I have been working on a wall in my kitchen that surrounds a window. The window sits on a single skin wall. To the right it then meets a solid wall from the original house. To the left it meets the outer wall of a properly constructed cavity wall. I have been building the inner leaf so it is a full cavity wall that meets the solid wall. I have used remedial wall ties between the outer wall and the inner wall but I forgot to use 'wall starters' to tie the new wall into the solid wall and pre-existing cavity wall. I am wondering if this will be a problem. The wall is only 90cm high (where it meets the window) and 180cm long and it meets pre constructed walls on either side. If it is a problem, do I have any alternatives to taking blocks out, putting the ties in and then replacing the blocks? Any advice would be much appreciated.
