A cantilevered bay window is a way to blend your indoor and outdoor areas as well as adding space. This design also includes storage under the seat, making for a functional reading nook. Here, architect Brian O’Tuama offers us tips on building your own version.

• Consult a structural engineer on the suitability of your chosen wall. If you’re working at ground level and the walls are strong enough, no foundations are necessary.
• If your home is listed or in a conservation area, planning permission may be required. Check first with your local authority.
• Choose which areas to glaze, and be aware that the more glass you use, the more expensive the project will be. Sometimes the main face and one side-pane can be enough to direct the view towards the most picturesque part of your garden.
• Include storage by creating pull-out drawers under the seat, for easy access. Radiators can also be recessed below the banquette, as long as you install a grille to allow air to circulate.
