Narrow-Lot Home in Preston, Inner Melbourne
A narrow-lot home is designed for blocks under 10 metres wide. Melbourne has thousands of these blocks, especially in inner suburbs where old quarter-acre blocks have been split. The design constraints are unforgiving, but the right builder can deliver 4 bedrooms and a double garage on 7 metres of frontage.

Council rules and overlays for narrow-lot home in this area
In Victoria, a new build generally needs a planning permit (where the local planning scheme requires one) and a building permit issued by a registered building surveyor. Overlays such as Bushfire Management, Heritage, Significant Landscape and Development Contributions can apply, and growth-area blocks may attract the Growth Areas Infrastructure Contribution (GAIC). Confirm current requirements with your local council and the Victorian Building Authority before finalising a design.
The 3 decisions that shape your narrow-lot home in Preston
Garage placement
A tandem garage keeps the frontage clean but uses depth. A side-by-side double eats frontage. On a narrow lot, this decision drives every other design choice.
Boundary walls
Building on the side boundary (nil setback) gives you the most usable width. It requires a boundary wall agreement with the neighbour and a fire-rated wall spec.
Natural light
A 7-metre wide house has a middle zone with no external walls. Voids, skylights, courtyards and clever floor plans matter here more than anywhere.
Narrow-Lot Home FAQs for Preston
What is the minimum block width for a house?▾
It varies by council. Charles Sturt allows homes on blocks as narrow as 6 metres in some zones. Others require 7.5 metres or more. Check your specific zone.
Can I build a double garage on a 7-metre frontage?▾
A side-by-side double garage is 5.4 to 6 metres wide, leaving little for anything else. A tandem garage is usually the right answer on frontages under 8 metres.
Do I need a boundary wall agreement?▾
Only if you build directly on the shared side boundary. This is usually written between property owners and lodged with council.
Are narrow-lot homes harder to sell?▾
In inner-suburb Melbourne there is strong demand for well-designed narrow-lot homes. Elsewhere they can be harder to shift because the buyer pool is smaller.
Can I get a project-builder design for a narrow lot?▾
A handful of project builders offer narrow-lot ranges. Custom builders handle it better because every narrow lot has different constraints.
