Co-working space in a former retail unit

Putting a co-working space into a former shop usually needs no co working space planning permission retail to office at all. Offices sit in Class E(g)(i) and shops sit in Class E(a), and a change between uses within the same class is not development. That is the starting point, and it surprises people who have read a local plan policy about protecting ground floor retail frontages, because those policies cannot bite on something that is not development in the first place.

What does bite is a condition on an earlier permission, physical works to the building, and the moment the business stops being an office.

Office and retail inside one class

The Use Classes Order was amended in 2020 to create a broad commercial, business and service class. Shops, cafes, offices, light industrial uses compatible with a residential area, gyms, clinics, nurseries and professional services all sit inside it.

Section 55 of the Town and Country Planning Act 1990 and the Order together mean that moving between uses in the same class is not a material change of use. No application, no fee, no consultation.

Two caveats that matter more than the rule.

A unit that was never in Class E cannot rely on this. Drinking establishments, hot food takeaways, betting offices, cinemas and launderettes are sui generis, and a change from one of those into a co-working space is a material change requiring permission.

And a condition restricting the unit to a named use survives the Order. A 1990s permission conditioned for use as a retail shop only still binds the building, however wide Class E has become. Search the planning history before signing a lease. This is the single most common reason a co-working project that needed no permission turns out to need one.

Frontage policies that still have teeth

Authorities worried about hollowed-out high streets write policies requiring active frontages and resisting the loss of retail at ground floor level. Those policies apply when a decision is being made. They have nothing to work on when no decision is required.

Where they do apply is in three situations.

Physical alterations. A new shopfront, roller shutters, a replacement entrance or an altered fascia all need permission where they materially affect the external appearance, and the officer will assess them against the frontage policy. A solid shopfront with frosted glazing on a primary shopping frontage will be resisted. A design keeping the window active and transparent will not.

New development. Where the co-working space forms part of a new building or a larger change, the policy applies to the whole.

Conditions on a recent permission. Where the unit was consented within the last few years, the permission may restrict the use or require the frontage to be retained in a particular form.

Design the frontage to work with the policy anyway. A co-working space with a visible café counter, a staffed reception and lit glazing contributes to a street in the way the policy intends, and that argument is worth making even when no permission is needed, because it shapes how the authority treats the next application.

Where the use shifts out of Class E

This is the question that decides whether a co-working business stays out of the planning system.

A café serving members and visitors is within Class E and is unproblematic. Meeting rooms, podcast booths, event space used during working hours for business purposes, and a members' bar operating as an ancillary part of the office use are all arguable within the class.

The shift happens when the evening use stops being ancillary. A space hosting ticketed events three nights a week, with a public bar, late hours and a door policy, is operating as a drinking or entertainment venue in substance whatever the daytime use is. That is a material change of use to a sui generis use or to a mixed use, and it needs permission.

The test is one of fact and degree: frequency, hours, who attends, how it is marketed and whether the activity could continue without the office use. Keep the evidence, because enforcement investigations into this exact scenario usually start with a social media listing. Our note on micro-pubs in former shop units covers the route if the evening use is the actual business model, and the piece on escape rooms and experience venues in retail units covers the adjacent question for daytime leisure uses.

Alcohol sales need a premises licence under the Licensing Act 2003 regardless of the planning position, and the two regimes are independent. A licence is not permission and permission is not a licence.

Cycle parking, showers and end-of-trip facilities

Where no permission is needed, cycle parking standards cannot be imposed. Provide them anyway, because members expect them and because retrofitting a shower into a shop unit later is expensive.

The planning consequence arises if the facilities need building works. A rear extension to house changing rooms needs permission. Secure cycle storage in a rear yard may need permission depending on size, siting and whether the yard is enclosed. In a conservation area, external cycle storage visible from the street will be assessed on appearance.

Think about where bikes go on day one. A unit with no rear access and no forecourt will end up with bikes inside, which affects the layout and the fire strategy.

Plant, ventilation and cooling on a shopfront building

Co-working densities are higher than shop densities, and the ventilation and cooling load goes up accordingly. The condensers have to go somewhere.

A roof-mounted unit on a two-storey building with flats above or behind is both a visual and an acoustic question. Permission is usually needed for external plant, and in a conservation area or on a listed building the bar is higher.

Where residential windows are within sight or earshot, a short assessment settles it before environmental health raises it. A Noise Impact Assessment comparing the rating level with the measured background at the nearest residential facade is the standard evidence, and specifying a quieter unit at procurement is almost always less expensive than attenuating a noisy one afterwards.

Internal noise matters too. Meeting rooms and phone booths against a party wall with a flat above a shop will generate complaints, and the acoustic separation needs designing rather than assuming.

Conditions worth protecting

If you do end up making an application, for the shopfront or for plant, watch the conditions that come back.

The one to resist is a condition restricting the premises to use within Class E(g)(i) only. That removes the flexibility the Order otherwise gives and binds the unit for the life of the permission, which matters when the business model changes or the space is relet.

Equally, a condition tying the use to a named operator or a membership model is unnecessary and usually fails the tests for conditions. Ask for it to come out, with a reason.

Where you want the position recorded formally, a lawful development certificate for a proposed use is the only way to confirm that the use is lawful, supported by a short Planning Statement setting out the use class analysis and the planning history.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
