Permitted Development Rights

What are permitted development rights? These are your rights to alter or extend your house without applying for planning permission. More information is available at
www.planningportal.gov.uk/uploads/100806_PDforhouseholders_TechnicalGuidance.pdf

Generally, permitted development is not allowed in conservation areas, on listed buildings or on other designated areas such as national parks, Areas of Outstanding Natural Beauty etc.

We are familiar with the rules of permitted development and can advise you on whether planning permission is needed on your project.  We will also apply for a “Lawful Development Certificate” from the local authority on your behalf.  This provides peace of mind by confirming that your proposed development is lawful and is helpful when selling your house.

Please contact us for a discussion on the full rules and how they may benefit your project.
