Loft Conversion

We are genuinely shocked how much space we had in the loft. The modern dormer idea you came up with has given us stunning views to enjoy from our bedroom. We’d have never done this without your ideas and help throughout the whole project.

Planning Permission

Planning permission isn’t needed for most loft conversions, unless you’re adding a dormer to the front of the house or you’re in a conservation area.

Impact On Your Home

Build Timescales

A loft conversion can vary from 2 to 3 weeks for a DIY/shell loft, through to 6 to 8 weeks for a full loft conversion with large dormer and ensuite.

Loft Conversion Design Ideas

Here is just a small set of ideas you might consider for your next loft conversion project.

Type Of Loft Conversions

A loft conversion can take many forms, but here is a quick summary of some of the most popular options for a modern loft conversion.

Velux Conversion Within Existing

Eaves style loft conversions are the type we all know where we have to duck slightly as we walk around the room. They make use of the existing space, and benefit from the addition of roof windows, often called Velux, drawing in significant amounts of light. They are seen as the most cost effective to complete, and involve little external structural work if any at all. This loft conversion rarely requires planning permission, but will require building regulations.


Dormer Loft Conversion

A front or rear dormer is a window featured addition to the rear of the roof. A dormer loft conversion will provide you with additional standing headspace, therefore adding to the larger feel of the room, as well provide better space for the staircase access in most cases. Dormers to the rear of a property are very popular due to their aesthetic appeal. They do not detract from the design of the front of the property and 99% of the time do not need planning permission.


Hip To Gable Conversion

The hip-to-gable loft conversion style extends the sloping side part of the roof (typically on an end of terrace or semi-detached property) out vertically, creating the gable, taking the wall all the way up to the ridge of the roof, adding significant height across the full width of the property. This required part of the roof being stripped and replaced, similar to a roof lift. The conversion usually falls under “permitted developments”, which doesn’t need planning permission.


L-Shaped Dormer Conversion

This type of loft conversion really does maximise the amount of space created for those home which have ‘L’ or ‘T’ shaped roofs. The biggest advantages often come when you want to create two separate bedrooms, and the main attic space only allows for a single room. You may also use the additional space to create a master bedroom with ensuite and walk-in wardrobe.


Modern Truss Loft Conversion

The modern trussed loft was introduced during the late 1960’s as a way of making it cheaper to build a roof. Unfortunately, this means diagonal bracing timbers are used to give its strength. This in turn makes it more difficult to make into a usable loft space.

We find many companies do not have the expertise do complete these types of lofts. Milestone Lofts have converted many of these into all types of loft including dormers.


Roof Lift Loft Extension

If your wanting a new loft conversion but the existing attic space doesn’t have the headroom to make it viable, then a roof-lift is the answer.  A roof-lift conversion is where the ridge line of your existing roof is raised by constructing a new roof to the right height and pitch, providing all the additional space needed to create a really good sized room or rooms.

As this type of loft conversion modifies the existing height of the roof line, then it will require planning permission.


Hobby Or Occasional Room

What some an occasional room, a home office and place to indulge your hobby, then the loft might well give you this space. With form or attic/loft conversion, you still complete all the core strengthening and insulation work needed to make it a safe and usable room space, but with out the extra costs of adding a permanent staircase and all the additional fire regulation changes needed for a loft conversion.


Part/DIY/Shell Conversion

Whilst this is not a ‘type’ of loft conversion as such, it is an important factor for some. With so much involved with converting a loft within building regulations and local planning laws, the cost can be too great for some. Milestone Homes & Loft Conversions, however offer a DIY or Partial loft build, where we complete only what you need and leave the rest to you. Our most popular is the for us to complete the structural shell work only including staircase and windows. This then leaves you weather tight you a big empty space to make whatever you choose.

Do I need planning permission for a loft conversion?

Planning permission is not normally required. However, permission is required where you extend or alter the roof space and it exceeds specified limits and conditions.
A loft conversion for your house is considered to be permitted development, not requiring an application for planning permission, 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.
*Bear in mind that any previous roof space additions must be included within the volume allowances listed above. Although you may not have created additional space a previous owner may have done so.
**Designated areas include national parks and the Broads, Areas of Outstanding Natural Beauty, conservation areas and World Heritage Sites.
Please note: The permitted development allowances described here apply to houses and not to:
  • Flats and maisonettes
  • Converted houses or houses created through the permitted development rights to change use
  • Other buildings
  • Areas where there may be a planning condition, Article 4 Direction or other restriction that limits permitted development rights.
