Double Garages

A double garage is a garage wide enough to take two cars side by side, normally 16ft or more across. Nucrete doubles start at 16'5" wide and go up to 20'5", in lengths from 14'3" to 24'3". Plenty of owners use the width for one car and a workshop rather than two cars.

For two cars in comfortably, with room to open doors on both sides, look at 20'5" × 20'3" (roughly 6m × 6m). A 16'5" wide double will take two small cars but you'll be breathing in. If you also want a bench or storage down one side, go up a size on width rather than length.

It depends on three things: the size, whether you choose an apex or pent roof, and where you're building. A pent roof is the more economical of the two, and prices vary by delivery area because delivery and installation are included in every price rather than added at the end. Enter your postcode area on this page and you'll see the exact price for the size you're looking at, or request the price list and we'll send the full set.

Often not. Permitted development rights generally allow an outbuilding up to 2.5m high if it's within 2m of a boundary, and it must not cover more than half the garden. A single-storey double garage usually falls inside that. Listed buildings, conservation areas and front gardens are the common exceptions — tell us your situation and we'll say honestly whether you need to check with the council.

Estate agents generally reckon a garage adds more to a property than it costs to build, and a double more than a single, because it also solves storage and off-street parking. The effect is biggest where street parking is difficult. It's a general pattern rather than a guarantee — your local agent will know your street better than we do.

They're different rather than one being better. Concrete doesn't rot, doesn't need treating every year or two, lasts 50 years or more and carries our 10-year structural guarantee. Timber looks warmer and can be cheaper as a self-assembly kit, but it needs maintaining and has a shorter life. If you want a building you can forget about, concrete is the easier ownership.

Clear span — open plan — gives the most usable space and the most room to open car doors, so it's the usual choice for parking two cars. A centre dividing wall suits splitting the building into a garage and a separate workshop or store, or sharing a double across a boundary with a neighbour.

Most double garages are installed in a day by our own teams. From order to installation is normally four to six weeks. The base is always a separate, earlier visit — new concrete has to cure for at least a week before your building goes on it, so the two jobs are never done the same day.

A flat, level, square concrete base at least 100mm thick, roughly 150mm wider and longer than the garage. We can lay it for you after a free survey, and if we lay it the building is guaranteed to fit it. If you'd rather use your own builder we'll happily liaise with them on the specification so it's right first time.

50 years or more with only basic annual maintenance — keeping the gutters clear and an eye on the timber fascias. The steel-reinforced panels don't rot or rust through, and the structure carries our 10-year factory guarantee from the day it goes up.
