Lots of our customers chose to have an extension with bi folding doors so they can extend their living area to outside!
Depends on the house. An extension with bi fold doors and lantern to the flat roof, appears the way forward. For many houses this is the correct decision, providing a large light filled room.
But a conservatory gives the ability to sit in the garden. To hear the rain. A room not filled with light but to sit in the light. Modern glass roofs and windows are so different to the early conservatories. We use ours 12 months a year. It can also be used to bring heat back into a house.
A conservatory, even to modern standards, is so much cheaper than an extension. So small extension or large conservatory? Large conservatory every time.
