Hi, i have recently purchased a plot with a atcost barn on it passed for a dwelling, it is permitted development type planning.

The structure is a concrete portal frame, the structural engineer is struggling to work out what load it will take as it is concrete and he doesnt know what re bar was used etc. On the planning it is passed for pan tiles which is obviously heavier than the asbestos roof so there will be extra load on it.

We have contacted atcost but because they where taken over they are not sure whether they have got the information.

Because it is permitted development we have to leave the structure up.

Can any one help on where to find information or anyone that has done similar and what they did.

Many thanks.

Shawn
