We are having a loft conversion done on our top floor flat. 5 weeks ago I approached the freeholder for the flat next door, he told me it was fine in principle, he just needed a week to think about it. I hoped at that point it wouldn't be necessary to appoint a surveyor. I gave him the architect's plans. 2 weeks later he still hadn't decided. When I contacted him next he was on holiday for 2 weeks. This week he's unavailable, etc etc.
Meanwhile the builders had to down tools for a week while we appointed a surveyor as requested by the freeholder on the other side, he has surveyed both sides. Basically this freeholder needs to sign a document saying he accepts our surveyor's report and does not object to the extension. Only he's never in or fobs us off.
Can his not signing jeopardise the project? Could it be an issue when we come to sell? Thanks for any info, we are getting stressed about it.
