Replacing a historic shopfront: the consents involved

Replacing a shopfront on a historic building usually needs more than one consent, and the application that fails is almost always the one that dealt with a single consent and assumed the rest would follow. On a listed building in a conservation area with an internally illuminated fascia sign, you are looking at planning permission for the alteration, listed building consent for the works to the building, and advertisement consent for the signage. Three applications, three tests, and only one of them is about design in the way a shopfitter would understand the word.

Which consents apply

Planning permission is needed for alterations that materially affect the external appearance of the building, which a new shopfront does. Listed building consent is needed under section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990 for works that would affect the character of the building as one of special architectural or historic interest, and on a shopfront that includes internal works behind the frontage.

Advertisement consent runs under the Town and Country Planning (Control of Advertisements) (England) Regulations 2007 and is assessed on two grounds only: amenity and public safety. Some signs benefit from deemed consent under Schedule 3 to those regulations, subject to the size, position and illumination limits in the relevant class. Many fascia signs on ordinary shops fall within a deemed consent class, and the same sign in an area of special control, or internally lit in a sensitive location, will not.

The practical rule is to check the deemed consent classes before designing the sign, not after. The limits in those classes are what a sign has to be designed around if you want to avoid a third application.

What survives and what you are allowed to lose

Before drawing anything, establish what of the original shopfront is still there. On a nineteenth or early twentieth century frontage, survival is usually partial: pilasters and console brackets behind later cladding, a stallriser under a modern panel, an original fascia board under a box sign, curved glass in a lobby, a mosaic threshold.

Those elements are the ones a conservation officer will expect to see retained and repaired. Removing them is what turns a straightforward application into a refusal, and the removal frequently happens during strip-out before anyone has looked. Open up carefully and record what is found, because the record supports the application.

A Heritage Statement should set out what survives, what is later, and what the proposals do to each. Where original fabric is hidden behind later work, say so, because the assessment changes completely depending on whether the frontage is an intact historic shopfront or a 1980s replacement in a historic building.

Proportions that officers assess

The traditional shopfront is a designed frame, and the parts have relationships that survive being explained. The stallriser lifts the glazing off the pavement, giving the display a base and the glass some protection. Pilasters at each side carry the visual load of the wall above. The fascia sits between them, capped by a cornice, and its depth is limited by the level of the first floor windows. Get the fascia depth wrong and the whole elevation looks wrong, which is why officers measure it.

Three errors recur. A fascia that runs across two or more buildings, destroying the plot rhythm of the street. A fascia that rises above the cill of the first floor windows. And a shopfront that removes the stallriser entirely, so the glass runs to the pavement and the building appears to float.

Where the building is in a conservation area, the duty under section 72 to pay special attention to preserving or enhancing character applies to the whole street scene, not just the unit. Our note on what sections 66 and 72 require of decisions covers how that duty is applied.

Signage and illumination

Amenity and public safety are the only two grounds, but in a conservation area amenity does a lot of work. Internally lit box signs and acrylic panels are the applications that fail most often. Externally lit painted or applied lettering, with discreet trough lighting or swan neck lamps, is the form most often approved.

Practical points worth settling early: lettering applied directly to the fascia rather than mounted on a panel reads better and is usually cheaper to consent; projecting signs are generally limited in size and projection by the deemed consent classes, so check the dimensions against the class before fabricating; and illumination levels should be stated in the application, because an officer who has to guess will assume the brightest option.

Express advertisement consent is normally granted for a fixed period by standard condition, so diarise the expiry rather than discovering it at a lease renewal.

Security shutters and the alternatives

Solid external roller shutters with a box above the fascia are the single most commonly refused element of a shopfront scheme in a historic area. They read as a dead frontage at night, they obscure the architecture, and the housing box usually cuts across the fascia and cornice.

The alternatives that get consent are open lattice shutters where the boxes can be concealed internally, internal shutters or grilles set behind the glass line, laminated security glazing with no visible protection at all, and removable overnight grilles. Each of these costs more than a solid shutter. Each also avoids a refusal and a second application.

Access and thresholds

A shopfront replacement is the natural moment to deal with a stepped entrance. Level or ramped access is expected on a new shopfront wherever it can be achieved, and the service provider duty to make reasonable adjustments under the Equality Act 2010 applies independently of planning.

On a historic frontage the usual conflict is between a level threshold and the retention of the original stallriser and door position. The workable answers are internal ramping behind the door line, a shallow external ramp within the existing recess, and, where the pavement gradient allows, a rebuilt threshold at the new level using the original materials. What does not work is an application that ignores the point, because an officer will raise it.

Assembling the application

1. Survey and photograph the existing frontage, including what is found behind later cladding during any opening up.
2. Draw the existing and proposed elevations at the same scale, with a section through the fascia and cornice and details at the pilasters.
3. Prepare a signage schedule giving dimensions, materials, lettering, illumination type and luminance, and check each sign against the deemed consent classes.
4. Set out the heritage justification, describing the effect of each intervention on what makes the building interesting.
5. Submit the planning, listed building consent and advertisement applications together so they are assessed as one scheme.
6. Agree a strip-out protocol with the contractor that stops work if unrecorded historic fabric appears.

Where the works go beyond the frontage and affect the interior, our note on internal alterations that harm significance covers the tests applied inside the building.
