How to Knockdown and Rebuild on a Narrow Lot in Sydney – A Real Project Breakdown
If you've been living in an ageing home on a narrow Sydney block, you've probably wondered: is renovation really worth it, or is there a smarter way forward?
For one family in the Cumberland LGA (Granville area), the answer was clear — knock it down and start fresh. The result? A 276.86m², double-storey contemporary home that won the Master Builders Association (MBA) NSW 2025 Award in the Project Home category.
Here's what went into making it happen.
Why They Chose a Knockdown Rebuild Over Renovation
The original home was outdated, poorly laid out, and energy inefficient. Renovating would have meant working around existing structural limitations — compromises at every turn.
A knockdown rebuild, on the other hand, meant starting with a clean slate. Same location they loved, brand-new home built specifically for their block and lifestyle.
The Design: Soho on a 12m Narrow Lot
The builder used the Soho design — a home specifically created for narrow lots — as the base, then customised it for the 12-metre-wide block.
Key features included:
Urban Farmhouse façade with a double-height pavilion entry
Open-plan living flowing out to alfresco and pool
Ground-floor guest suite for added flexibility
Raked ceiling with highlight windows for natural light
Double-glazed windows and upgraded insulation for energy efficiency
Passive solar design principles throughout
The entire home was delivered within a 9-metre build envelope — a tight constraint that required precise planning.
What Made This Build Challenging (and How It Was Solved)
Narrow lot builds in established suburbs rarely go without complications. On this project, a sewer encasement was restricting the footprint. Working with engineers, the team extended the usable area by 5 metres — at no extra cost to the homeowner.
Building in an established neighbourhood also meant managing demolition logistics carefully: strict site safety protocols, scheduled access, and minimal disruption to surrounding residents.
Digital project management tools were used throughout to keep the build on track and quality consistent.
The Outcome
An outdated, inefficient home became a modern, award-winning residence — maximising every centimetre of a narrow Sydney block.
This project proves that a knockdown rebuild on a narrow lot isn't just possible — with the right builder and the right design, it can produce a home that exceeds expectations in both liveability and architecture.
