When it comes to construction and remodelling, straight lines are a fairly typical and expected style. It makes sense since we can more easily forecast the structural load and estimate production costs when shapes are made of straight lines.
I think it’s uncommon for someone to think about using curved lines in a building while designing a remodel or new construction. Curved buildings will probably be more difficult to construct and require more materials and labour. Therefore, even if the concept could appear good, it is quickly abandoned when you, the Client, find out how much it might cost to construct an “outside the box” design.
