Thanks for the reply,and the welcome! I’ve had a bit of a look about in terms of rafter spans and looks like I will likely require 5x2 going off the span chart I came across,this isn’t something I know about just going off a span chart I saw online The proposed garage goes over the drainage run and is located close to manhole also,It’s a combined rainwater/sewer system so I will be addressing the underground pipe anyway so will just be adding an additional gulley for downpipe

So I’m in the planning stages of a couple of extensions to my property,first of which is adding a garage onto the side of the house (currently have a detached single garage in back garden which I will be demolishing) As title I’m looking to do this under permitted development which I’m assured is doable by a local plans guy I’m hoping to tackle a lot of the work myself,subbing out the blockwork I’d just like some input on the simplest/basic way to carry out a garage build,It will be a lean to in effect so I’m thinking/hoping: 450mm footings if I can get away with them Single 6” solid block construction Pitched roof using wallplate/rafter construction with 4x2 timber Does this sound feasible? I don’t need anything fancy ie habitable so no insulation and there won’t be an intergral door into house just a front 2.2/2.4 garage door and a rear upvc door to garden If anyone has done similar and can give me a rough idea of project costs too that would be great!
