This is kind of Home Cinema / DIY related so I think it's appropriate for this forum. I'm currently having a single room extension built onto the back of my house that will be my new cinema room. I have an ongoing article for the new room available here: http://www.dvdlard.co.uk/content.php?id=1385 My problem is the extension goes across the back of the kitchen and covers the kitchen external window. Originally I just bricked up the window and thought I'd rely on the new French Doors in the kitchen to provide sufficient light. Unfortunately this hasn't worked out well and I need to get some more natural light in the kitchen. My father (who's also my builder ) says to just put a window back where it's bricked up, but I find the idea of a window between two rooms within a house a little strange. I'm just wondering if anyone has any alternative ideas. some ideas discussed so far are: Glass blocks (other half not too keen) Open hole (perhaps with shelving) In-Wall Fish tank with both sides showing (again other half not too keen) Whatever I do I have to make sure that I can block out the light when necessary in the cinema room. Any suggestions guys?
