As we change the footprint of our 1920s cottage, we are trying hard to ensure that the new blends in with the old. Much of the cottage is original - including the single glazed lead windows. We were hoping to use the original windows in the kitchen and just relocate them in the extension. Sadly, building regulations said no. So two solid, and original, Arts and Crafts windows have had to be removed (we have vague plans for them) and replaced with double glazed units. It made me a little cross. We could have opted for PVC, but the new extension would have stuck out like a sore thumb. So, Mr M has found a local carpenter to recreate the windows as close to the originals as he can. And we've decided to use the original wrought iron catches and bits and bobs on them, so that they blend in internally. Silly perhaps, but for us it just feels right as we slowly renovate.
