London period house exterior with architectural character — garage conversions in London

What's covered

This page is the deep-dive index for Garage Conversions. Read it linearly or jump to the section you need.

1. Why people choose garage conversions

Three common drivers in London: family-growth space pressure, value uplift on Victorian/Edwardian stock, and rising rent making moving up the ladder uneconomic. Garage Conversions captures all three.

2. The planning route

For most London homes that aren't flats, listed or in conservation areas, garage conversions qualifies under Permitted Development. The garage conversion drawings test: under volume threshold, materials match, eaves setback. Where Article 4 applies, the LDC route gives certainty before building. Where conservation rules apply, full planning is required.

3. Building regulations

Part L (thermal), Part B (fire), Part M (access), Part K (stairs/falls), Part E (acoustic), Part F (ventilation). Each governs a different aspect of the garage conversion drawings. Sign-off via LABC or Approved Inspector.

4. Pricing in detail

Council fees: £103-£206. Building regs fees: £400-£900. Structural engineer: £800-£1,500. Build cost: separate quote from a contractor.

5. Common pitfalls

Wrong PD assumption (Article 4 area). Material non-match in conservation areas. Insufficient Heritage Statement detail on listed property. Missing Party Wall notice triggering legal injunction. We solve all of these as standard.
