07393 355531Do You Need Planning Permission for a Garden Office?
Whether you need planning permission depends on the size, height, and location of your proposed building on your property. In many cases, garden offices can be installed under permitted development rights if they meet specific criteria regarding proximity to boundaries and total floor area. However, if your building is intended for primary commercial use or is located in a conservation area, different rules may apply. We conduct a site assessment to clarify your specific planning requirements before we break ground, ensuring the entire process remains compliant with local West Sussex authority standards.
