Is this an answer on what cost I should add to it? Or is this related to what the council charged you?We gave a 50% on the additional work fee.
Not creating an open plan. The hallway with the staircase in it will see 2 changes to it, but it won't be opened up in any way:Are you changing (replacing) the stairs or repositioning it The main issues would be if you were creating an open plan so that you create an inner room where previously there was none or if there is already an open plan area, opening up the kitchen into this area increases the risk of a fire to the access room.
- A small area will be boxed off with a stud wall to create a downstairs toilet, intention is to use 50mm by 75mm timbers with 9 - 12mm plasterboard to not loose too much space
- I intend to remove the staircase and put a new one in to the same opening, but turning it 90 degrees. Plan is to get this made and then just fit it.
