Consider the size of the dormer in relation to the size of the roof slope. A large dormer can lead to structural complications in the design of trimming members to the existing roof, and in certain cases the introduction of steelwork. A more conservative approach can prove to be the most economic. www.marchitectsltd.com

Consider what kind of window you wish to install to the Dormer. As a minimum they should be fully reversible for safe cleaning from the inside. No fixed panes. The cill height will be dictated by safety too and if applicable whether the window is an escape type or not. www.marchitectsltd.com

Designing a flat roof to a dormer may be unavoidable because of the proximity of the existing ridge. Although three layer felt is the most economic option it will need to be maintained over its 10 year lifespan. Consider alternatibes like single ply or sheet metal. www.marchitectsltd.com

As well as considering the floor construction in terms of fire, the new attic floor is now considered to be an intermediate floor under the building standards and requires to achieve a specific noise reduction rating. There are approved constructions however it is difficult to reflect those when you are dealing with an existing situation. Depending on the council building controls view you may have to reline the ceiling below to achieve the density of plasterboard.  www.marchitectsltd.com

Once the position of the stair has been determined, consider introducing natural light if possible from the roof. This will give an attic sized stair the impression of space even though it is likely to be contained within a confined area. A roof window or even a light tunnel can have a dramatic effect. www.marchitectsltd.com

The creation of a protected enclosure can be frustrating for the home owner as it will affect parts of the house otherwise unaffected by the works. It will involve the installation of fire doors and may involve upgrading of partitions forming the protected enclosure where these do not meet the minimum fire resistance requirements (normally 30minutes). Depending on the route the stair takes it may also require localised upgrading of ceilings to rooms below. www.marchitectsltd.com

What height will your new floor be above ground? As a rule of thumb, if you are creating one above an existing first floor the stair will have be enclosed by a protected enclosure which needs to be created all the way to the front door. This provides a means of escape for the occupants of the new room. Sent using BlackBerry® from Orange
