[...] 11 Expenses. (1) Except as provided under this section expenses of work under this Act shall be defrayed by the building owner. (2) Any dispute as to responsibility for expenses shall be settled as provided in section 10. [...] (11) Where use is subsequently made by the adjoining owner of work carried out solely at the expense of the building owner the adjoining owner shall pay a due proportion of the expenses incurred by the building owner in carrying out that work; and for this purpose he shall be taken to have incurred expenses calculated by reference to what the cost of the work would be if it were carried out at the time when that subsequent use is made."
"That the Adjoining Owner is entitled in principle to payment under section 11(11) in relation to the proposed underpinning. Reason: It is considered that the works previously carried out by the Adjoining Owner are being used by the building owner."
"The Building Owner shall pay the Adjoining Owner one-third of the costs claimed in respect of Nithya Murthy's fees, namely£1,218.33 ."
"The Appellant submits that the Act does indeed impose a duty on the part of the surveyors to authorise an alternative scheme which avoids unnecessary inconvenience, certainly if they are aware of such an alternative scheme and/or if such a scheme has actually been suggested by the adjoining owner or his surveyor."
"In as much as a building owner is not entitled to exercise any right given him by the Act in such manner as to cause unnecessary inconvenience to the adjoining owner, the tribunal must, in determining the proper way of making good the defect, if there be one, have due regard to the convenience of the adjoining owner."
"Those surveyors are in a quasi-judicial position with statutory powers and responsibilities."
"A building owner shall not exercise any right conferred on him by this Act in such a manner or at such time as to cause unnecessary inconvenience to any adjoining owner or to any adjoining occupier."
"The appointed surveyor should seek to identify and represent the interests of the appointing owner, but this should not extend to following instructions from their appointing owner where these conflict with their duties under the Act."
