Unfortunately,the conveyancing solicitor's arm,will have the same,slight curve in it,and will direct the OP in a giant circle...
There are loads of estates,going back to new-builds in the 90's,one right near me,where the properties are legendary,for missing insulation,due to gangs of brickies,dragging the same four pieces of full-fill,up the cavity...look like a tiger's head,on the FLIR.
New builds,in this country,are more in need of a thorough survey,than a 200 year old cottage,but various schemes,obviate that....and it's a shame ?
A quick trawl,on the internet,will show the magnitude and nature,of some of these developments...it also shows up the level of help available,and likelyhood of a satisfactory conclusion.
Having seen footings poured on tipped ground,piles a shovels depth,and whole properties with missing insulation,cavity closers and wall-ties....there is nothing left,on a brand-new,executive development,which would surprise me
