Soil Stack / Extension Question

Hi all - just after some quick advice - sure its simple.

We're thinking about an extension to our house to add ensuite.

Current soil stack is opposite side of the house, around 7m away on the opposite flank wall, although the kitchen sink is located on the middle of the rear wall.

W're thinking of adding an ensuite on the opposite side of the house (opposite flank wall to soil stack). This would be part of an extension across the whole of the back of the house.

Am I correct in thinking that we could (as part of the groundwork for the extnension), we could put in a new soil stack and then an underground gulley along the back of the house to the drain?

Just guaging viability before getting someone round to draw some plans up.

Thanks.

Groundworkers usually lay the drainage as part of their works. Provided you can get a suitable fall on the pipe runs, and manholes are fitted at any changes in direction there's no reason why you cant.

Under no circumstances fit a macerator.

Depending on the size of the extension & location you'd need Planning permission & a building warrant. Employing the services of a good Architect is a must, he'll draw up plans for approval & include the drainage alteration/extension.

My advice is to employ a small firm of Architects or a one-man-band, but ensure they keep their artistic licence in check when spending YOUR money. Don't let them run away with 'tree hugging' ideas about saving the planet!!

Be careful if you employ the services of a Main Contractor/ Builder & ensure you have a Small Works contract in place or you'll get shafted.

Thanks for the replies - will be getting an architect and explaining our requirements vs budget clearly!

Who will save the planet if not the people who live on it?
