Preformed Fibrous Plaster Arches
Stevensons offer a range of arches, architraves and staff beads to suit any width of arch opening and with numerous arch design options as well as complete bespoke arches designed by our in house designers.
Semi-Circular and Eliptical Arches
Stevensons arch design details have been produced exclusively for us by the distinguished classical architect Ben Pentreath with the guidelines established by James Gibbs (1682-1754) in mind.
Arches, architraves and staff beads can be set out as half round, oval 60° and oval 30°. The curved section of the arch, architraves or staff beads can run continuously down to the skirting or rest on a simple or detailed impost moulding. At the top of the radius a simple or a detailed keystone can be introduced.
How Much Does A Preformed Fibrous Plaster Arch Typically Cost?
The prices shown can include architrave, staff beading and keystone if required. The preformed plaster arch will include the soffit and any wall infill needed as a unit to be inserted complete in any opening to be converted into an archway.
These prices apply to semi circular and semi eliptical arches. Other arch profiles, for example the gothic style, can be quoted case by case as bespoke.
