Business units and light industrial.

Small business units need to work for vans, rigid lorries and the occasional articulated delivery. We design the access and yards so they do.

The occupiers of small units are often unknown at application stage, so the layout has to cope with a range of businesses and vehicles without causing problems on the road.

What the council focuses on

The largest vehicle likely to visit, turning space within the site so vehicles leave forwards, parking for staff and visitors, and the effect of HGVs on nearby roads.

The evidence that answers it

Trip generation for the mix of uses proposed.
Swept paths for the design vehicle in each yard.
A parking layout that keeps service areas clear.
Access design and visibility.

Workshops and studios

Workshops, makers’ studios and creative spaces generate light servicing and staff trips. We keep the evidence short where the use is low in intensity.

What the application usually needs

A Transport Statement with trips by car, van and HGV.
Access design with swept paths for the largest vehicles.
Parking and servicing for each unit.
Cycle parking and walking routes.
Flexibility across the uses proposed.

A typical case

A typical case is ten small business units on a rural employment site, for workshops, trades and light industry. The council asks about lorries on the approach road. We base trips on TRICS industrial estates, show that most vehicles are cars and vans, design the access for a rigid lorry, and give each unit a loading area so vehicles do not park in the estate road.

Technical points

Units marketed for flexible uses need assessment against a reasonable worst case. Servicing is the main design issue: we size yards and loading areas for the vehicles each unit will use, and check that the estate road can carry occasional articulated vehicles. See our insight on servicing small business units.

If highways raise concerns

Concerns usually relate to lorries on rural roads, servicing in the estate road and parking. Designing the access for the right vehicle and giving each unit adequate yard space usually resolve them.

Where the council wants to limit the uses or vehicle sizes, a condition can do this without preventing the scheme.

How we help

We provide the transport statement and layout checks, and agree a design vehicle with the highway authority at the start.

The same questions arise in Scotland and Wales, where they are assessed against NPF4 and Scottish guidance or Planning Policy Wales and TAN 18 rather than the NPPF.

FAQ

Questions we get asked

Do small business units need a Transport Statement?

Often, especially on rural sites. It covers trips, access and servicing.

How are trips worked out for flexible units?

From TRICS data for comparable estates, testing a reasonable worst case among the uses sought.

Will the access need to take articulated lorries?

It depends on the likely occupiers. We design for the largest vehicle expected.

How much parking does each unit need?

It depends on the use and the council’s standards. We size it with servicing in mind.

Do rural workshops raise different issues?

Mainly the approach road and access. See our farm diversification page.
