• If you engage an architectural technician you will pretty much always end up with a better end product.
  • Architectural technicians are highly trained and are especially good as seeing the “big picture” – in making the best of the space you have, in getting interesting designs, in ensuring the light is right, the feel is good, and that the house works.
  • Architectural technicians are usually good at ensuring the work is professionally done – that it meets the requirements of building control, that you have a structural engineer if you need one. A specialist is good at the detail that most of us rarely think about and which, if done wrongly, can end up being costly mistakes – which way should the door open? Should we have recessed lights? Where should the outlet pipes go? Should you be able to see the toilet when the bathroom door is open?
  • An architectural technician can also help you find the best builder, project manage the whole works, and keep within budget. It’s our job to represent your interests with builders and local authorities. Pyramid Architectural Design are a team of architectural technicians based in Middlesbrough and provide architectural services in Middlesbrough, Redcar, Marske, Guisborough and surrounding areas.

How much will building an extension cost?

Depending where you are in the UK, for a straightforward extension you should allow around £1,000–£2,000/m2. But, the cost of your extension will all come down to a number of factors, including size, specification and location.

Building a single-storey extension will cost the following per/m2:

  • Basic quality: £1,000 to £1,680
  • Good quality: £1,680 to £1,920
  • Excellent quality: £1,920 to £2,160

Building a two-storey extension will not cost much more per square metre because, aside from the extra interior fixtures and finishes, you are only adding walls and floor joists — a roof and foundations are required whether your extension is single or two storey.

Building Regulations for Building an Extension

Whether you require planning consent or not, you will need to make sure you comply with Building Regulations. To meet the Regs, you can either submit a Full Plan Submission or a Building Notice.

  • Full Plan Submission: send plans to your local authority building control or approved inspector prior to the build for approval. The building inspector visits your site at different stages and inspects the work as it progresses
  • Building Notice: a statement which lets the local authority know that you will be complying with the regulations in building your extension and gives the building control department 48-hours notice of your intention to start the work. Building inspectors will inspect the work at various stages and will advise you of any problems

A Building Notice is the riskier of the two as you may only find out you have a compliance issue once building work has started, which then needs to be paid to be put right.
