Structure behind the shopfront
A shop window or entrance sits under the front wall of the building, and often under one or more floors of flats or offices above. Widening it, lowering the sill, or moving the door removes masonry that carries those loads. The new opening needs proper support, usually in the form of a steel beam or lintel and, at the sides, solid piers or posts.
Common alterations
- Enlarging a window for better display and light
- Forming a new or wider entrance
- Replacing an old fascia beam or rotten shopfront timber
- Installing steel supports for bi-fold or large glazing
- Reinstating a traditional shopfront with stone or timber detail
- Creating level access, see level-access entrance construction
How the work is done
Design comes first. A structural engineer calculates the beam and pier requirements, and building control normally checks the work. During construction the upper floors are temporarily supported using props and needles while the old masonry is cut out and new steel is installed. Padstones, bearings and fire protection to the steel are important details. The new frontage is then finished and glazed, and any pavement or door thresholds made good.
Local streets and buildings
Newcastle city centre, Tynemouth, Gosforth and the local high streets include many Victorian and Edwardian shopfronts with flats above. Their upper walls often rest on small timber or cast iron members that have corroded or rotted over time. When opening up a frontage we may find hidden defects that need repair, and in conservation areas the character of the shopfront may be protected.
Permissions to think about
Alterations to a shopfront often require planning permission, and listed building consent if the building is listed. Advertising consent may also be required for signs. Building Regulations will apply to the structure. If the wall is shared, the Party Wall etc. Act 1996 may be relevant. Start with the Planning Portal and see GOV.UK.

Frequently asked questions
Can my shop stay open during structural work?
It depends on the scale of the work. Some jobs need the front area closed for a period, while others can be phased. We discuss access and safety with you in advance.
Do I need planning permission for a new shopfront?
Often yes, especially in conservation areas or on listed buildings. Contact your local planning authority or check the Planning Portal before starting.
