What type of window do I need?

Hello forum,


I would like to have a small porch built as we're expecting our first child in Decemeber, so will need a place to store necassary things. However, every quote so far has been pretty high for what I consider a fairly small job, between 4.5k to 7k for a dwarf wall 3sqm job.



With that in mind, I was planning on buying the bulk of the porch as a sort of 'kit'. My main issue is that I cannot find the name for something I need. It is so my window can look like it has been extended seemlessly.


Unfortunately it won't let me add pictures to this post, so that kind of makes things hard to work out.. but it is a square bay window, 1930's style. The entire top floor and bottom floor window extend out.


Thanks in advance.
