We are potentially in position B and are trying to weigh up the pitfalls of proceeding. This has emerged very late in the day and it should have been disclosed much earlier. Essentially our proposed 4 b/r house should be a 3 b/r with a loft space. I know there are other threads on this issue. I've read them all and Googled the life out of the problem. It divides into 'it'll be fiiiiiiinnnnee' (as per our estate agent) or 'run a mile'.
I've just disclosed it to an insurer that had quoted for our proposed purchase and the customer service agent sought advice from the underwriter. His reply was 'decline quote'.
If you are in A) and have sold a house in similar circumstances (which happens every day and nobody's bovvered according to the agent), how did the agent market the property. Was the irregular loft included in the b/r count? Or did they err on the side of caution and keep it as a useful space, games room, casual living facility. Basically can the estate agent be found wanting here or is this par for the course.
We will have lost a couple of thousand in survey and solicitor fees so I will be complaining bitterly if they have misrepresented this property. I would follow up with the property ombudsman if I was sure of my ground. It helps therefore if you have experience of the approach of your agents.
It does look as if there was a certificate of lawful development in 2012 so this loft has been around a while without the house falling down. So far as I can see this doesn't get round the building regs issue. The vendors already have indemnity insurance that predates their purchase which is why I am certain this was a known issue. I can see that the insurance was issued to their solicitor so they must have known of the defect from the outset.
Over to you Mumsnet. I appreciate the help.
