Replacing garage roof from flat to trussed.

We don’t want to lose the double garage under any circumstances. 

You wouldn't have to, You would need a Steel beam to support the wall though.

On this house it looks a bit daft to me, so i was mostly joking anyway, I would stick with the Shed or doing it correctly at full height and length.

:-) I did wonder. That pic was more like "You are looking for ideas for an extension? Take your pick from this house."

I totally get TE's wish to use this space, tho' - it would surely be cheaper than a new extension or separate outside room (unless a cheap pre-fab 'garden room' type), wouldn't eat up any plot space, and - more importantly - should hugely improve the appearance of the garage and house frontage?

I am sure there are benefits of the pic you have posted, however, just to be clear for any future contributors, it’s not remotely what we are looking for.

We want to explore changing flat garage roof to a traditional roof in order to create a small studio in the roof space. The existing internal measurements of the garage are 5m x 4.8m which should give us something in and around 3.05 x 4.46m which is perfect.

You have hit the nail on the head. We were genuinely hoping for some discussion around changing the flat roof to a traditional roof. Not full extensions, garden rooms, losing the garage etc. 

Perhaps with hindsight I didn’t make that clear.

I do fear the cost could end up far more than any added value here, especially if corners are cut.


In the second photo you posted the wall is raised up a foot or 2, Would the current beam take that or would it need replacing anyway?  How will you get in, Stairs from below that will take a lot of room? Or if a door from the house will you end up with the headroom for a door?

It is more complicated than just changing it to a standard roof, Maybe loft conversion companies would be the best place to get quotes from.

You could start with getting a quote for the attic trusses from here  https://www.tailormade-frames.co.uk/attic-trusses

No intention of cutting corner - apologies if I have given this impression.

Regarding the beam - that question will have to be investigated by a professional. Access will be from a stair in the garage - no access is needed from the house, the space will be used as a private studio area accessed only from the garage.

Thanks for the link.

It surely cannot be a 'big' job? It's just timberwork, surely?!

It depends whether the walls and foundations have the loadbearing capacity for the additional loads.

It could be a 'demolish everything and dig new foundations' job.

Using the a number of £2k per sq meter i come up with around £26K, That could be a totally the wrong number for a 'loft conversion' £19.5K could be closer, Building from the ground up from footers are usually quoted as costing 3K per sq meter.

I'd expect the optimum solution would involve one or two steel beams across the width of the garage to reduce the effective span of the trusses/cut roof.  That's one reason why the existing loadbearing capacity of the walls will be an important factor - the loads from these beams will need to be taken down into adequate foundations.

Although you plan on keeping the garage studio separate from the rest of the house, I personally would try to aim to have the finished floor level of the studio the same as FFL of the first-floor of the house (if practical).  That way if you change your mind in the future it would be possible to knock through, without having to worry about dealing with different floor levels. You may never want to do that yourself, but the next people might, and being able to tell them you've had the alterations designed to allow that possibility may help you sell for a better price.

I like this suggestion a lot. Whilst it’s not what we need now it would potentially be a good selling point of the future.
