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?
Structural calculations are separate from the planning drawing pack and are normally prepared by a structural engineer. If they are required, Tekneca Studio partners with structural engineers who can provide a quote to prepare them.
Are building regulations drawings included?
Not as standard. Planning drawings and building control drawings are different stages. Building regulation drawings can be discussed separately.
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.
