Two story home designs remain the most popular style. One question to consider is do you want a home design with a large entrance foyer open to the second floor or convert that space to additional finished area?
While the grand foyers make for an impressive first impression, seems like there has been somewhat of a trend towards space oriented value by closing the foyer to maximize the useable square footage in the cost to build.
A compromise may be a home design like the “Stanford” where there is a partial open foyer which visually gives a volume feel as you enter and provides for natural light but does not reduce the square footage appreciably.
