Surveyor recommendation needed, structural pointers + Harringay ladder, through reception room, double doors required

Hi there, 

I was wondering if anyone could recommend a good surveyor who is familiar with the Harringay ladder houses. We require one, for a full survey, on a Seymour Rd house that we are hopefully buying : ) Also is the any particular points that we should be looking out for on this type of property please?

Also, if all goes through (touch wood), we were thinking of putting the partition wall and double doors back up between the two reception rooms. Does anyone have these doors to sell or know where you can buy them from?

Many thanks, 

Matt
