At this remove, other than offer generalisations, we can't help. I'd plan on removing the tank and replacing it with a treatment plant. Either now or at some point in the future . DIY about £6k, otherwise £10k. Choose the system with the least moving parts. That type uses an air blower(s).

You don't. They do.

I don't know the answer to the question. But here's what one of our most respected contributors had to say about retaining walls - he had to solve the same problem as yours..... From a very simplistic (and therefore possibly wrong) point of view - if anyone digs in such a way as to possibly compromise the safety of a property that already exists, then it is the responsibility of any builder to preserve what already exists. '...looks like ... isn't '...is...' until you obtain a qualified opinion. We (Buildhub contributors) are neither qualified, nor expert - nor local to you. Please ask for a properly qualified Structural Engineer's report.

Here Be Dragons (potentially). I sincerely hope my warning is unnecessary. The subject of SoftAndSmellyStuff in conjunction with joint ownership or responsibility has always been tricky for us. And in this case the tank is not on your land. A lot needs to be unraveled here. And that may in part explain the lack of interest by the companies you have contacted. Their approach to you might be more positive if you were able to say to them....Put this particular tank in that particular place and connect up the piping.

Exactly

In haste: Forget the past Find another suitable patch to bury your own treatment plant Read the General Binding Rules Follow them to the letter Identify somewhere safe to discharge the treated liquor (General Binding Rules) Buy a digester Bury it : foul drainage and power as well (SWA electric cable only) Connect it all up Test it AND ONLY THEN Disconnect the other Flushed with your own success, sit and smile.

Welcome to the Worriers Club. Just occasionally I manage to enjoy the process of worrying. But it is now normalised : and thus less of a worry. (? !) Its par for the course. Every day. But it keeps me sharp. It makes me think. It makes me research. A lot. It keeps me engaged. It keeps me a little bit uncomfortable. And - if you let it - discomfort teaches. Hence BuildHub. Hence shared hardship and shared privilege. Signed, Old and Disgraceful of Lancaster

Welcome! Thanks. If you have time, tell us the main lesson you've learned while extending your bungalow.....

We have some really narrow windows. Craig at Gaulhofer worried more about those than the larger windows.... those 'slit' windows look narrower than ours.

I think you may have to import them. I very much hope I'm wrong. The Berlin part of my family is coming over here soon (in a VW van) . Want some ? If you want to do your own research they are called ' Dachtritte ' (in Germany) I think many of them have a mechanism for changing the angle of the tread ( because of the change of angle on many roofs.) Here's a relevant (German) website and these cost just over 100 euros - But I'm almost sure it will be cheaper easier and quicker to make your own - if you are that way inclined.

Easy @joe90. Just been to Berlin - family stuff, and asked that very question .... The steps are put in for Chimney Sweeps. Notice each of the images above lead to the chimney. So I asked the obvious question - and was told that a chimney swept from below and from above was '...much cleaner...' And then asked the next obvious question - which was met with a shrug. The other reason for the steps (or sometimes built in hooks) was for areas which have high snowfall - and thus steep roof pitches. The hooks are also lined up across the roof such that the gap can be bridged by scaffold board held in place on ladders which have small platforms on them. And of course Health and Safety - my raised eyebrows were answered by " Well would you want your chimney sweep dad to work on a dangerously steep roof?" As a small aside, Chimney Sweeps have to (by law) sign off every woodburner stove in Berlin. They sign off to say that the wood burner stove is working efficiently. And thus have a nice-little-side-hustle. Einfach!

@Pocster - get the Dodgers out. I mean he's even mown the grass within a few mm of its life. There's nowt there that a bit of expanding foam won't cure.

Let's keep it simple. Don't consider buying that building without a full, expensive survey. None of us, at this remove can offer anything more than generalisation or Cautionary Tales. I offer the '... usual advice...' therefore. Because that's all we can do.

Welcome. Please excuse the cheeky question - you do have Planning Permission don't you.... for a Listed building? You're a magician if you have. Go to the top of the class. @Pocster will award you a jammy dodger in due course.

Top Banana. It takes '....built in.... to a new level (see what I did there ?) Angle grinder will sort that problem out ... easy.😑

I had a neighbour who did a lot of climbing up here in the Lake District. Several of his climbs in Sadgill and the South Lakes had (have?) Peregrines nesting there. He told me - straight-faced - that the only part of a pigeon that Peregrines don't eat is the ring on its foot. Hence the little piles of rings near the nest. I told him - equally straight faced - to weigh the rings in. And then we went for a pint.

Yes. They can be remarkably stupid. Put some food down (where rats can't get at it) and put some old ply down behind the food (overshoot protection) . If you want, paint the wood white - easier to tell where the sight reticle is pointing. This is the time of year when Rattus Norvegicus starts to think about keeping warm on your dollar. Consider smearing peanut butter on the ground (makes the rat sit still for a second or two) and the pigeons will have a go at that too. Suggest heart and lungs shot for pigeons - head for rats. No more than 20 meters range. One of our two youngest tomcats is brilliant at keeping them down; 't other sleeps most of every day.

No. Just put it up.

Thats what's so much good fun about joinery : its about how to deal with stuff thats somehow got out of line. Straight lines, straight cuts are easy. Our tame chippy says that dealing with bent houses - and there are loads hereabouts is the core of his job.

Generalisations are sometimes dangerous. Ours didn't Here's the detail

Yes, Chat GPT will soon be able to do so. Its great to be in at the beginning of yet another revolution. The more we use it responsibly and with care and discretion, the better it will get.

Harrrrumph.... mine was a 1985 vintage. Leaked water out almost as fast as it leaked in..... Sold it to pay for concrete wasted in the bursts on our ICF adventure. I'm gonna cry now .... cry myself to sleep. No - thanks , I'm OK, don't worry.

Yep.... Brush cutters are grand. Mine is about 12 years old now, doesn't work that well though. Tends to be quite difficult to start, and often needs to stop for extended breaks - to make adjustments to the cutting edge equipment. His earbuds that is. He's a good lad really. 12 years old - going on 45 and about 6 foot 3 already. He only needs cups of tea, bad grandad jokes and £10 notes. Wha's not ter like?

@Sren, could I politely point out that we are not Planning Experts ( @IanR appears to be as close to one as it gets - but there's the exception that proves the rule) . We are merely interested, helpful - and nosey - amateurs. Experts by Experience as the research literature calls it. There is no substitute for obtaining proper professional advice. Good luck! Ian

Welcome. I see you have found the delight and strength there is to be found in reading BuildHub. ... my calculations [ ... ] based [...] on information [...] put together from looking on this forum... They say that T'internet is the place for shared ignorance. That doesn't last long here: and for good measure we usually add TakingThePiss to our online offering. Have you thought of asking a company to specify and quote ? I have a feeling you might have - but just in case... Welcome anyway Ian
