If you think the bay windows or deep window ledges that come with the newer flats and apartments are a waste of space, you can actually make use of them and turn them into something more functional!
Bay windows are often seen as a wasted "feature", and lots of homeowners don't know what to do with it. However there are ways to utilise this deep ledge or window seat to suit a variety of purposes.
Build on top of it to create additional usable surfaces, such as a desk or vanity. For a built-in desk, customise the table such that it extends outwards beyond the edge of the bay window to ensure enough legroom while you sit at the desk.
