Attic Conversions

Attic Conversions

If you'd like some additional space, attic conversions are a great option. The beauty of attic conversions is that you are converting "dead space" without any impact on your garden or the rest of your house and at a lower cost than an extension.

First of all, is planning permission required for attic conversions?
In any cases, no. Your buiilder or architect will be able to advise you on that. You do require planning permission however if you intend to make alterations to the structure of your exiting roof, for example installing a dormer window, roof windows to the front and or side. Another point to note is that if you are making structural alterations you should get a "certificate of compliance". This certifies that the work has been carried out in accordance with the new building regulations and will be needed if you want to sell your house in the future.

What size will my room be?
Generally speaking your finished attic room will have an area of approximately 35-45% of your existing floor plan at ground level.

How long does it take?
On average, it takes approximately two weeks from start to finish to complete a straight-forward attic conversion, depending on the scope required. This time scale is increased as dormer windows & en-suites are included in the main scope of the works. Obviously the larger the job / scope the longer it takes to complete the works.

Are Steel beams used in attic conversions?
Yes, Steel beams known as RSJs are used. RSJ is an abbreviation of rolled steel joist and is also known as an I beam, steel beam or girder.

Important note: The correct gage RSJ must be used to comply with building regulations, this is dictated by the span and load it is required to travel and carry for your conversion.

What is a suspended floor?
A suspended floor, also known as an independent floor are anchored to the RSJ's (see note above) . This type of floor system is totally independent of the ceiling located directly below it, therefore there is no weight transfer from your new attic floor to the existing ceiling or ceiling joists below.

Can I get a similar staircase to my existing one?
The original stairs are normally located directly below the new one. It is nearly always possible to decorate your new stairs to match that of your original stairs in terms of base rail / hand rail / posts & spindles. In the unlikely event a match can not be achieved, some customers change their old banister rails to match that of the new ones.

Can modern truss rafter attics / lofts be converted?
Yes, although more work is required compared to that of a traditional cut roof.

My house is a timber framed house can it be converted?
