Rear wc and shower

User4search

Hi guys , i an thinking to have wc and shower at ground floor at rear of house. Drainage pipes are  at rear only just 3-4 feet from the rear wall are private. 

Is it allowed ? Where to start? Do I need to building authority,  council approval?

Technically you might but practically don't worry about getting approval if you are just converting part of your existing house. I used to do a lot of work for a landlord who had a load of rental properties and we used to put extra bathrooms in, change bedrooms to bathrooms and vice versa I extended my own bathroom within the house footprint and no-one gives a hoot.

Draw a plan of what you'd like and get in touch with some plumbers or builders depending on work to be done. If you make contact now you might be able to get one to start in January.

Thanks , to clarify more..  i am interested to build wc in place of tables in attached image which would be considered as an extension I guess . Is it within house footprint?

Extending the house is outside my scope so I'll bow out.

It's not just "drains" you need, but access to the sewerage system. I think my builder said that if you wanted to add another sewage pipe to the manhole, it needed notification and inspection by the water board as well as complying with building regs.

No, it isn't within the house footprint. 

It's disproportionately expensive to build a very small extension.   I'd say that you should be building on the other side in order to get close to be able to connect to the drainage above ground.  (And also because you've got serious window issues if you build where the tables are!) 

I'd speak to an architect as I suspect you would be better to utilise some existing space for your shower room and perhaps build a bigger, more practical space that provides better value for money.

you may not need planning permission if it falls under permitted development, but you will need building control approval, definitely, to inspect the build.

Is it freehold? If it's leasehold you need to look at your lease and probably get permission from the freeholder.

first floor bathroom and toilet drain pipe connects to  ( black vertical pipe) and goes into neighbour boundary land and then comes front of our rear kitchen where tables are located and pass horizontally as shown in above drawing so that is private  sewage pipe and is used by us only and it becomes public/ shared when it crosses the neighbour's boundary at front of house. We have 2 private  inspection champers at corners in our house boundary.

Do you have a floorplan you could share? It's easier to understand in a single glance than reading through the text.

There is so much potential at the rear of the house, don't bother with a small extension - extend properly and do it once. Otherwise you may as well just build an outhouse, it would be cheaper.
