Quick Guide: Planning Permission for Steel Buildings

Quick Guide: Planning Permission for Steel Buildings.  We are always asked if planning permission of needed for new steel buildings, well the answer is generally YES.

So, the first thing you should do is talk to your local planning department

This can be done by arranging an informal discussion with your local authority planning department to discuss your new project.  You can often get a good indication from your planning office as to the possibility of obtaining your planning.

They will also be able to tell you if there will be any particular considerations to be taken into account such as rights of way, Bats, Tree preservation orders etc.

We advice you take a proposed plan with you inlcuding elevations and ground layout plans with measurements on, which we can provide for you when you get your FREE quote from us.  Please note that these drawings will not be the structural drawings at this stage they will just be general drawings which we have found are quite sufficient for planning officers.

Planning permission is often needed in the following circumstances:

Planning Applications
  • The new building is more than 4 metres high (with a pitched roof).
  • The application site is located in a conservation area, a national park or is next to a listed building.
  • If the new building is going to be located nearer the road than the house.
  • Building Regulation approval is required if your building is over 30 square metres
  • The new building is for commercial purposes.
  • As a general rule if you are replacing an old garage planning permission is not always required, but make contact with your local authority to be sure.

Planning Applications

To apply for planning permission, you have to send a planning application form and fee to your local authority. The planning application will be considered against local planning policies and any objections received from the public.

Planning approval may be granted outright, conditions may be applied (such as restricting the hours of use of business premises) or a planning application may be rejected. You can negotiate minor objections, submit a new application taking into account concerns raised by the local authority or appeal a decision that goes against you.

Carrying out a building project without planning permission can be disastrous. Although you may be able to apply for retrospective planning approval, you could face refusal and a requirement to demolish unapproved premises or cease activities that are not permitted.

Permitted Development

The erection, extension or alteration of an industrial building or warehouse is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions shown below.

Specific to new industrial buildings and warehouses:

  • No new building to be higher than 5m, if within 10m of the curtilage boundary. In other cases no new building to be higher than the highest building within the curtilage boundary or 15m – whichever is lower
  • No new building to exceed gross floor space of 100 square metres in designated land and sites of special scientific interest. In other cases 200 square metres.

Specific to extending or altering industrial buildings and warehouses:

  • No extension or alteration to make building higher than 5m, if within 10m of the curtilage boundary. In all other cases any extension or alteration must not be higher than the building being extended or altered.

Building Regulations

Under the building regulations, you normally require building consent for major building works: for example, new construction, significant extensions or structural alterations.

As with planning permission, going ahead without building approval can be very risky. You could face an order to demolish unsafe alterations or experience problems selling the premises, for example. Read about building regulations on the Planning Portal website.
