laurenco Posted October 23, 2018 Share Posted October 23, 2018 So here's something we found in the ground when levelling our site ... an old swimming pool. I said "under the house" in the title, but it's only under the ground surface level by inches and therefore a basement leisure area is not an option. As it falls half under and half outside our new house's footprint we have a problem. What do we do with it? Remove it all and pay for the concrete to be taken away say. 4 loaders + 1 or 2 days labour Put a metal deck on top and moth ball it. c. £2k materials + 2 days labour. Expensive and doesn't achieve a great deal Fill it in with hardcore and pretend it's not there. Cheap; we have loads of hardcore. Raft foundations will go on top. But will this be safe? We could create a 3m x 2m x 1.25m high wine cellar beneath the kitchen, but I'm trying to guestimate costs and I think it will be thousands of pounds. The glass hatch alone is £2k and that's assuming MBC can work their foundations around this. Has anyone experienced anything like this before? and / or, can anyone offer any other solutions? (nice answers only please ?) Link to comment Share on other sites More sharing options...

Think the total size is 2600x900x1400 and I expect the door will cost about £60 and the steps will be from scrap 8x2.... 1 Link to comment Share on other sites More sharing options...
Nickfromwales Posted October 23, 2018 Share Posted October 23, 2018 I doubt I could ever build a house without a basement tbh, as it’s such a waste of useful space. Even more so if this was my forever home. 1 Link to comment Share on other sites More sharing options...

I see the benefit if you are tight on space or can only go single storey but otherwise if you can get the size you need anyway I don’t see the point of one TBH.

It’s quite obscene the amount of wasted space a residential dwelling can create. A basement adds, up to, an entire floor so why would you not? You’ve paid top dollar for your plot, you need foundations, so just make them very long, deep foundations and bingo. Get a trap door for the 4 kids and “sorted!”. 1 Link to comment Share on other sites More sharing options...
PeterW Posted October 23, 2018 Share Posted October 23, 2018 Nothing .... there is 100mm of PIR over the top but nothing more Ground is sand around here - very dusty in the bottom of the pit and no real sign of damp. Temperature has stayed a static 9-10c which is ideal for wine ..! 1 Link to comment Share on other sites More sharing options...

Ok, so good for imprisoning children, or to use as a dungeon or torture chamber then. You’re not selling it TBH. My take is that I deffo wouldn’t want a larger house and would much rather have something with natural light. Horses for courses I guess ?.

Declan52 Posted October 23, 2018 Share Posted October 23, 2018 I would be using it for a home cinema type setup. Would be perfect. Or how about having it as a swimming pool. How does your house sit on it. Could you move it slightly too try and incorporate it?? Link to comment Share on other sites More sharing options...
laurenco Posted October 23, 2018 Author Share Posted October 23, 2018 @declan52 unfortunately we don't have the height. With a roof on it, it'd be 1.25m high at best inside. Moving the house forwards on the plot to miss it would take the house too close to the road. Moving the house backwards 3 metres to cover it completely might work, but without the head height it's largely useless. I think we need to abandon it completely and fill it in.

Declan52 Posted October 23, 2018 Share Posted October 23, 2018 Would be a lovely feature in a living room, definitely eye catching!!! Just seems such a waste to fill it in. Some sort of wine cellar, pantry would be handy. On your current plans as they are where would the access point be. Link to comment Share on other sites More sharing options...
AliG Posted October 24, 2018 Share Posted October 24, 2018 If you want to use it as a basement you shouldn't need to tank it as it is a swimming pool so should be water proof. You could insulate the interior, it wouldn't need much as it is underground, but putting some kind of roof on the part outside the foundations would not be easy. It would probably have to be at least 200mm thick so would either reduce head height or stick out above ground level. Plus it would need to support whatever landscaping you wanted to have. Are your foundations not dug down a few hundred mils into the ground? If so they will go right through the middle of it reducing head height to well below 1m. You will also have to knock out the sides where the foundations sit. I would think just filling it in with hardcore to give a good base for the foundation is the best solution. Even if the foundations could sit on top I would still probably do this. A SE would probably want to look at it. A pool should have plenty of load bearing capacity, but I would think they want it confirmed. 1 Link to comment Share on other sites More sharing options...

A basement is right for some, but here, with our very high water table, the cost of adding a basement in £/square metre would be more than just building a bigger house, and we have enough land that if we had wanted a bigger house we could do so.

scottishjohn Posted November 13, 2018 Share Posted November 13, 2018 my first guess would be it was filled because it leaked,so assuming it would be tanked is dangerous Me I would knock out the walls of it and hardcore it as any other foundation and carry on mybe you can get concrete crusher on site cheaper and you use it as hard core? or just disc cut the walls and use them as hard core in bit bits on the pool floor 1 Link to comment Share on other sites More sharing options...
laurenco Posted November 13, 2018 Author Share Posted November 13, 2018 I suspect you're right @scottishjohn about it leaking and then being filled in. I've had a quote to disc cut the top of the walls and lay them on the pool floor which sounds like the cheapest way forward. I'm waiting to hear back from MBC on whether we can sink a sewer pipe in the 'deep end' and access it through the floor of the house without ruining our insulated foundations.

scottishjohn Posted November 13, 2018 Share Posted November 13, 2018 you really want a sewer manhole in house ? what if sealing is not good? --and sealed ones will be expensive -surely better a bit more plumbing +bends if required and have it outside that would be my first choice?

The idea, I think, is to tank it and use it as a wine cellar, as in the photo. I can't see any obvious reason why setting some rings in the deep end of the old pool, tanking the outside of them, with a basement membrane underneath and running up the outside to above DPM level, shouldn't work just fine. There will be a bit of heat loss via the hatch, but that could be mitigated with a better insulated access hatch design. 1 Link to comment Share on other sites More sharing options...

joe90 Posted November 13, 2018 Share Posted November 13, 2018 If you fill it in, it will save you a fortune in skips ? we had to dispose of 150 tons of clay.£££££££. Our current problem in our new build is Storing veg somewhere cool (we drink the wine too fast to store it!). 1 Link to comment Share on other sites More sharing options...

(nice answers only please ?) Have you worked out the Muckaway savings if you fill it in? At (guestimating - not my thing but @recoveringacademic will have it in SPONS) say £5-10 per cube to have it taken away filling that pool in with your scrapings could save ~£1500 (at say a conservative 1-1.5m by 6m x 12m = 70 cube to 100 cube), which at the least would pay partly towards your bridge over the top if you need one.
