Garage glow up

[Lukas239]

Looking to make the most out of a newly purchased single garage and the first thing I wanted to do was insulate & board the loft, hoping to make use of the space for storage.

Looking at roof webbing, I suspect the trusses(?) are not load-bearing and ill need to add some supports. What is best way to do this? Not looking to put much up there but would like to be able to stand on the boarding when done. Attached longitudinal view of the timbers below.

I bought a Barratts house with a sizeable double garage.
Those trusses look the same as mine and the site manager told me I should use that roof space rather than the roof in the house so ok to board it.

Glow up.

Looks a similar construction to mine. How much are you planning to store? I've not really got weighty things up there because of carrying up and down.

Looks like my garage too. I floored it with chipboard flooring panels and keep quite a lot of stuff there, though nothing very heavy. That was 20+ years ago and no problems.

I supported the structure a little by bolting a short chunk of horizontal timber onto the breezeblock column on each side so that the horizontal section sits on it. That way it can't sag.
