Every home and brief is different, but a realistic budget starts with the scope, condition of the property, structural work, specification and access.

What does a house renovation cost in North London in 2026?

For a whole-house renovation in North London, published market guides commonly show broad planning ranges of roughly £1,500–£2,500 per m² for a mid-to-high-quality renovation. Premium finishes, complex period-property work, major structural changes or extensive bespoke joinery can take the cost higher.

This is a planning guide, not a quotation. North Star Building Solutions Limited prices each project from agreed drawings, the specification, survey information and site conditions.

What should a renovation budget include?

Why costs vary so much in North London

Period homes can hide issues behind finishes. Access restrictions, parking, neighbours, party-wall matters, chimney work, damp, outdated services and structural openings all affect programme and cost. The quality of fittings and level of bespoke joinery can also change the budget considerably.

How North Star helps clients budget properly

North Star Building Solutions Limited manages renovations from initial discussion through to completion. Before starting work, we help clients clarify the scope, understand practical construction requirements and build a clearer route from survey and design to construction and handover.

The most accurate way to budget is to share the property location, photographs, approximate floor area, drawings if available, the rooms you want to change and your intended level of finish.

Frequently asked questions

Does the guide include an extension or loft conversion?

No. An extension or loft conversion should normally be budgeted separately because structure, foundations, roof work, glazing and approvals can materially change the cost.

Should I keep a contingency?

Yes. Older London homes can reveal concealed issues once work starts. The appropriate contingency depends on the age, condition and survey information for the property.

Can I get a fixed quotation?

North Star can prepare a project-specific quotation once the scope, drawings, specification and relevant site information are clear enough to price responsibly.
