CIL question (help)

I have a question from an agent on an application coming in:

The owner wants to put two houses within their garden and the existing house will remain. The main house is for themselves and the second house if for their son.

However, costs are a major issue to make this project viable, now under Band B, the cost per m2 would be £184 per m2.

The house that the owner is building for themselves is 280m2 and the second house is 226m2. Currently that would attract a CIL cost of £93,104!! Now that obviously is a high costs to pay as the reason for the housing is to accommodate themselves and a sibling.

Would both the houses come under Self Build, as effectively the family are building it for themselves, to house themselves and the houses are not going to make profit, can you please confirm and I am sure that this will raise a series of conversations, we also have an AIR BNB on the site which will be demolished, so I am assuming that I can omit this 95m2 from the overall figure?

Hi Jo. I would say that in order to get SB relief, both the parents and the son should apply for relief for their respective plots, bringing the CIL charge to zero. Note the parents as LP for plot 1 (the larger plot) and the son as the LP for plot 2 (the smaller plot). So you would need two sets of forms 1, 2 & 7(part1) and also, eventually form 7 (part 2). You would only need one commencement notice, as this is only one planning permission. The existing site demolition (so long as it qualifies as existing use) should be apportioned according to the site size (280/506 = 55% x 95 = 53 sqm and 226/506 = 45% x 95 = 42 sqm).
