There are a lot of terms that we have to describe various kinds of exterior domestic spaces. As "outdoor living" is becoming increasing popular in Colorado if not around the county, I find that my clients are often using different terms for same space. Is that place where the picnic table is going to go the terrace or the patio? Is it a deck or a balcony? So, with some images of projects I have designed, here goes:
patio: attached or detached, hard-paved, on the ground and of the earth
terrace: attached or detached, hard-paved, most importantly, it is raised from the earth around it, but not yet a deck.
veranda: attached to the house, roofed porch
porch: attached to the house, covered or open, can be enclosed
To be frank I am not really sure what is the difference between a porch and a veranda. Maybe porch implies entry in a way a veranda does not. A veranda sounds more expensive.
balcony: attached to the house, covered or open (juliette balcony: not projecting)
deck: attached or detached, wood construction and elevated above the site
