What if I'm not sure whether I'll extend my house? Should I apply for planning permission?

You are entirely responsible for this decision. The value of your property can be significantly increased if your planning permission application is approved. Hence, it might be worthwhile if you plan to sell your house in the near future.

Should I inform my neighbour about my house extension plans?

We recommend that you talk to your neighbour first when you are planning to build a semi-detached or terraced house extension.

When the building work is being done, can I stay at home?

Indeed, if the scope of the work allows it and you can accommodate some disruption, dust issues, and noise, then you can do so. The contractors we work with will try to minimise these issues whenever possible.

Is it possible to plan, design, and build a basement extension?

Without a doubt. There is, however, a greater likelihood that this type of property extension will require planning permission due to the more complex structural changes involved.

How does Permitted Development work?

Homeowners are granted permitted development rights that give them more freedom to enlarge their homes. As long as you comply with relevant rules, it is possible to expand your property to a certain degree, more than the norm, without having to apply for Full Planning Permission, which can be a tedious and expensive process.

Several extensions include single and double-story extensions, loft conversions, front and rear porches, outbuildings, solar panels, dormer skylights, and new windows. In conservation areas, permits cannot be granted for double-story extensions, loft conversions larger than the original, flats or most properties.

Is building approval required for my project?

Building Regulations, drawings and controls are significant to ensure people’s safety in buildings. Approved buildings comply with national standards to protect people’s health and safety. Structural calculations, fire safety, insulation, dampproofing, foundations, heating, ventilation, and access are among the factors in building regulations. Before beginning construction, you must submit and approve building regulation drawings once you have received planning permission.
