The Brighton summerhouse is one of A&J’s original buildings and still very popular today.
Available in a large selection of sizes, but with the minimum width being 12′ so that the doors & window fit.

This flat version features a large 12 pane window with a central top opening, positioned to the side of glazed double doors. There is an opening window on each side wall.

An alternative would be the Brighton Bow, which has a curved bow window as supposed to this flat version.
