Will two cars actually fit?

A 6×6 takes two family cars side by side behind two doors. Go up to a 7×6 if either car is an SUV, or if you want to walk comfortably between them and still have a working strip behind. Internal dimensions depend on the roof profile, height build and door layout you configure. Full dimensioned drawings are supplied with your order confirmation before anything is manufactured, and we confirm vehicle fit with you before you commit.

Questions

Before you commit

What exactly is included in the price?

The headline price is the total price for the building, including delivery to your address and full professional installation. It does not include groundworks or a concrete base (priced separately: a guide price from your photos, then a firm quote after our contractor's site visit), or any electrical upgrades (those are selected and priced in the configurator). There are no hidden charges for standard sites.

Is a base included, and what does one cost?

Your building is installed on a level, load-bearing base of the correct size. Providing that base is your responsibility and it is not included in the price. You can prepare it yourself, use your own contractor, or have VeltHaven Foundation Management design and build it for you: a guide price from your photos, then a firm quote after our contractor's site visit. As a guide, Foundation Management, our fully managed service, costs from £5,495 to £8,695 for a garage base for cars and storage (125 mm slab) and from £5,095 to £6,295 for a garden-room base, depending on size, ground conditions, levels and access. Built by your own groundworker, a base typically costs £1,900–£8,100 for a steel garage and £2,500–£10,800 for an insulated garage, excluding VAT. Add VAT if your contractor is VAT-registered.

Do I need planning permission for a steel garage?

It depends on which height build you choose, which roof, and where it sits on your plot. In England and Wales an outbuilding is normally permitted development if it is single-storey, sits behind the front of your house, and — within 2 m of a boundary — is no more than 2.5 m tall overall. Set further back, the limit is 3 m overall for a mono-pitch roof or 4 m for an apex roof, with eaves no higher than 2.5 m in either case. Our rear-pitch roof is a mono-pitch roof in those terms. Measured against that, the Standard build (248 cm (8′2″) externally) is normally within permitted development set back from a boundary with either roof, and with a rear-pitch roof close to a boundary as well. The SUV build (268 cm (8′10″) externally) is above the 2.5 m line close to a boundary; set further back a rear-pitch SUV is inside the 3 m overall cap, but its front eaves are above 2.5 m, so that one is worth confirming with your local planning authority — and an apex SUV is above the eaves limit wherever it sits. The VAN build (368 cm (12′1″) externally) is above every limit, so it needs a planning application on any plot. Permission is also more likely to be needed in a conservation area or on a listed building, or if previous extensions have already used up your permitted development allowance. Rules differ in Scotland and Northern Ireland, and permitted development does not apply to flats or maisonettes. Send us your boundary distances and we'll flag what's likely to apply — your council has the final word. Read our full planning guide →

How long does it take from order to finished garage?

We deliver and install within 8 weeks of your full payment, and that includes manufacture: your building is made to order, which takes 4–6 weeks depending on specification. Once it is ready and your concrete base is in place, delivery and installation take a steel garage usually 1–2 days, an insulated garage or garden room 1–3 days, weather permitting. Your building goes up first. Our electrician then attends on a separate scheduled visit, and any climate, flooring, security or EV work is booked in after that — each on its own visit, arranged with you. We confirm your installation date once your deposit is paid and your site photos have been reviewed.

What is the VeltHaven 10-Year Structural Warranty?

Every steel garage includes a VeltHaven 10-Year Structural Warranty: 2 years full warranty + structural cover to year 10. This is self-backed by VeltHaven Ltd (Companies House 17261887). It does not affect your statutory rights under the Consumer Rights Act 2015.
