Converting a Loft as Permitted Development

The Affect of Covid 19

Our research shows that Google searches for ‘converting loft’ increased by over 250% during the first Coronavirus lockdown in the UK. We have analysed Google keyword search statistics which indicate that, since coronavirus restrictions earlier this year, UK households are looking to create more living space in their homes by converting their lofts and adding extensions. We wanted to respond to this surge in interest by providing some helpful advice on loft conversion plans and Permitted Development drawings cost as most loft conversions are built as Permitted Developments.

Do I Need Drawings For my Loft Conversion?

Whilst most loft conversions don’t need planning permission, you will still need an accurate set of drawings to submit to the Council so you can prove that your loft conversion has been done legally. This process is called a Lawful Development application and, unlike Planning Permission, doesn’t require your neighbours to be consulted and their objections invited. The drawings that you will submit to the Council are not the same as construction or structural drawings that your builder will use, as the Council requires planning drawings. These loft conversion plans will show the loft conversion relative to the original building and drawn to 1:100 scale on A3 showing elevations and floor plans with a north point.

Permitted Development Drawings Cost

An architectural designer will be able to produce the drawings you need for your Lawful Development application, however, they will first have to consult with you, as your designer, to establish the optimum layout design that you want to build. This involves producing aa accurate virtual reality 3D model of your house that the new loft space can be added to. We have found that, loft conversions are the hardest space for a homeowner to visualise becoming a pristine new bedroom, bathroom, office, prayer room etc as lofts are usually dark, dusty places and have exposed roof joists with bits of roofing felt hanging down etc. Furthermore, dormer loft conversions involve cutting the rear roof slope and extending the rear wall of the house upwards into the loft and adding a flat roof from the roof ridge to the new extended rear wall. Dormer loft conversions are very effective at adding a lot more usable space to your loft. Whilst these are very common types of loft conversion, this degree of modification can make visualisation particularly difficult and therefore challenging to plan adding your furniture to. If you are planning a loft conversion, I highly recommend hiring an architectural designer who uses a VR CAD system to design the space, as it will help you make better decisions (e.g. door and partition positions, selection and position of bathroom suite, whether your furniture will fit and where it will go etc) during the design phase instead of during the build phase which would extra cost, be very stressful, cause delays and compromised end results. My Planning Drawings charges £495 to design a loft conversion and produce a set of loft conversion plans for your Lawful Development application. We can also submit and manage the application for you and for this we charge £245.
