Certificate of Lawful Development

Most of your loft conversion and extension projects don't need planning applications. There's a cubic volume allotted to you by your Local Council. With a 'Certificate of Lawful Development', you can build to your permitted cubic volume. A Certificate of Lawful Development costs £86.00 plus drawing costs.

Making a major change to your building?

You'll probably need a planning permission when it's a large project. If a planning permission is required, you can approach us to help you get it. With an additional fee of £86.00 and extra drawing costs, you can begin your planning application and get a Full Planning Permission granted.

Building Regulations and structural calculations

Without Building Regulations Approval, you won’t have the certificates of compliance you may need when you want to sell your home. Choose Lusted Design to incorporate all the building and safety regulations in your project design. With our meticulous planning you'll save time and money.


The Building Inspector will view and log the various stages of the construction project and issue a Completion Certificate at the final visit.


Get a clear and cost-effective design by having us prepare structural calculations for your plan. These are used in conjunction with Building Regulations and can include such things as the calculation and sizing of steel beams and concrete footings.
