Having an extension to open across the back of a 30s semi, creating a room which will have the kitchen, dining table, and a sofa/coffee table area overlooking the garden. Big picture windows and lantern skylight so it shouldn't be too dark. I like the idea of having one or both side walls with exposed bricks. In my head this will be fabulous industrial chic. But will it actually be dark and grotty? Has anyone got this? Do you love it or regret it? Help me decide!
