Planning
Extension or knockdown rebuild: how to decide
Marty Leonard · 16 June 2026 · 5 min read
Almost every client who calls us about more space asks the same question in the first ten minutes: do we extend, or do we start again? The answer usually comes down to the bones of the existing house and what the block allows.
Five checks worth making early
- Structure: are the existing footings, frame and roof worth carrying forward?
- Layout: does the current floor plan work with an addition, or fight it?
- Site: slope, access, easements and setbacks all shape what is possible
- Services: age and capacity of plumbing, drainage and electrical
- Value: what the finished home is worth against total project spend
Working through those five points with a builder and designer together, before drawings are locked in, is what keeps a project realistic. It is exactly what our consult and design stages are built to do.
