Metal Garages in Mansfield: Sizes, Bases and Planning Explained

Bespoke metal garage installed at a property in Mansfield

A metal garage gives Mansfield homeowners secure, dry storage in days rather than the weeks a masonry build takes — and at a fraction of the cost. The parts that decide whether you are happy with it are the size you choose and the base it sits on.

Here is how we specify, build and install steel garages and workshops across Mansfield and the surrounding Nottinghamshire area.

Choosing the right size for a Mansfield plot

We build to your measurements rather than fixed catalogue sizes, so a unit can be squeezed into an awkward Mansfield plot without wasting driveway space.

  • Single garage — one car plus storage down one side; the most common choice on estate plots
  • Double garage — two vehicles, or one car and a workshop bench
  • Oversized and long units — vans, caravans, boats and trade storage
  • Workshops and lean-to extensions where the garage doubles as a working space

The base is the part people underestimate

A steel garage needs a level, square concrete base at least as large as the building footprint. If the slab is out of level the doors will not sit true, so we set out the base dimensions at survey stage and can arrange the groundworks if you do not have a contractor.

Insulation, doors and finishes

  • Anti-condensation lining or full insulation where the garage will be used as a workshop
  • Up-and-over, roller shutter or personnel doors, plus windows where you need daylight
  • Powder coated steel in your RAL colour, matched to gates, fencing or existing joinery
  • Guttering and downpipes tied into the existing drainage

Planning permission around Mansfield

Most domestic garages fall under permitted development, but height, boundary distance and position in front of the principal elevation all matter — and conservation areas within Nottinghamshire have tighter rules. We tell you honestly on the survey whether we think you need to check with the local authority.

Installation across NG18–NG21

We deliver and install throughout Mansfield and nearby towns including Sutton-in-Ashfield, Kirkby-in-Ashfield, Warsop, Ollerton. A standard single or double garage is normally erected in a day once the base has cured; larger workshops and insulated units take two.

Frequently asked questions

How much does a metal garage cost in Mansfield?
Price is driven by footprint, height, door type and whether the unit is insulated. We quote in writing after confirming the size and base condition at a free survey in Mansfield.
Do I need a concrete base?
Yes. A level, square concrete slab is required for the frame to sit true and the doors to run correctly. We set out the exact dimensions before you order.
Do I need planning permission for a garage in Mansfield?
Many garages are permitted development, but height, boundary distance and conservation area status can change that. We flag anything that looks borderline during the survey so you can confirm with the council.
Can the garage match my gates and fencing?
Yes — we powder coat garages, gates, railings and fence panels to the same RAL reference so the whole frontage reads as one design.
