A Building Permit is required for basement construction or alteration, unless the changes are strictly cosmetic. With all building work, the owner of the property (or land) in question is ultimately responsible for complying with the relevant planning rules and building regulations (regardless of the need to apply for planning permission and/or building regulations approval or not). Therefore, failure to comply with the relevant rules will result in the owner being liable for any remedial action (which could go as far as demolition and/or restoration). The general advice is to always discuss your proposals with the relevant Local Planning Authority and Building Control Service before starting work on any basement construction or cellar conversion.
You can apply for planning permission online through the Planning Portal or we can apply in behalf of you by completing the relevant forms, attaching supporting documents and plans and paying the application fee.Following the approval of your planning application, if your basement construction involves significant structural works, a structural design and calculation may have to be done by an engineer.When your design is complete, we sit down with you to firm up the detail of the project and make any adjustments so you can be confident with your design and make changes before it's too late. We will than accurately price the approves design which will hopefully form the basis of the contract documents and the works on site.
