Traditional shopfront reinstatement in a conservation area

Reinstating a traditional shopfront in a conservation area is one of the few planning applications where the authority is actively on your side, and it still gets refused when the drawings are wrong. The design has to be derived from evidence about what was there rather than from a catalogue of period details, the security has to sit behind the glass line, and the submission has to be drawn at a scale that shows the junctions. Get those three right and the application is usually straightforward.

Section 72 of the Planning (Listed Buildings and Conservation Areas) Act 1990 requires special attention to be paid to the desirability of preserving or enhancing the character or appearance of a conservation area. A good reinstatement is enhancement, which is the strongest position an applicant can be in.

Why authorities encourage reinstatement

Most conservation area appraisals identify the loss of original shopfronts as the single largest cause of harm to the character of a historic high street. The buildings above survive and the ground floor has been stripped: pilasters cut away, stallrisers removed and the glazing dropped to pavement level, deep fascias covering the first floor cill band, and external shutter boxes above.

That diagnosis is why so many authorities publish a shopfront design guide. The guides are usually clear, illustrated and practical, and an application that follows the local guide and says so is reading from the officer's own script.

Reinstatement also has commercial logic that is worth stating in the application. A well-proportioned traditional frontage distinguishes an independent business from a chain fit-out, and the authority's enhancement objective and your trading objective point the same way. Officers are more persuaded by that argument than by heritage sentiment.

Researching what was there

A reinstatement has to be evidenced, because an invented Victorian shopfront on a Georgian building is a different kind of harm. Five sources do most of the work.

• Historic photographs held by the local studies library, the county record office and the Historic England Archive, including street scenes where your building appears incidentally
• Fire insurance and commercial street plans, and successive editions of large-scale Ordnance Survey mapping, which show frontage lines and building footprints
• Trade directories and sale particulars, which date occupancies and sometimes describe the frontage
• Original architects' or builders' drawings, where the building is of a date and status likely to have generated them
• The building itself, which almost always retains more than it appears to

That last source is the most underused. Open up carefully and you may find pilaster bases behind boxing, corbel stubs at fascia level, the ghost of a stallriser in the brickwork, a mosaic or quarry tile threshold under a modern floor finish, surviving blind box housings, and paint layers that give the historic colour sequence. Photograph and record everything before anything is removed, and consider a formal record where the surviving fabric is significant, which the historic building recording page explains.

Neighbouring units in the same terrace are the other obvious evidence. Where the building next door retains its frontage, the proportions, the fascia depth and the pilaster width can be taken directly from it and the argument is close to unanswerable.

The parts of a traditional shopfront

Reinstatement is an exercise in proportion, and the elements work as a system. Getting one dimension wrong throws the rest out.

Two dimensions do most of the damage when they are wrong. A fascia that is too deep is the commonest fault, because modern signage wants height and the historic proportion does not allow it. And a stallriser that is too low makes the glazing look as though it is sliding into the pavement.

Take the dimensions from the evidence and from the local design guide rather than from the signmaker's preferred panel size. Where no evidence survives, a simple, well-proportioned contemporary frontage that respects the structural bay and the cill line is usually preferred to a conjectural reproduction, and most design guides say so.

Security without an external shutter box

External solid roller shutters are the single most common reason a shopfront application is refused in a conservation area. The shutter box above the fascia breaks the cornice line, the guide rails cut through the pilasters, and the closed shutter presents a blank metal face to the street at night, which is what conservation area policy is trying to avoid.

The design answer is to put the security behind the glass line.

1. Laminated glazing, which resists smash and grab without any visible security measure at all, and is often sufficient on its own.
2. Internal lattice or mesh grilles mounted behind the glazing, on an internal headbox concealed within the fit-out.
3. Demountable bar grilles fitted internally at night and stored during the day, which suit a small frontage.
4. Internal perforated or brick-bond shutters, where the authority accepts them, offering some visibility through the frontage.
5. Security film on individual panes, as a low-cost measure for a modest unit.

Where an external shutter is unavoidable because of an insurer's requirement, expect the authority to want a perforated or open-weave curtain, the box concealed within the fascia depth rather than above it, and the guide rails set within the reveal rather than across the pilasters. Provide the insurer's requirement in writing, because an assertion that the insurance demands a shutter carries little weight without it.

Level access within a traditional frontage

A traditional frontage and accessible entry are compatible, and the recessed doorway is what makes it possible.

The recess gives you depth to form a shallow internal ramp or a level landing without raising the external threshold, which protects the stallriser proportion and the historic threshold finish. Where the step is small, a level threshold within the recess with a discreet ramp behind the door line usually works. Where the step is larger, a platform lift inside the unit may be the answer.

Part M applies to the works and the Equality Act 2010 duty on service providers to make reasonable adjustments runs alongside. Neither requires the destruction of a historic threshold. Where a mosaic or encaustic tile threshold survives, keep it and design around it, and record it before any work starts. The same principle applies to historic surfaces in the street itself, as set out in the note on historic paving, setts and kerbs in conservation areas.

Signage and illumination

Advertisements are controlled separately under the Town and Country Planning (Control of Advertisements) (England) Regulations 2007. Some signs on business premises have deemed consent subject to limits on size, height, projection and illumination, and those limits are tighter in conservation areas and in areas of special control. Internally illuminated signs generally need express consent.

What design guides consistently prefer is signwritten lettering applied directly to the fascia, or individually applied letters, rather than an applied box panel. For illumination, the preferred approaches are external trough or spotlight lighting on discreet fittings, or individually halo-illuminated letters, rather than an internally illuminated plastic fascia.

Two further points. A projecting hanging sign on a traditional bracket is usually welcomed and needs its own consent, and the bracket position should relate to the pilaster rather than being fixed into the middle of a panel. And window vinyls covering the glazing defeat the purpose of reinstating a shopfront, so expect a condition limiting the proportion of glazing that can be obscured.

Drawings and evidence the authority needs

The commonest reason a reinstatement application stalls is that the drawings are at the wrong scale to show what matters.

1. Existing and proposed elevations at 1:50, with the whole building shown so the fascia depth can be read against the first floor cill.
2. Large-scale details at 1:5 or 1:2 through the fascia and cornice, the pilaster and console, the stallriser and the cill.
3. A plan at the threshold showing the recess, the door swing, the level arrangement and any surviving historic finish.
4. A schedule of materials, joinery sections, paint colours and finishes, with manufacturer references where relevant.
5. A photographic survey of the existing frontage and of the comparable surviving frontages used as evidence.
6. The historic evidence itself, reproduced at a legible size with its source and date.
7. A heritage statement assessing the significance of the building and the contribution of the frontage, then explaining how the proposal enhances the character of the area.

Where the building is listed, listed building consent is needed as well as planning permission, and the same heritage analysis supports both. Boundary and ancillary structures sometimes need their own consent, which is covered in the note on boundary walls, railings and gates.

Conditions and funding questions

Expect conditions requiring large-scale joinery details to be approved, paint colours to be agreed, sample panels or a mock-up where the detail is important, and the historic threshold or other surviving fabric to be retained and protected during the works. On a shopfront in a terrace the authority may also condition the signage separately from the frontage.

On funding, area-based grant schemes do exist and they come and go. Historic England has operated partnership schemes in conservation areas and high street heritage programmes, and some councils run their own shopfront improvement grants, sometimes tied to a conservation area appraisal or a town centre strategy. Ask the conservation officer what is currently open before you assume there is nothing, and ask early, because grant schemes usually require approval before works start rather than reimbursement afterwards.
