Loft Conversion FAQ
Our loft conversion drawing packages start from £595, with clear, fixed-fee pricing. The final cost depends on the type and complexity of your loft conversion and the services required. Request a free quote and we'll confirm the cost before work begins.
Loft conversions typically require existing and proposed floor plans, elevations, roof plans and section drawings. The exact requirements depend on whether your project requires planning permission, Permitted Development confirmation or Building Regulations approval.
Not always. Many loft conversions can be carried out under Permitted Development rights, subject to the property and proposed works meeting the relevant criteria. Other projects, including certain dormers and alterations in sensitive locations, may require planning permission. We can assess the appropriate route for your project.
Most loft conversions require Building Regulations approval. These requirements are separate from planning and cover matters including structural safety, fire protection, insulation, stairs and other construction standards. We can prepare the detailed drawings required for your Building Regulations application.
Yes. We can prepare and submit the relevant planning or Lawful Development Certificate application and act as your agent, dealing with the local authority throughout the application process where included within your package.
We can typically prepare your initial planning drawings within 72 hours once we have all the information required to begin. More complex loft conversions may require additional time, and we'll confirm the expected timescale at the outset.
