Convert Double Garage

Not at all. You'll get a securoglide door for about £1700 fitted. Looking at it, it looks fairly modern so I'm guessing not actually that wide? About 16ft of door needed? I have no idea about the other costs though but even getting someone in must be quite cheap to do it.

It sounds like I should be expecting quotes around £2.5k depending on the door I choose.

Not if you're going to retain the lateral stiffness of the garage.

Garage door would be anything from £1k to £1500 for a electronic roller shutter. I'd also allow £1.5k to £2.5k for beam installation. The beam could be £500 on its own.

£2k electric door, insulated door with steel. Fitted.

This. Did the same thing on my last place.

Have a look at what goes across the garage above the current doors. One long wooden beam? Two wooden beams? Lintels? RSJ? Cross section size of the beam/lintel?

I have just done much the same - replaced a 5.1m 100x200 wood beam with a 203x203 UC60 RSJ sitting on padstones and knocked out the central pier/pillar. Steel plus brickwork was £1050 and a Seceuroglide electric roller shutter door with manual override (there's no other access door) was £2150 fitted by PHers Doorman and SupraSi. I did the electrics and new fascia/soffit work myself.

A structural engineer determined the RSJ size - it looks over specified but better that than under specified.

I've just ordered the same size UC to hold up the whole back of a house plus the roof, so yes I'd say that beam is slightly oversized for a garage . I fitted a new garage lintol a few weeks ago as the timber lintol had seen better days, I'm not sure if they do them for double garages but its probably worth asking your local builders merchants, far less hassle than ub/uc.

From what I gathered a lintel in that sort of length (5m+) is very expensive and the steel is cheaper.

Second hand RSJ ? £50. New door ? Feck knows. I wouldn't waste my money.
