DP Loft Conversions offer a free quotation to customers interested in converting their loft or attic. This takes much of the initial project risk and cost from customers and allows them to concentrate on other aspects of the build such as the design of the new loft space, the quality of build on offer and the final cost for that. Below are two sample projects and the rule-of-thumb on allowances under permitted development schemes.

Example Project: Terraced or End-of-terrace Houses
Generally 50 cubic meters is allowed under permitted development.

Example Project: Semi-detached or Detached Houses
Generally 70 cubic meters is allowed under permitted development.

Gaining Permission to Build

What the figures above mean is, in most cases, so long as the project doesn’t contravene local planning regulations and requirements, you will most likely be able to convert your loft under permitted development provided you have building regulations approval. The advantage to your loft conversion project is that the cost will be far less, there is much more flexibility what may be designed for the final layout of the loftspace and permission to build can be obtained much ,more quickly. We are able to advise on this. If you are within the limits laid down by the council, the size of your property, local unitary development plans, whether you live in a conservation area, etc. we will assist you in submitting your drawings to secure building regulations permission. This tends to be much quicker and more straightforward than having to get planning permission.

Exceptional Circumstances

As noted above, there may be certain circumstances in which gaining approval may not be as straightforward, e.g. you may have already extended your house: in cases such as this you will probably need a Certificate of Lawful Development. To secure this the council will require a visit to take measurements of the extension(s). So long as these, combined with your proposed loft, fit within permitted development there should not be a problem. Again, we are usually able to advise at all points on this.

Tip: One reason to pursue permitted development (building reg’s approval) is that sometimes when the drawings are submitted for planning permission planners will ask for a reduction in the volume of the dormer. In these cases the loft may end up rather smaller than it would have under permitted development.

When you may need Planning Permission

If your existing extensions and proposed loft exceed the permitted development allowance for your house the drawings may have to be submitted for planning permission approval. This may take up to 8 weeks before you have an answer either granting or refusing you permission.
