing, roofing, insulation, electrical, internal fit-out and final render or cladding. One team. One contract. No confusion.
From structural engineer engagement through to council DA or CDC lodgement — we manage every approval so you can focus on the design and the result, not the paperwork.
A second storey is a major investment. We provide a fully detailed, fixed-price contract before work begins — no budget blowouts, no surprise variations once the build is underway.

The most common questions Newcastle homeowners ask before committing to a second storey build.
Ask Us DirectlySecond storey extension costs in Newcastle typically range from $180,000–$350,000+ depending on the size of your home's footprint, the complexity of the structural work, number of rooms, wet areas and the level of finish selected. A partial second storey over a garage or rear wing can start from $120,000. We provide a detailed fixed-price quote after a free site assessment — contact us today.
Yes. Second storey additions require either a Development Application (DA) or Complying Development Certificate (CDC) depending on your property's zone, size and location. In many cases a CDC is faster and avoids formal council submission. We assess your property at the consultation stage, advise the best approval pathway and manage the entire lodgement process for you.
From design through to Occupation Certificate, most second storey extensions in Newcastle take 9–14 months. This includes design and engineering (4–8 weeks), approval (6–12 weeks for DA, 2–4 weeks for CDC) and construction (4–6 months). We provide a clear project schedule at the quoting stage so you can plan accordingly.
In most cases, yes. We stage the build to minimise disruption to the ground floor — the most disruptive phase is typically when the existing roof is removed and temporary weatherproofing is installed. We protect your living areas throughout and keep you informed of any periods where access will be more restricted. We'll advise you honestly at the consultation stage.
Most brick veneer and timber-frame homes in Newcastle can support a second storey with the right structural engineering and footing upgrades. Slab-on-ground homes, heritage-listed properties and some older constructions may have limitations. Our structural engineer assesses every home before we quote — so you get an honest answer about what's possible before committing to anything.
