    Preliminary pipes for central heating later

    Hi I am getting the keys to 30's semi in need of refurbishment this Friday. We'll have the place for a month before we have to move out of our existing place, so a certain amount can be done. There is no central heating, but we're planning a rear extension and side utility extension, which we...

    Structural ridge: 9" x 2" enough for 13' (4m) span

    In your house the roof is prevented from sagging and spreading the walls by the floor joists acting as rafter ties. I'm going for a self supporting, or structural ridge, which has little deflection and therefore transmits the load born by the stud walls downwards. This is going to allow me...

    Structural ridge: 9" x 2" enough for 13' (4m) span

    Hehe, how do you know what I'll be doing inside the shed once it's built? Seriously though, I think he means to follow Tony's calculations further rather than to build a shed. Since Tony was kind enough to share his knowledge, I thought I would follow it up and learn something...

    Structural ridge: 9" x 2" enough for 13' (4m) span

    Tony, thank you so much for helping out, very grateful. Just for fun and to follow your calculations : I reckon the rough dead weight of the roof to be: Ply (18mm): 110kg Felt + membrane: 25kg Rafters (100mm x 50mm): 42kg But I'm lead to believe the self weight of the rafters can...

    Structural ridge: 9" x 2" enough for 13' (4m) span

    Great, thanks for the info. I will use your calculations as a starting point for more research. Learning! When you say 5 sq m, I calculate my total floor area to be 10 sq m (4 x 2.5) Taking into account the 12 degree pitch and the overhang I'm going for, it seems to me I'll have rafters...

    Structural ridge: 9" x 2" enough for 13' (4m) span

    Jeds, Tony, Very good point! The floor plan of the building will be 8' by 13' (4 x 2.5 m to be precice). The pitch of the roof will be 12 degrees, and there will be 18mm ply on top of 4" x 2" rafters at 24" centres. The roofing material will be breathable membrane and standard felt...

    Structural ridge: 9" x 2" enough for 13' (4m) span

    Hi, Thinking of finishing my garden building with a structural ridge. The span will be 13' (4M), and I have some 9" x 2" stock of sufficient length. I want to avoid rafter ties. The rafters will be 4" x 2" at 24" centres. Is 9" x 2" enough? Should I screw and glue two together giving...

    Felt or shingles

    Hi, Just deciding on felt or felt shinges for a garden building project. Shingles are going to cost at least 5 times as much by the looks, although maybe not in the long term. I really like the look of shingles, and am trying to get away from the 'shed look'. The third option I'm curious...

    Garden building construction

    Hi, I am just finishing the framing on a new garden building project, and wondered what people think of using bolts to secure the corners. The walls are made from 2x4 studs. I"m using a mixture of 4" and 3" screws for the framing and noggins. The plans I'm following don't even call for...

    Ideas for insulation

    No, it's not the neighbours I'm worried about. There is one of those damned paths between our back garden and the rear of our adjoining neighbors. We have had burglaries in the street, including people's summer houses being raided. These paths make the neighbourhood like a rabbit warren for...

    Ideas for insulation

    Yes, I have an ebay search running for surplus/recycled rockwool panels now :) Floor, walls and ceiling will only cost about £200 from new slabs, so there is always that option. No drums or guitar, just a garden office. Perhaps a little bit of radio, tv and telephone activity. Near...

    Ideas for insulation

    Hi, I am looking to insulate floor walls & ceiling of a small garden building. The acoustic properties are more important than the thermal ones. I know that for the best acoustic insulation you need mass and to restrict the air flow. I am obviously looking for the most cost effective...

    Stud wall for outside building

    There would be two joins: Is this arrangement for a top plate considered strong enough when the wall has to bear the weight of the roofing? Thanks.

    Stud wall for outside building

    Hi, What's the best way to make long stud walls? I have a space for a building which I would like to have 4.5 m side walls, and I have a lot of timber to use which is only 3 m long. Is it ill-advised to make a top plate for the stud wall from shorter pieces? I was thinking of a...

    Frankenjoists

    Thanks for the reply. I take your point. I'm just working to a pre-existing plan. Mind you, it will be a workshop, and it will have a drill press, a heavy bench, a lathe, a table saw and lots more in there, so I'd rather be safe than sorry given the abundance of stock I have...
