Probably the most economical way of adding value and extending your property to provide bedrooms, studies and additional bathrooms.
In most cases if your house was built prior to the 1970's and the vertical distance between existing ceiling joists and underside of the highest point of the roof is 2300mm (7ft 6in) or more then the loft space should be considered.
Loft conversions will always require Building Regulations consent and sometimes Town Planning consent. Due to their nature, loft conversions always require significant structural details calculations.
The photos show various loft extensions some taken to the maximum size with a conversion of the original sloping "hip" end to a vertical "gable" plus the addition of a rear dormer. Not all Town Planning Departments like this style, however they usually can be designed to fall within the permitted development limits.
Traditional masonry extensions to match the existing house often providing, additional accommodation and integral garages or lifestyle stores and if two storey bedrooms and ensuites over.
Side extensions, will always require Building Regulations consent and normally Town Planning consent
The photos show a typical extension, which has been built to meet the Local Authority Town Planning requirements to leave a one metre space to the boundary.
Normally single storey, extensions are used for larger kitchens and dining areas, either with pitched tiled or flat roofs. When combined with roof lights and internal alterations to open up existing living space, they can provide the light modern open plan kitchen dining living areas, so often seen in the design magazines.
The photos show large single storey rear extensions built to maximise open plan living space, one of them utilising different roof types either side of a parapet wall.
