Winter Gardens should form a complete whole with the house, they should not be in a different style. Realization is usually additional, only a few years after the completion of the house. Most people lack such a place in the house, or they did not have enough finances in the house building.
The best situation is of course if the realization of the Winter garden is already part of the original project and construction of the house. Then it is the best design of the house as a harmonious whole. But this ideal situation rarely happens.
If the realization of the Winter garden is done retrospectively, it also brings a number of problems. Sometimes it is not easy to follow exactly the regulations and instructions provided by the manufacturer. For example, the minimum suitable roof slope and other elements.
