I am planning to build 3.6x6x2.5m SIP board garden office on top of the concrete slab floor without foundation wall and feeting. Concrete slab floor will placed on top of the insulation. Can anyone recomend me the best underslab insulation material/product with high compressive strength and U-value take on heavy weight of whole garden office without foundation wall.

Hi all, I'm considering buying a house with a large (5x5m) conservatory. The grand plan would be to convert the conservatory into a 'proper' extension - brick walls, tiled roof etc. I've read people on this forum saying "yes, if the foundations are adequate, check this by digging a pilot hole". My qu is - if the foundations are inadequate, can they be 'upgraded'? Is there much saving in converting a conservatory vs just building an extension from scratch? I'm looking to get a very rough feel for how much it would cost to convert a conservatory of this size to a 'proper extension'. Does not involve kitchen or bathroom work. Many thanks in advance.

Do I require a trade person to fit a dog flap into a double glazed patio door

What are the benefits and disadvantages of project managing a house extension? How can I tell whether I should do this or leave it to a professional? Does it depend on the type of extension that’s planned?

I am renovating a small 2 bed terrace house. There are numerous repairs required. These include roof and chimney repairs (stripping slates adding weather barrier and refitting), ground floor repair / renovation and damp tanking (floor joists rotted at front wall), kitchen door move (to existing window) / wall alteration (RSJ) and new fit units, bathroom new fit, new windows / doors (6 windows, front and rear door, 1 small velux), possible rewiring, yard wall demolition and rebuild, free standing garage demolition and removal. I am currently looking for quotes for works required. How much generally should I expect to pay? High and low estimate?? Cheers

We would like to brick up our kitchen doorway and replace (and enlarge) a window opening, fitting small bi-folding doors (around 70'inch opening) on the same wall. Any ideas how much this might cost (minus the glazing)? Thanks.

How can I tell if a wall is load bearing? I know that seeing 'if it sounds hollow' isn't necessarily enough!

Could you please advise me as to what product could be used to bung up the hole/s, in the cement, under the fascia, of my roof? Which would set hard, and be rat-proof. Rats have climbed up the drain pipe, to crawl into the hole, and entered the roof space. I need to deal with the problem quickly. Would I need scaffolding, as opposed to a ladder? It is in an awkward place. I have posted a job, but no one has got back to me, so I am considering doing it myself. Is there any kind of guard, that could be put around the drainpipe? To stop the rat/s from climbing up it.

How can you prepare the ground before having a carport fitted? If I do it myself will it mean less of a charge if hiring a contractor to install the actual carport? Or does it depend? What do you think should be the case usually? Thanks.

How long does concrete floor screed take to fully dry? Can I speed the process up at all?
