Home Extensions in Devonport
Single-storey and second-storey additions, deck and studio builds, and outdoor living extensions across greater Devonport and the Don Valley. Design and construction under one roof.
Extending Devonport Homes — Design & Build Since 2009
Devonport is one of Tasmania's fastest-growing regions, and many families who moved here for the lifestyle are now outgrowing their homes. Whether you need another bedroom for a growing family, a larger open-plan living area, a home office that functions as a proper workspace, or an outdoor room that connects to the garden — extending your existing Devonport home is often more affordable and far more satisfying than selling and buying again.
Davies Design & Construction provides end-to-end extension services across greater Devonport and the Don Valley. Our design-build model integrates Align Architecture & Interiors — our in-house architecture firm, founded by Luke Davies — with our construction team. Your architect and builder are the same people from brief to handover, which means one accurate cost, one point of contact, and one accountable team throughout.
We've delivered award-winning homes across the Devonport region — from coastal builds at Hawley Beach and Port Sorell to properties in Spreyton and Latrobe. That means we understand how Devonport homes sit on their blocks, how the coastal climate affects building design, and what Devonport City Council requires for extension approvals. Local knowledge that saves you time and money at every stage.
Every Davies extension is also an opportunity for a genuine performance upgrade. With Passivhaus-informed insulation, double glazing, and airtightness, a new extension can transform how comfortable your existing home feels — setting a new thermal standard that the rest of the house will eventually rise to meet.
Extension Types We Build in Devonport
Single-Storey Extensions
Rear and side extensions that expand the ground floor — new living rooms, bedrooms, kitchens, or utility spaces. The most common extension type in Devonport, offering high impact for the cost.
Second Storey Additions
Adding a full second storey or partial upper level dramatically increases floor area without expanding the footprint — ideal for Devonport blocks where the garden is a priority.
Studio & Granny Flat Additions
Self-contained studio, home office, or secondary dwelling — attached or separate. Adds rental income potential, multi-generational living flexibility, or a properly functioning work-from-home space.
Deck & Alfresco Extensions
Outdoor rooms designed for Devonport's climate and coastal lifestyle — covered decks, alfresco dining areas, and verandahs that extend your living space into the garden.
Building Envelope Upgrades
Super-insulation, airtightness improvements, and double glazing retrofits. Often combined with an extension to deliver a whole-home performance transformation in a single project.
Design-Build Service
Architecture, interiors, and construction under one roof. Align Architecture & Interiors works alongside our build team from day one — one budget conversation, one team accountable for the result.
Extending in Devonport — What You Should Know
Devonport's planning environment has specific factors that affect extension projects. We surface these before design begins so there are no mid-project surprises:
- Permitted development standards: Extensions within the Tasmanian Planning Scheme's Permitted thresholds — covering setbacks, height, and site coverage — don't require a planning permit. We determine your project's category before the design process begins, which affects timeline and cost.
- Coastal overlay areas: Properties near East Devonport, the Don River foreshore, Hawley Beach, and Port Sorell may be subject to coastal hazard overlays and setback requirements from Devonport City Council. We identify these at the feasibility stage.
- Basalt geology in elevated areas: Parts of Stony Rise, Miandetta, and elevated Devonport sites sit on basalt — which may require rock excavation for footings. We assess site conditions early so foundation costs are factored into your budget from the start.
- Bushfire Attack Level: Some rural and fringe properties around Latrobe, Spreyton, and the Sheffield corridor require BAL assessment — this affects cladding and glazing specification for extensions as much as new builds.
- Spirit of Tasmania precinct works: If your Devonport property is near the port redevelopment area (2026–27), check council requirements around construction staging and access during the works period.
