Loft conversions

Make the most of your roof space

At Blink Architecture we undertake a large number of loft conversions in a variety of homes of different sizes and ages. We aim to make the most efficient use of the space available, saving you the cost of moving to a larger property.

As part of our consultation service we are happy to come and take a look at your property free of charge to see if the loft space can be converted. As well as offering any additional advice on design ideas and how to make the best use of loft space.

Planning your loft conversion

Most loft spaces can be converted to provide habitable space, including more modern properties which use trussed roof rafters. As part of our service we investigate different options for the layout of a loft conversion including placement of the stairs. We can then look to add dormer windows or change the roof layout to gain additional space (for example, changing a hipped roof to a gable end).

Most loft conversions require a structural engineer to assist with the design of the supporting structure. We work with local structural engineers and can arrange for a quote for this service on your behalf.

Checking the feasibility of your loft conversion

As a guide, these are some important things to consider when determining if a loft conversion is possible:

  • A loft conversion will require at least 2m clear headroom from the pitch of the new staircase and at the top of the staircase to the converted space
  • The floor joists to a loft conversion are usually 200mm deep and run alongside the existing ceiling joists so as not to disturb your existing ceilings
  • Depending on the size of the existing roof rafters you will need to allow an additional 100mm to the inside of the rafters for insulation

Do I need planning permission?

A loft conversion in your house is considered to be a permitted development, and doesn’t require an application for planning permission. This is subject to the following limits and conditions:

  • A volume allowance of 40 cubic metres additional roof space for terraced houses
  • A volume allowance of 50 cubic metres additional roof space for detached and semi-detached houses
  • No extension beyond the plane of the existing roof slope of the principal elevation that fronts the highway
  • No extension to be higher than the highest part of the roof
  • Materials to be similar in appearance to the existing house
  • No verandas, balconies or raised platforms
  • Side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor
  • Roof extensions not to be permitted development in designated areas**
  • Roof extensions, apart from hip to gable ones, to be set back, as far as practicable, at least 20cm from the original eaves
  • The roof enlargement cannot overhang the outer face of the wall of the original house
