A large glassed-in terrace was built adjacent to the user’s house. Two walls are glassed in. One glass wall has sliding doors that the user can open and close by himself (see associated tip). Along the entire longer wall is a ramp leading to the garden. Infrared heating was installed for chilly days. The terrace is not insulated, but is still essentially frost-free.
The user selected a dining table for the terrace that is the right height for him and has knee space on the short end (see Photo below).
When the user bought the house it only had a small terrace. The user enlarged it and had it glassed in. It became a large indoor space where he can sit and enjoy the outdoors.
