Plan your loft-to-living-space project with this step-by-step conversion checklist.

• Measure loft space and record usable dimensions

  Include floor area, ridge/head height, and hatch access clearances.

• Identify roof and loft structure type

  Note trussed rafters vs cut roofs, hip/mansard shapes, and span lengths.

• Order a structural survey from a qualified engineer

  Request load assessment, joist condition, and roof/party-wall checks.

• Confirm floor and joist strengthening requirements

  Get engineer's specification for new loadings and any reinforcement.

• Check planning permission vs permitted development rules

  Contact your local planning authority or check online guidance.

• Prepare and submit a planning application if required

  Include drawings, elevations, and neighbour/heritage considerations.

• Review building regulations requirements

  Confirm requirements for insulation, fire safety, stairs, and structural works.

• Submit building control application or appoint an inspector

  Arrange approvals before starting major structural or services work.

• Design a compliant staircase and ensure adequate headroom

  Plan pitch, width, landing, and head clearance to meet regs.

• Plan fire safety measures and means of escape

  Specify escape routes, fire doors, alarms, and fire-resistant materials.

• Choose window type and placement (rooflight, dormer, or gable)

  Balance daylight, ventilation, privacy, thermal performance, and planning impact.

• Develop insulation and ventilation strategy

  Specify warm/cold roof, U-values, vapour control, and mechanical or passive ventilation.

• Plan electrics, lighting, and heating layout with a qualified pro

  Map wiring runs, lighting zones, heating outlets, and extract fans for bathrooms.

• Include plumbing and drainage planning if adding a bathroom

  Check waste pipe fall, SVP access, and location of water supply and hot-water system.

• Obtain detailed written quotes from at least three contractors

  Compare scope, materials, timelines, warranties, and references.

• Prepare a budget, timeline, contingency, and appoint a project lead

  Include 10–20% contingency, milestones, payment schedule, and a single point of contact.
