Bin storage requirements for flat conversions

Bin store requirements for a planning conversion are set by the council's waste service, written into a supplementary planning document or a separate waste storage guide, and applied by a consultee who is not the planning officer. That is why so many otherwise sound conversions come unstuck on refuse. The applicant reads the local plan, the local plan says storage should be adequate and well designed, and the waste team then asks for 3.2 m2 of enclosed store within 10 metres of the kerb that the drawings have no room for.

Find the standard before you draw the layout. It is almost always a downloadable document on the council's website under waste and recycling or under planning guidance, and it will give a figure per dwelling, a container type, and a collection arrangement.

Why waste storage refuses conversions

A house converted to four flats produces roughly four times the container demand of the house it replaced, in a building that was designed with a single dustbin by the back door. The store has to go somewhere, and the front garden is usually the only somewhere available.

Officers then have two objections in front of them. The waste team says the provision is short of the standard or the collection point is too far. The urban design or conservation officer says a brick and timber enclosure in the front garden of a Victorian terrace harms the character of the street. Solving one worsens the other, which is why the store should be designed at the start rather than added after the first officer comment.

The problem is sharper on Class MA office to residential conversions, where the prior approval route limits what the council can consider but the building often has no external servicing space at all.

Where the standards live

Look in three places, in this order.

1. The council's waste storage and collection guidance, usually issued by the waste or environmental services team. This gives litres per dwelling, container sizes, collection frequency and the drag and access distances.
2. The adopted local plan and any residential design or conversions supplementary planning document, which will carry the design expectations for enclosures and their siting.
3. The local validation checklist, which tells you whether a separate refuse statement or a plan annotated with the store is required for the application to be registered.

Where the council has nothing published, the recognised fallback is BS 5906, the code of practice on waste management in buildings. It is the source of most of the distance figures councils quote, and citing it gives an officer something to agree with.

Capacity, containers and frequency

Capacity is normally expressed as litres per dwelling per week, split between residual waste, mixed dry recycling, food waste and, in many areas, glass. Multiply the per-dwelling figure by the number of flats, divide by the collection frequency, and round up to whole containers.

Container choice follows from the number. Two or three flats usually take individual 240 litre wheeled bins. Four or more often move to shared 1,100 litre Eurobins, which need a wider store, a level threshold and a door leaf wide enough to roll them through. Food waste needs its own small caddy arrangement, and glass is heavy enough that a separate low container is usually preferred.

Two details get missed. Fortnightly residual collections double the storage requirement compared with weekly ones, and many authorities have moved to fortnightly. And the store has to hold every stream at once, rather than the average across a cycle.

Check whether the council will collect from a private forecourt at all. Some authorities will only collect from the adopted highway, which means the containers have to be presented at the kerb by somebody on collection morning, and the officer will want to know who that somebody is. Where the building is being sold as individual leasehold flats with no managing agent, that answer is harder than it sounds.

Storage also has to work in a fire. A bin store in an escape route, under a window, or against a timber fence on a boundary invites a comment from building control and sometimes from the fire authority, and moving it after permission usually means a non-material amendment application.

Carry and drag distances

Three distances decide whether a store is acceptable, and they pull in opposite directions.

These figures come from BS 5906 and are reproduced in most council guidance, but they are not universal. Some authorities apply a shorter drag distance for 1,100 litre bins because of the weight, and some apply a longer carry distance where a lift serves the store.

Surfaces matter as much as the numbers. The drag route must be level or gently ramped, hard-surfaced, at least the width of the container plus clearance, and free of steps, kerbs and gravel. A store 6 metres from the pavement with three steps in between fails as surely as one 30 metres away.

Cycle and bulky waste storage

Councils increasingly ask for cycle parking in the same breath as bin storage, and the two often compete for the same side passage. In London the London Plan sets minimum long-stay cycle parking for residential development, generally one space for a studio or one-bedroom flat and two for larger units, and boroughs outside London set their own figures in parking standards documents.

Cycle storage must be secure, covered, and accessible without lifting a bike over a bin. Two-tier racks are acceptable in larger schemes and awkward in a converted house, where a simple lockable shed usually reads better.

Bulky waste is the forgotten one. Where the council operates a bulky collection service, show a temporary standing area. Where it does not, expect an officer to ask what happens when a tenant leaves a mattress in the front garden.

On conversions of four flats or more it is worth adding a small parcel and delivery consideration too. Not a policy requirement in most areas, but a covered recess by the entrance keeps packaging out of the bin store and reads well in the design statement.

Showing the store on your drawings

Do not describe the store in text and leave it off the plans. Officers approve what is drawn.

Include a block plan showing the store position, the collection point at the kerb, and the drag route with its length annotated. Add a store plan at 1:50 with each container drawn to its real footprint, with the door swing and clearance shown. Add an elevation of the enclosure with materials named, and a section if the ground falls. Note the capacity calculation on the drawing: number of flats, litres per flat, collection frequency, containers required, containers provided.

Where the validation list asks for it, a short Waste Management Strategy carries the calculation, the container schedule, the collection arrangement and the management responsibility for moving bins on collection day. On schemes where design is the sticking point, the same reasoning belongs in the Design and Access Statement, explaining why the enclosure sits where it does and how it responds to the street.

One practical tip. Where the front garden solution looks poor, offer a managed arrangement instead: containers held in a rear store and presented at the kerb by a named managing agent on collection day, secured by condition. Several authorities accept it, and it saves the enclosure argument entirely.
