Walkthrough: flats above a parade with no parking

A car free flats parade application lives or dies on two things that have nothing to do with the flats themselves: whether the highway authority believes the occupiers will not own cars, and whether the bins and bicycles fit. This walkthrough follows an illustrative scheme of six flats formed in vacant first floor storage above a 1930s shopping parade, in a controlled parking zone, 400 metres from a railway station. Every figure in it is illustrative. The design points, the objections and the order of work are the parts worth taking away.

The building and what was there

Six shops at ground floor, each with ancillary storage above reached by a rear stair from a shared service yard. The upper floor had been empty for several years, used for nothing more than old fittings.

The yard is 6 metres deep, shared with the shops, and contains the shops' own waste. The rear elevation faces north-east across the yard to a 2.4 metre boundary wall and the rear gardens of houses beyond. The front elevation faces the high street.

That geometry sets the three constraints the whole scheme works around. Single aspect rooms to the rear get limited daylight. The yard has to hold residential refuse, residential cycle parking and commercial waste at once. And the flats sit directly above trading premises, one of which is a hot food takeaway with an extraction duct on the rear wall.

Prior approval against a full application

Upper floor storage ancillary to a shop sits within the shop's planning unit, and Class E now covers retail. Class MA of Part 3 permits a change from Class E to residential use subject to prior approval, and it can apply to part of a building.

The class carries its own gates: the building must have been in Class E use for a continuous period before the application, must have been vacant for a shorter continuous period immediately beforehand, must fall within the floorspace limit, and the new dwellings must meet the nationally described space standard with adequate natural light in all habitable rooms. Those conditions have to be checked against the current text of the Order, and the vacancy and prior use evidence has to be assembled before applying.

Prior approval matters under Class MA cover transport and highways, contamination, flooding, noise from commercial premises, adequate natural light, and the impact of the loss of ground floor services in some circumstances.

Our illustrative scheme went the full application route instead, for a specific reason. Two of the six flats could not reach the space standard without taking part of a shop's storage that the tenant wanted to keep, and a full application allowed a four flat scheme with better rooms and a negotiated car free obligation. Prior approval would have been quicker and would have delivered worse flats.

Making the car free case

The policy argument is straightforward where the evidence supports it. National policy supports maximum parking standards set with regard to accessibility, the availability of public transport and local car ownership levels, and town centre sites above shops are the clearest case there is.

The supporting statement set out walking distances to the station and to three bus routes, measured along actual pedestrian routes rather than as straight lines, with a plan. It gave local car ownership from published census data for the output area. It described the daily needs within walking distance: a supermarket, a surgery, a primary school.

Then it conceded the obvious. A car free scheme does not stop an occupier owning a car. It stops them parking it legally on the street, and only if the permit restriction actually works.

The overnight parking stress counts

The highway authority asked for stress surveys before it would engage, and the scope was agreed in writing first: streets within a 200 metre walk, two nights covering one midweek and one weekend, counts in the small hours, usable kerb length calculated after deducting crossovers, junction protection and loading bays, and the survey outside school holidays.

The counts came back high, which was expected on a town centre street inside a controlled zone. The useful number was not the occupancy at all. It was the permit data obtained from the council: permits on issue against usable spaces, and permits against eligible households in the zone.

Where a zone is already oversubscribed, no survey rescues the application. The answer has to be a restriction, and the restriction has to bind.

Cycle parking and refuse in a yard that is too small

This is where most parade conversions actually fail, and it is a drawing problem rather than a policy one.

The requirements stacked up like this:

1. Secure, covered, long-stay cycle parking at the local standard per flat, in a store that does not require a bicycle to be carried through a flat or up the only stair.
2. Residential refuse and recycling containers sized for the number of units and the collection frequency, kept separate from the commercial waste.
3. A carry distance from each flat to the bin store, and a pull distance from the store to the collection point, within the distances in building regulations guidance and the council's own waste storage standards.
4. Space for the shops to keep trading, with their own waste and deliveries.

The resolution was a purpose-built store along the boundary wall, with the cycle store at one end and bins at the other, a green roof over both to answer a drainage condition, and a timetabled arrangement with the shop tenants on collection days. It cost two parking spaces that the scheme was not going to have anyway.

Daylight and noise to the rear facing rooms

Three of the four flats were single aspect to the rear, facing a boundary wall across a narrow yard. The daylight work went in early rather than as a response to an objection, because the layout depended on it.

The fix was conventional and effective: habitable rooms arranged to the front and to the wider part of the yard, bathrooms and circulation placed against the worst wall, a light-coloured finish to the boundary wall and larger openings where the structure allowed. The approach is the same one set out in daylight to single aspect flats and how to fix them, and the calculation sits in a daylight and sunlight assessment.

Noise needed two separate pieces of work. Airborne and structure-borne noise from the trading floors below, which is a building regulations and construction detailing question as much as a planning one. And the takeaway's extraction fan on the rear wall, assessed against the prevailing background level, with the duct extended above eaves level and attenuators specified. Odour from the same duct was dealt with alongside it. That work belongs in a noise impact assessment prepared by a suitably qualified acoustician.

The pack and the highway response

The submitted pack contained the planning statement, design and access statement, existing and proposed drawings including the yard layout at a readable scale, the parking stress survey with its marked-up plan, the permit data obtained from the council, the daylight assessment, the noise assessment, and draft heads of terms for a permit free obligation.

The highway authority's response accepted the car free principle and asked for three things: an increase in cycle parking, a condition requiring the cycle and bin stores to be provided before occupation, and the permit restriction secured by agreement rather than condition, since a condition cannot bind the permit scheme.

That is the pattern to expect. The parking argument is usually winnable above a parade. The storage, the daylight and the noise from the business downstairs are what decide whether the flats are any good.
