Getting permission for a garden centre with a cafe

A garden centre is retail development, and that is the sentence that decides most applications. Garden centre planning permission is usually refused or granted on the retail tests rather than on the glasshouses, because the moment a site sells a material quantity of goods it did not grow, it has stopped being a horticultural nursery and become a shop in the countryside. Add a cafe and a coach park and the policy weight shifts again.

Growing and selling are different uses

Section 336(1) of the Town and Country Planning Act 1990 defines agriculture to include the use of land as a nursery ground and for horticulture. Raising plants for sale is therefore agricultural.

Selling plants someone else raised is retail. Selling furniture, barbecues, pet food, clothing and Christmas decorations is plainly retail, and under the Use Classes Order as amended in 2020 the retail sale of goods sits in Class E. Most garden centres are a mixture, and the planning question is where on that spectrum the operation sits and whether the mix has changed materially since the last permission.

A nursery that grows its own stock and sells it from a timber shed is an agricultural holding with ancillary sales. The same site, after twenty years of incremental growth, selling mainly bought-in goods across 1,800 m² of covered sales area, is a retail unit, and the change happened without anyone applying for it. That is the position a great many sites are quietly in, and it matters because enforcement and any future application both start from what is lawful rather than from what exists.

Set out the actual trading position in the Planning Statement: sales floorspace by category, the proportion of stock grown on site, and the trading history with its permissions.

The sequential test for an out of centre site

Retail is a main town centre use. Where a proposal for retail development is not in a defined centre and is not in accordance with an up-to-date development plan, national policy requires a sequential approach, so you have to show there are no suitable, available and viable sites in a centre or in an edge of centre location before an out of centre site can be considered.

Garden centres argue their way through this on the basis of the floorspace they need, the outdoor growing and display area, the vehicle access for deliveries and the fact that customers transport bulky plants by car. Those arguments can work, and they work much better when the assessment is honest about the sequential sites it looked at and why each was discounted. A Sequential Test that dismisses town centre sites in a sentence is the one that gets challenged.

An impact assessment is required for retail development above a threshold, with national policy applying a default of 2,500 m² of gross floorspace where the local plan has not set its own figure. Many plans set a lower local threshold, so check the adopted plan first. Where the threshold is crossed, a Retail Impact Assessment addressing the effect on existing centres and on planned investment is needed, and councils normally expect a suitably qualified author.

Green Belt adds another layer entirely, and a significant number of garden centres sit in it. Buildings and hard surfacing in the Green Belt engage the question of inappropriate development, and the case has to be built on the exceptions and, if necessary, on very special circumstances.

When the cafe stops being ancillary

A tea room serving customers who came to buy plants is ancillary to the retail use and needs no separate consent. A destination restaurant does.

Authorities look at a cluster of indicators rather than at floorspace alone.

The practical risk is drift. A cafe approved as ancillary that later opens for evening meals has changed use, and the authority finds out when a neighbour complains about car doors at 10pm. If the intention is a cafe that trades independently, apply for it on that basis, because retrospective applications on a site already generating complaints are much harder.

Extraction is the other half of this. A commercial kitchen on an open countryside site still needs an extract route, odour control and a flue that does not dominate the elevation.

Polytunnels, canopies and outdoor display

Whether a polytunnel is a building depends on its size, permanence and degree of attachment to the ground, and the courts have accepted that a structure erected for most of the year can be a building even if it is theoretically moveable. So the comfortable assumption that tunnels are not development is unreliable, particularly for large commercial spans on concrete pads.

Where the holding is still agricultural and large enough, Part 6 of Schedule 2 to the General Permitted Development Order 2015 may cover some of it, subject to its purpose test and limits. Once the site is retail rather than agricultural, Part 6 is unavailable and every tunnel, canopy and covered sales area needs permission.

Outdoor display is the visual issue officers raise most. Stacked pallets, banners, inflatable signage and seasonal stock to the roadside boundary do more harm to a rural landscape case than the buildings, and a landscape and display strategy, with a condition you can live with, is worth offering.

Parking, coaches and the spring peak

Trade is violently seasonal. Easter and the spring bank holidays produce peak demand several times the annual average, and sizing parking on an average day produces a car park that spills onto the lane twice a year.

Assess the peak. Where the site draws coach trips, show the coach standing and turning area with a swept path, and keep coach movements away from the customer trolley route. Trolley routes across a car park are a real safety point and officers raise them.

Delivery traffic runs on a different cycle, with bulk plant deliveries in late winter and spring, and articulated vehicles on a rural access need the same swept path treatment.

Surface water from a lot of hardstanding

Garden centres cover large areas with hardstanding, glass and polythene, and all of it sheds water fast. The run-off case is often the quiet reason a scheme is held up.

Permeable surfacing for parking, swales along the boundary planting, attenuation storage sized on a tested critical duration, and discharge restricted to a greenfield equivalent rate are the usual components, and they need setting out in a Drainage Strategy. Glasshouse roofs are worth treating separately, because clean roof water is the easiest flow to attenuate or harvest for irrigation.

Irrigation abstraction is a separate consent question where water is taken from a borehole or watercourse, and it sits with the Environment Agency rather than the council.

Conditions on the goods sold

Expect a condition restricting the range of goods, and negotiate its wording carefully, because it will govern the business for decades.

The common forms limit sales to horticultural and associated goods, cap the floorspace or proportion given to non-horticultural lines, or define a maximum net sales area. A condition drafted tightly around a 2026 product range will be a problem in 2032, so argue for a definition by category and a stated proportion rather than a list of permitted products. Also expect conditions on hours, on external display, on lighting and on the cafe remaining ancillary.

Ask for the wording you want in the covering submission. It is far easier than a section 73 application two years later.
