What does a steel building cost?

The cost of a steel building can vary and depends on a number of factors such as size, material, location, etc.

For example, we recently quoted a double garage (6m x 12m x 2.6mH, single skin steel with two roller doors and one PA door) at just over £8 000, excluding VAT and erection costs; and a warehouse facility (30m x 28m x 5.3mH, single skin steel with three roller doors, two PA doors and skylights) at approximately £94 000 excluding VAT and erection costs.


Do I need planning permission?

That depends on both the size, purpose and location of your building. The best point of contact for this information is your local planning authority at your local council.

You can find out more information about planning requirements and the contact details for your local planning authority at the Planning Portal website here.


What grounds work do I need to do beforehand?

You must have a a secure and stable surface on which to erect your steel building. This should be a minimum thickness concrete pad that allows the wall cladding to overlap and allow rain water to run off and not leak into the building; or individual concrete pads for the steel columns to be fastened to. We will provide you with the specification for the base when your purchase your building.

Alternatively, CASTLE STEEL BUILDINGS can provide a grounds work service for you if you require, which will ensure you have a high quality, durable and suitable surface for your building.

What the difference between single skin and composite?

Single-Skin Steel Cladding roof and wall systems consist of coated steel sheets rolled to five different profiles. They may be used to form roofs and walls and include a comprehensive range of fixings, sealants, guttering, flashings and rooflights.

The AS Single-Skin Steel Cladding system offers rapid coverage and swift completion of a weatherproof building envelope to give a high performance building. (more…)

Composite cladding panels are insulated steel cladding which consists of two coated steel profiles bonded to a core of PIR insulation; they may be used to form roofs, down to a 4 degree pitch, and walls. The external faces have clean, sharp lines and the panels are available in an extensive range of finishes and colours. (more…)

Can I erect the steel building myself?

If you wish to construct the building yourself we provide a handover document that details all of the connections and fittings for your building, however we provide an optional erection cost with all our quotes and we would STRONGLY advise you let our qualified and experienced erection team construct the building on site for you. With 25+ years experience it will give you peace of mind and also leave you covered if you need any after sales service.


What’s the biggest steel building you can make?

The widest single frame we can erect is 20 metres, although we can combine frames from multiple buildings and remove interior walls to create a wider overall building as necessary.

There is no limit to the length of building we can provide.


What’s the highest your steel buildings can go?

Our steel buildings can reach as high as 6 metres to the eaves. The ridge height will vary depending on the pitch of the building.


Why do you need the site post code?

Our design process takes into account things like distance from the sea, topography and altitude above sea-level to factor in wind resistance and also snow loading requirements.

By providing the postcode for your building site we can design a building that takes account of these additional elements to make sure you have a building fit for purpose.


What’s the difference between an industrial building (Class 1) and an agricultural one (Class 2)?

Great care must be taken when determining the usage or classification of a building. The dead loads (snow loads) that agricultural buildings can withstand are significantly less than for the industrial classification.

Classification in British Standards are:
Industrial Class 1 – Human occupation is unlimited, and there is no minimum distance restriction from other occupied building or highways. Be mindful that boundary conditions may apply and a fire boundary required. Minimum design life 50 years
Agricultural Class 2 – Human occupation not to exceed 6 hours per day at a maximum density of 1 person per 100 sq m. Building must be greater than 20 metres from nearest occupied building and or highway. Minimum design life 10 years.
