FAQs
Common questions from homeowners
Do I need planning permission for a loft conversion?
Some loft conversions may be permitted development if they meet the required limits and conditions. A Lawful Development Certificate can help confirm this.
Can you submit the application for me?
Yes, submission support can be provided if required.
Do you do structural calculations?
Yes. Tekneca Studio prepares structural calculations for the agreed beams, openings, loft or extension. They are quoted separately from the planning drawing pack.
Are building regulations drawings included?
They can be prepared by Tekneca Studio, but they are a separate stage from the planning drawings and are quoted for the agreed scope.
Can you guarantee planning approval?
No. We can prepare clear drawings and support the application process, but the final decision is made by the local authority.
What information do you need to quote?
The property address, project type, photos, any existing drawings and a short description of what you want to build.
