Good to know

Common questions

General guidance about builders in the UK, not specific to any one business.

Do I need planning permission for an extension in Leeds?

Single storey extensions under certain size limits may fall within permitted development rights and not require planning permission. Two storey extensions usually need permission. Building regulation approval is always required. The local council planning team provides clarification on specific proposals.

How long does a loft conversion take?

A straightforward loft conversion typically takes 8–12 weeks from start to finish. Dormer conversions take longer. Complex structural work, asbestos surveys, or building control inspections can add weeks. Weather and supply delays occasionally extend timescales further.

What is building regulation approval?

Building control is a legal requirement ensuring work meets safety standards for structure, electrics, plumbing, heating and insulation. Inspections happen at key stages. Completion certification is issued on finishing. Most building work needs it, not just planning permission.

What causes pointing to fail on brickwork?

Old mortar cracks and erodes from weather, frost, water penetration and movement. Modern mortars sometimes fail on older lime-based bricks. Repointing with compatible mortar restores weatherproofing. Failure to repoint eventually allows water into the masonry and weakens walls.

Can a loft conversion be added to any property?

Most properties can be converted if headroom is adequate and the roof structure is sound. Structural surveys identify limitations. Flat roofs, low-pitched roofs, trusses and limited height all affect feasibility. Dormer or Velux windows can sometimes gain extra headroom where needed.

What should be checked before starting groundworks?

Underground utility locations must be identified to avoid water, gas, electricity and telecoms cables. Drainage and soil surveys confirm site conditions. Trees with preservation orders are protected. Building regulation and planning conditions affect foundation depths and methods.
