I queried the apparent concrete steps, mentioned by Ottavio Pedretti (Letters, October 5) when visiting the model of the proposed King Alfred development at Jubilee Library and was informed this was merely the architect's way of indicating the contour of the beach, which would be left as it is.

Presumably Brighton and Hove City Council, as freeholder of the land, will only lease the areas containing the foundations of the buildings, excluding the sports centre which is the sprat to catch the mackerel.

On the same letters page, Colin Beard seeks an explanation as to how Karis can make a profit from the venture. Understandably, one will not be forthcoming as the finance of these matters is extremely complicated.

For instance, the leaflet tells us the affordable homes are to be developed and managed by Southern Housing Group, so it would seem these are to be separate from the Karis buildings.
