Exterior Loft Conversion Designs

From Roof Lights To Dormers

Even though most styles and sizes are now OK because of the new permitted development laws a tasteful exterior that blends with the surrounding environment will not only look good but it will easily increase the value of the property.

One style that won’t be permitted, and we should all be thankful for it, is the huge, squat and ugly dormers that were flung up during the1980s.

These blots on the landscape are truly awful and no way will a householder be allowed to build one today.

Permitted Development

In October 2008 new permitted development regulations were adopted by the government which allowed homeowners greater freedom in designing and building extensions including loft conversions.

Basically, the new regulations mean that a loft conversion is a permitted development and does not require planning permission as long as certain criteria are fulfilled.

This makes it very much easier for the homeowner when considering external loft conversion designs as most projects, even those involving the building of a new gable end, do not have to go through the planning process.

One caveat here though; remember that all loft conversions need to meet the building regulations.

The building regulations impose a standard of acceptable work on a project and are separate from the planning laws.

The Permitted Development Regulations

There is no need for the homeowner to apply for planning permission for his project if:

*50 cubic meters can be added to the roof space of a detached or semi-detached house falling to 40 cubic meters on terraced properties.

* Dormers will not be permitted to the elevation of any roof that fronts on to a highway.

* Any extension should be no higher than the ridge line of the existing property

* Dormers should be set back from the eaves by a minimum of 20 cm.

* Verandas, balconies or raised platforms will not be permitted.

Those projects that do contravene those guidelines will not necessarily be refused planning permission but a full planning application will need to be made by the homeowner.

Exterior Loft Conversion Designs

Unlike inside the roof space the options for external design is quite narrow. If the size of the available internal roof space is already substantial than skylights fitted flush to the existing roof slopes will be the best choice.

These kind of windows are very easy to install and are very cost effective; your design considerations will probably be limited to deciding how many skylights to have, their size and how to position them so that the new loft room benefits from the maximum amount of natural light.

If, however, the internal space is not very large than some sort of dormer on the reverse side of the roof will be the answer. Again, the only real considerations will be the size and how to blend the dormer into the existing building.

Once you have decided on the external loft conversion designs than the fun in actually designing the new loft rooms themselves can begin.
