I have to admit I haven't given it much thought, but it's a good point!

It depends if it matters to you. 1cm gap under your door is practically unnoticeable but that's up to you. Vinyl boards/tiles are very thin so your builder is right that there will be a gap. The only alternatives are: using laminate instead of LVT, building up floor thickness with plywood, adding a door seal under the door

Hi Victoria. I hope I’m not having a moment but the Isla has removable covers so presumably dependant on fabric choice is washable rather than dry clean?! https://www.sofa.com/gb/sofas/corner-arrangement/isla-corner-sofa/p/CS-ISL

They’re not misleading building estimates but an estimate is just that … an estimate not a firm quotation. Being in the construction industry myself we too have problems getting customers to realise just how fast materials and prices are increasing. We now only offer a 14 day validity so we can TRY and purchase at the same cost that we have allowed for in our customer’s quote. We have even been quoted a price in the morning and then when we have gone to buy the items in the afternoon they've gone up again. Perhaps you can get the shell done and then do the finishing touches when funds have been replenished. These are very difficult times for customers and traders.
