Colors used to depict the space are very dark and bland. I think a different choice of color would have made a big difference.
The choice of furniture was poor in my opinion, and made the space look quite gloomy and uninviting.
The idea to put the dining table next to the pergola is a very good one, I like the idea of having the table there.
The arm chair where the dining table used to be is out of place. Whoever sits there will be facing the back of the heater, so not the best use of space.
Overall there was nothing striking about this design, although some of the layout like the dining room were good ideas.
