I'm nearing the stage in my loft conversion where I need to fit insulation, I've got a huge stack of 70mm thick Celotex, I need 2 layers of this across the entire roof space. The first layer is straight forwards to fix, just screw through into the rafters, but I'm unsure what to do with the...

No pets, it would have to be incontinent to cover the whole garden anyway! (the bad bit is about 100m2)

Back in spring I completely stripped my garden (full of weeds, stones, glass and generally not very flat!), spread about 8 tons of topsoil and reseeded it. Half the garden now has a lovely thick lawn, but the other half is patchy, yellowing and full of weeds. The two parts of the garden were...

I'm just prepping to fit a Velux window in my loft (GPL S06 with an EDP plain tile flashing kit), and I'm trying to work out what the relevance of the 105mm dimension on this step is about... Unfortunately, because this window is such a tight fit, I can only move it by up to 50mm, so that...

I would imagine that doubling up between the purlins would increase the load on the purlins, ideally I'd double up the entire length so the load is transferred to the wall plate and ridge. Saying that I'd be suprised if it would be a problem (the purlins are a reasonable size at 3" x 7" for a...

Posted this in 'Floors, Stairs and Lofts' but this is probably a more suitable forum.... I'm planning on installing a couple of roof windows in my loft, since I'm cutting 2 rafters I'll need to double up the side ones, however there's a couple of purlins that prevent me from getting full...

I'm planning on installing a couple of roof windows in my loft, since I'm cutting 2 rafters I'll need to double up the side ones, however there's a couple of purlins that prevent me from getting full length rafters in. How would one go about doubling these up? The only way I can think of is to...

Invaluable as always Freddie :) reckon I'll go with 50mm studs, it's a pretty small wall anyway (2.0 x 2.0m triangle to box in the stairs). Anyone any idea on the total door width? Might just go out and buy a frame if not...

Evening! I'm just working out a few details for a loft conversion, and I'm having trouble finding door frame dimensions. Could anyone tell me what the total width of a door frame will be for a 27" 30 min fire door? I've come across conflicting information, but it appears a standard door frame...

I disagree that they should be detailing everything, for example the joists hangers have been specified as 'jiffy/speedy hangers, of suitable size, grade and fixing to support 2kN sustained load'. They could have said 'use joist hangers model xxx nailed with xx twist nails xxmm long, fixed to...

The structural engineer actually specified the jiffy hanger method, I was just considering other options, I wouldn't expect a structural engineer to go into every detail and dimension anyway. This is the kind of question that a builder would be more qualified to answer, since they've actually...

Do you use face fix or jiffy/speedy hangers? Thanks for the tip, it's one of those things that's probably really obvious once you've finished the job :p

I'm currently planning out a loft conversion, and I'm after some advice on how best to support the joists. My structural engineer has spec'd 152 x 152 x 30 UC beams for the floor, one of which runs through the middle of the room, these support 47 x 147 (regularised 50 x 150) joists, my problem...

I've just had some calculations through from a structural engineer for steels for a loft conversion, which says that no padstones are required assuming the existing bricks have a minimum compressive strength of 20MPa (N/mm^2). The bricks are standard solid red bricks, house built around 1930...

The purlin extends about an inch outside the building, so at least the load is across the full width of the wall. Been thinking today, would it be better to get it bricked up? I'm having 3 Velux windows (2x 114mm x 118mm and 1 x 78mm x 118mm) installed, so there shouldn't be a lack of light, I'm...

I'm currently in the process of redoing a dodgy loft conversion, this morning I've been removing the old plaster from the walls, I've discovered that the window in the gable wall has no lintel, I'm no builder but this seems absolutely nuts. To make it worse, there's a purlin resting right above...

Why's that? Wouldn't work here cos I have about 40m of privet and 2m of holly, that'd be a mighty gap in the hedge...

I currently have about 40m of privet surrounding my house, about 2m of that has been taken over by holly, how should I go about removing it? I don't mind having a gap for a year or 2 (there's already another gap), if I can successfully grow another privet in it's place. I think it's slowly...

Not in a conservation area and definitely not an area of outstanding beauty :P If the underlay isn't a building regs requirements I'll probably add it after completing the loft, but keep it a high priority. Thanks again for you're advice, I'd be lost without it!

I've just had an architect round to get a quote on doing some loft conversion plans, I was slightly puzzled when he told me I need to apply for planning permission because I want to put a velux window on a roof slope that faces the road (house is on a corner, both slopes are visible from the...
