Rooms such as the living room and dining room often have the best views.
Rather than obstruct that with a porch, why not place the outdoor space to the side, as shown in the floor plan above, along an otherwise viewless hallway or kitchen?
It may take a little creative thinking to make the roof scapes work, but hey, that's why there are architects.
The Payoff:
How much more you should expect to spend to pay for an architect to put your porch in the right place: 15% (compared with slapping it on your house's front).
