Upward Extensions Permitted Development - August 2020

A new permitted development right has been introduced since the 1st August 2020 that allows up to two additional storeys on an existing flatted residential building. To qualify, the building must have been constructed between 1st July 1948 - 5th March 2018. To qualify buildings must be:

  • Free Standing and purpose built as flats.
  • Three storeys or above
  • Including any extensions, no taller than 30 metres.
  • Floor to ceiling heights must not exceed those of the existing building or 3 metres in height.


  • Heritage buildings, Grade listed buildings or land within its curtilage.
  • Statues / monuments. Scheduled monuments or land within its curtilage
  • Natural reserves & sites of special scientific interest.
  • Dangerous sites & areas with safety hazards
  • Land within 3 kilometres of the perimeter of an airfield.
What is needed to submit an application?

The legislation sets out the requirements in terms of what needs to be submitted to the Local Authority. Architect7 can help building owners understand the planning policies around upward extensions and can submit Permitted Development applications.

How much do architects charge?

On average, a traditional practice will charge between 5% - 10% of the project cost.

This is the full amount that you will expect to pay. Throughout the whole build. Even the communication and support is included in the architects fees for any project from drawings to build completion.

For instance, if you are planning on building a 5 meter rear extension & kitchen renovation in London and your project costs £80,000 overall, you may find that with a traditional practice, expect to budget between £4000 and £8000 for your architect.

However before you commit to any build work measured drawings & planning permission applications will only cost you around the £1450 mark. Now, if this is your first time remodelling a home, it can be difficult to work out these costs upfront. After all, what’s 10% of a budget you haven’t decided on yet?.

Building Regulations / Building Control

The local authority is obliged to make sure that the standard of building work in their borough complies with Building Regulations. Architect 7 have built up communication history with the Building Control Department in the Flintshire authority such that we already have a precursor to what plans are likely to pass eve before the application is submitted.
Building Control applications are submitted to the council together with a fee. The amount is usually based upon the scale of the build.

Basement Planning Architects in Flintshire

Planning authorities have tightened their restrictions on basements and require additional information with any basement application. However many people are surprised to learn that planning permission for basements can still be easier than for some other types of project. This is because a basement will have no impact on the appearance of the house above ground, and a basement does not create overlooking or affect a neighbour’s amenity directly. In fact, if the basement is just under the house (not the front or rear garden) it can even be Permitted Development. To satisfy the planning department a well written Basement Impact Assessment will need to be submitted as part of the planning application.
