There is no honest ranked list here yet. A useful comparison needs current, like-for-like specifications from manufacturers, and the verified dataset is still being built.
The criteria
Models will be compared on stated cladding profile and finished thickness, framing detail, floor and roof construction, glazing, treatment, warranty terms, supplied base requirements and installation information.
Missing information will stay visible. A model will not receive an invented score to fill a gap.
What “best” will mean
Each future category will state the use and deciding criteria in its heading. A good-value seasonal reading room is not the same choice as a larger building intended for frequent shoulder-season use.
