"Log" Garage, double door

[Skyedriver]

Looking for suggestions,
I'm looking at a 5.4m x 5.4m "log" garage (the type here the logs interlock at the corners)

The one I'm interested in only has a single width door but I want to modify it to fit a double width up and over or roller door, say 4.8m wide.

The manufacturer says "a 4.8m opening wouldn’t really work as would be too wide a span for logs to remain straight above opening ie they would bow."

I'm wondering about a steel frame or timber frame reinforcement around the opening. Maybe something like 50mm x 225mm timber up the sides and over the top, screwed or coach bolted to secure the log ends. Even inside and out to sandwich the logs if necessary.

Any thoughts or better options?

The only wooden ones I have seen double have 2 sets of doors, assuming this is no good to you either?

I have a single-size one behind the house, which is my man cave. The front-to-back spars are about 6" deep and 16ft long. They're not supported from front to back, they span the whole depth of the cabin, and over the years they have sagged a little - not enough to be a problem, but it would be if they were over a door, so you'll definitely need something. Mine's been up about 6 or 7 years now.

I purchased one of those exact garages for my previous home. Tons of room for two cars side by side but the door set up precluded that use. I widened the frontage of the opening and then simply widened the timber doors. Simple.

Get 2 or 3 sheets of OSB or ply. Cut one to fit the centre apex area. Cut the others to sandwich on the centre board to the outside walls.

Fairly cheap and simple to do and just screw them onto the front on the inside.

Perhaps fit a 'goalpost' type steel frame to the inside of the double door aperture, and fit eh roller door to that,

Steels can be ordered, welded with fixing plates & drilled etc for a few hundred £££.

They'll come in red oxide so budget for paint to suit.

IMO..

Thanks but slightly too wide and they don't deliver to our area on the west coast of Scotland
I think that one will be over the 30 sq m floor area so will require the relevant Building Warrant/Planning etc

Thanks for that, any pics?
Do you now get two cars in?
Did you just widen the existing timber doors?
Did that not strain the hinges? That's why I'm thinking of an up and over or roller door.

The manufacturers suggested steel frame also. Will investigate

Not sure if I have pictures I will look today.
Since moved house but two cars in the garage was easy when doors widened.
Yes I widened the existing doors, easy job use same timber available most places. Strengthen the diagonal braces behind door following same pattern.
No strain on hinges but you could add extra hinge, I didn’t worry and it was fine.
Easy job and save a packet of cash.

Edit to add :IIRC about 35cm off each door but have a measure up.

Slight side issue but we previously had a garage of a similar style (they are not all the same in design nor word)). It used to massively expand and contract at different times of the year and we had quite a few issues with window and door alignment so maybe watch for that and consider it across the wider span even if using an rsj or similar to bridge it.

Yes you can buy these garages with the thinner wood, we went for the heavy wood and had no problems over the ten years use before we moved. I used to use a coloured preservative every other year as maintenance, but that was really belt and braces.

do https://www.tuin.co.uk/ have any that suit, I recommend the company, delivery and customer service.

4.8m is a fair span, assume it will need to take the weight of the roller shutter. You may get away with a SHS which would be neater, but it's probably cheaper just to go with an 'I' beam. The goalpost frame arrangement is the way to go mate - a local Structural Engineer will knock a design for that up in about 15 mins.

Roller shutters are largely self-supporting, remember, with most systems. The point loads at either end can be taken down through posts.

I had the single skin one of these, around 32 foot long, used it as a snooker room/gym. The insulated ones may be better but I'll never buy one of these again - total rubbish. The walls move a lot, gaps appear, windows/doors go out of alignment, roof twists.

One other minor point if you have a motorbike, insurance often (bikesure don't) won't class it as a garage if it is made of wood, they'll class it as a shed, even with roller doors.

sadly no, I know about the quality of Tuin but there isn't one of the right size and w are outside of their normal delivery area.

Or you could always chop down some oaks and build your own like me
