Party Wall enclosure costs for basements - What you need to know

Monday 4th February 2019

Tayross Associates recently worked on a job in inner London where we were asked to calculate the enclosure cost for an existing retaining party wall originally built by the Adjoining Owner.

We were successful in convincing the adjoining owner's surveyor that the cost should only be calculated at the time of the construction of the basement; as we have discovered from previous experience that the wall in question cannot always be used as there is often problems with over-sailing concrete which needs to be cut away; normally using diamond drill equipment which can prove to be very expensive and we normally advise that this is offset against any enclosure cost at the time of calculation .

Some surveyors will insist that enclosure costs be agreed and paid for before work start on site. This puts the Building Owner at a distinct disadvantage as if they discover any over sailing concrete that requires expensive correction then they have to pursue the Adjoining Owner for the extra cost having just paid for the right to enclose upon this wall which can be very difficult to do.
