Of all the types of property extension the conversion of a loft space is one of the more affordable in comparison to a side or rear extension and they do, of course, see you gain additional bedroom(s). So, what are the various types, are what do they typically cost?
Simple dormer extension
This is the most common and most affordable extension and is a good option for most property types. It creates additional headroom by creating a box shape out of the rear slope of the loft, with the outside walls often set back from the party parapet wall. The roof tends to be felt, whilst the walls are finished with hung tiles. You can typically avoid planning permission and go for permitted development instead.
L-shaped dormer extension
This is the same as the dormer extension above but includes an extension over the rear outrigger (the rear part of the L in a Victorian property) in which you can get either an additional bedroom, or a much larger bathroom compared to the smaller en-suite found in the simple dormer.
Hip to gable conversion
This type is found in end of terraced, semi-detached, detached properties, or bungalows and involves extending the inwardly sloping roof, creating a vertical wall. They are more expensive than mid-terraced dormer extensions by virtue of having to build up the side of the roof to then create a dormer. Semi-detached properties can end up looking lop-sided if only one neighbour has undertaken a conversion.
What are the next steps?
A good architect will show you how to maximise the space you have for your budget and advise you which options do and don’t require planning permission. They will produce planning/conceptual drawings and then drawings that are suitable for Building Regulation approval. You will also need an engineer who will determine where the steel beams are located, having undertaken loading calculations.
Unless you are in a detached house, you will need to consider the Party Wall Act, ideally 2-3 months before you plan to start works. Loft conversions in the grand scheme of things are relatively straight forward, but it is still worth giving your neighbours the heads up to maximise your chances of a favourable response.
