If you want to have a room you can use all year round you will need an effective mechanism for heating and cooling the space – especially for north- and east-facing conservatories. To keep the space ventilated you must have roof vents. For shade, blinds are available in a range of materials and styles. Thomas Sanderson specialises in high-tech awnings that have built-in heaters and lights. Its Monaco Patio awning is remote control operated with an infra-red heater that gives instant warmth to the area under the awning. Prices from £2,500.
