I think you would end up with endless complaints from neighbours about noise and cars and people coming and going. You are going to have problems with constant damage to the house...you won't know the people coming - they could turn up in droves with drink and drugs and goodness knows what. like someone else said, it sounds more like a club... you're right, it ain't going to happen !

I reckon without [e.g. removing an upstairs room floor and installing an indoor plunge pool in the ground floor room below it for jumping into, or some other similar kind of] a unique selling point, it will have very little appeal that isn't just putting a price tag on what most people can have for nothing, while those that cannot usually cannot for a reason and those who would see it stays that way will be, for the most part, parents and law enforcement, or anyone who knows where party lifestyles end up dumping people out if they indulge too much.

Essentially it's a 'venue' or 'business premises' - so check into that.

Personally - it would have to be more than a house for ￡3 a head, and a big house at that, a spacious five bedroom may only just ensure your 'admin department' has an on-site office, which may be deemed necessary so any issue can be resolved 'in situ' & 'stat'.

Further to other answers - I'd say it would be physically easier to soundproof than to do many of the other required refurbishments that make it suitable for this purpose.

The main issue is whether to call it a hall/club/entertainment venue/? and declare your interest - it may be something heretofore unallocated a definition and usually because if it isn't 'one of the above' it must therefore be in breach of some vital requirement for running such a business.

- You will have to break the proverbial mould with it.

Sounds like a club. You better check out the zoning and your neighbors about these house parties first they might not like that you have a house being converted into a club.

Maybe you can be an event coordinator to arrange house parties for these people then you can charge them for your equipment and your services.

It might be more legal to lease a building that's light industrial/commercial and just make it look/feel like a 'house party' somehow. Make it BYOB, setup some beer pong tables, sound system, check for student ids at the door..

Not sure you've thought it through...change of use, fire certificate, nuisance....

Probably defo NOT going to happen, but keep having ideas - sooner or later one will be viable.

So house party's seem to be all the rage at the minute so if I was to buy a second house and keep it very basic but kit it out with some stereo speakers all around an then a music source it could be a house purely for house party's- I would charge for you to get in(say ￡3? Or should I charge more) it's not defo gonna happen but it's an Idea and I was wondering people's opinions :) thanks
