What to check before you buy?

✓ Ensure Permitted Development Rights
In some rare cases, Permitted Development rights can be removed or altered. Check your council's website to see if your property is listed in Article 4 Directions, located in a Green Belt, or in a Conservation Area.

✓ Ensure Sufficient Space
The extension and any existing outbuildings must not exceed 50% of the land around the original house. Ensure this condition is met before purchasing our packages. The extension's width must not exceed the house's width, and the depth can be up to 3m.

✓ Check for Listed Building Status
If your home is a Listed Building, you must apply for Listed Building Consent. Contact us if you wish to work on a listed property. Ensure all modifications adhere to local heritage guidelines and seek expert advice if needed.

✓ Read Licence Agreement
Understand the terms and conditions of use for our architectural drawing packages. This agreement outlines your rights, limitations, and responsibilities to ensure proper and legal usage.
