The shape being decided, its time for what I believe is the most important part of any design, the proportions. That is the factor that makes the difference between good and bad, practical and unpractical.
As in the roof angle debate, also here I’m interested in the visible mass. The higher the building, the more it will stick out.
Another consideration is the amount of outside wall relative to the plan. I have a limited surface area to use and the house is located within the national park with no visible neighbours so I want to maximise the visibility from inside with large windows. And the narrower the plan, the more windows I get.
Yet another favourable factor for the long and narrow shape is that different functions can be placed further apart. A typical house has public and more private functions. Living room and kitchen being at the public-end and bedrooms and bathrooms at the private-end. Ideally these functions should be as far apart as possible. And with the long shape that’s achievable.
- The lower the less visible mass
- Long and narrow looks interesting. These proportions are typical for transporting a lot of people but not that typical within a house
- Narrow plan offers more wall/window space
- Public and private functions can be separated
