Quality House Extensions and Structural Work
As professional building contractors since 2005 we trade on our reputation, but this reputation isn’t just for good value or exemplary workmanship. Our clients come back to us again and again because we offer them something more: peace of mind. When it comes to large jobs such as house extensions, we know this is more important than ever.
That’s why our team works hard to put your mind at ease and answers all your questions (as well as the ones you may not even think to ask) before we pick up our tools.

Will I require planning permission?
A great benefit of house extensions is that they are often considered to be a permitted development, which means planning permission may not be required. However, this is subject to a number of conditions such as, a single-storey side extension not being higher than 4 metres or the eaves of the extension not exceeding the height of the eaves in the existing property. We can offer guidance and assistance with planning permissions.
Which building regulations are going to apply?
Regardless of whether your project requires planning permission or not, most house extensions in Beckenham and throughout the UK need approval under the Building Regulations 2010. This is especially true when planning to replace or install windows, doors, electrics, heating systems, plumbing and roofs. We’ll help you to establish the exact approvals needed from your local authority.

How long does the planning process take?
This will depend on the type of extension being planned, for example planning single-storey side house extensions will likely be quicker than the time required to outline a two-storey wrap-around house extension. Whatever your vision, our team strive to make the planning process quick and efficient for all our customers, whilst ensuring all your requirements are met.
Do I need approval to build a porch or conservatory?
Porches are classed as a permitted development so do not require planning permission, as long as the porch area does not exceed three square metres. Conservatories are also seen as a permitted development but will often require building regulations approval. Our experts can provide more detailed advice on this during the consultation.
