Type of work
Interior-only renovations need no planning approval. A&A and rebuilds need an architect, a structural engineer and approvals, which add professional fees and time.
Size and storeys
Landed homes have more floor area, more bathrooms and often a staircase and roof terrace to finish.
Condition of the structure
Older houses may need roof repairs, waterproofing, rewiring and new plumbing.
Finishes
Natural stone, timber and bespoke joinery are common in landed homes and raise the budget.
Approvals for landed renovations
- Interior renovations without structural changes generally do not need planning approval.
- A&A and reconstruction need plans prepared and submitted by a qualified person, typically an architect, with structural design by a professional engineer.
- Approvals add several months before construction starts, so plan your timeline around them.
Ways to save
- Decide early whether you need structural changes; staying with an interior renovation saves fees and months of approvals.
- Reuse sound structure, roof and windows where possible.
- Focus premium finishes on the living, dining and master bedroom areas.
Timeline: Interior renovations usually take 4 to 6 months, A&A works 8 to 12 months, and reconstruction 12 to 18 months, plus time for approvals. See our renovation timeline guide.
