Garden rooms come in two main categories, traditional or contemporary design, which you choose is entirely dependent on taste.
Traditional style garden rooms have pitched gable, or hipped roofs and details like verandas with balustrade. Traditional garden rooms often have wooden casement windows and French doors.
Contemporary garden rooms on the other hand have much crisper lines and single pitch or flat roofs. Contemporary garden rooms have large expanses of glass and often walls of folding doors, which fold back to create a flowing indoor outdoor space. Doors and windows are often made of aluminium or UPVC which continues the modern feel.
Whilst traditional garden rooms have roof coverings like cedar shingles or clay tiles contemporary garden rooms have modern roof coverings like EPDM rubber and sedum roofs.
When it comes to external cladding a contemporary garden room is often finished with cedar tongue and groove cladding which starts off a reddish brown but with time weathers to a silver grey colour. Traditional garden rooms on the other hand are often finished with shiplap or tapered weatherboard and are often painted.
When you go inside the garden room, contemporary rooms are normally finished with plasterboard and a skim of plaster this gives a crisp finish and the feel of a room in the house. Traditional designs can also have plastered interiors although some companies line their rooms with wood panelling either in the form of vertical tongue and groove boards which once painted gives a soft shaker style finish or plywood lining which can also be painted.
Whether your taste is the traditional or contemporary design a garden room is a versatile addition to your home.
