FAQ
DO I NEED PLANNING PERMISSION FOR MY EXTENSION?
Most single storey extensons fall within the permitted development rules and do not require a planning application providing certain limits and conditions are met. Two storey extensions are more likely to require planning permission as there are additional limits and conditions to be met.
HOW LONG DOES IT TAKE TO GET DESIGN PLANS DRAWN UP?
In most cases we can do a measured survey within 7-10 working days and create the design plans within a further 7-10 working days.
DO YOU DEAL WITH PLANNING APPLICATIONS?
Submitting the planning application is one of the services we offer our clients.
DO YOU DO PLANS & DRAWINGS FOR BUILDING CONTROL?
Yes, we're more than happy to create building plans suitable for building control. We also provide a full plans application service.
HOW MUCH DO PLANS & DRAWINGS COST?
Prices vary depending on the style of property, the number of floors, the size of the extension and the changes to the existing layout. Our prices start at £795 plus vat for single storey extension plans.
DO I NEED PLANS FOR A PERMITTED DEVELOPMENT EXTENSION?
