I'm tapping out these words on my laptop while sitting on my
front porch and watching the world go by. I love our front
porch; time spent hanging out here is a mini-vacation from the
stresses and worries of life — not to mention a
welcome break from the damn telephone.
But not all front porches work as well as they could. I'm
lucky to live in an older neighborhood full of wonderful front
porches, but many new houses have porches that seem to have
been built purely for their marketing value. As long as the
real estate agent or sales department can point out that the
house has a porch, the reasoning seems to go, it doesn't much
matter whether the porch is a living, functioning part of the
house or just a useless ornament (see Figure 1). Here are some
important points to keep in mind when building or remodeling a

occupant convenience and comfort in mind (left). The tacked-on,
inappropriately dimensioned version at right, on the other
hand, is less a true porch than an oversized covered
Depth and Height
A good front porch should be at least 8 feet deep. A porch
much narrower than that can't support a decent "sitting circle"
— the loose ring of chairs that allows friends and
family to face each other while talking. Conversely, a porch
more than 12 feet deep or so is too spacious to provide the
sense of intimacy that a porch should and places the windows
too far into the shade.
Ideally, the porch floor should be between 24 inches and 36
inches above grade. The lower end of this range places the eye
level of someone sitting on the porch higher than the eye level
of someone walking by on the sidewalk, putting the sitter in a
position of strength and safety (Figure 2).
Figure 2.Placing a porch floor between 24 and 36
inches above grade raises the eye level of someone sitting on
the porch above that of people passing by. That allows for some
conversation between porch and sidewalk but puts the sitter in
a comfortable, secure position.
This gives someone sitting on the porch the power to decide
whether to greet or ignore someone passing by on the sidewalk.
To be lower than someone walking by on the sidewalk is to feel
exposed, vulnerable, and unsafe. On the other hand, a porch
that's too high provides too much separation between those on
the porch and those passing below and makes desired
A good front porch should be on the same level as the main
floor of the house (Figure 3).
Figure 3.A porch that's isolated from the house
will get less use than it otherwise might. Plan the grade so
there's no need for more than one very low step —
ideally, no more than an inch or two — between the
porch floor and the indoor living space.
A step from porch to front door that is higher than the 1 1/2
inches or so necessary for the storm door to clear a welcome
mat will isolate the front porch from the rest of the house.
The more the front porch feels like an extension of the main
house, the more likely it is to be used.
Steps and Railings
Steep, narrow steps isolate the front porch from the outdoors.
Wide, shallow ones — say from a minimum of 6 feet wide
to the width of the entire house, with risers no higher than 6
inches — invite the outdoors in. Wide, shallow steps
are also a great place to set potted plants, take family
photos, and relax from mowing the lawn when you don't feel like
stepping all the way up to the porch itself.
The position of the steps is another important consideration.
If possible, a porch should be entered at its edge, not near
the middle. Centered front steps look wonderful from the street
and play to many designers' love of symmetry, but they
invariably cut the sitting area into two disconnected sections
(Figure 4). Steps near an edge, on the other hand, allow for a
big, welcoming sitting circle in the center of the porch.
Figure 4.Stairs that are centered on the main
entrance tend to split the porch in half, making it seem
smaller and making conversation awkward for more than a very
small group (top). Moving the stairs to the side makes the
space much more comfortable and inviting (bottom).
Enclosing a porch with a light, airy railing, rather than a
solid parapet, offers a better view of the outside world,
especially if the railing is low enough to see over easily
A standard 36-inch guardrail, required by
code under some conditions, will obstruct the sight line of
someone sitting on the porch, making it difficult or impossible
to see what's happening at ground level.
But things can get tricky when the local code requires a
guardrail: The standard 36-inch guardrail will obstruct the
view of someone lounging in a wicker chair, and standard 2x2
balusters at 4 inches on-center are difficult to see through.
(The new International Residential Code requires a code
guardrail only when the porch is 30 inches or more above
One possible solution is to push the guardrail down to 30
inches and run a continuous handrail at the required 36-inch
level. Another is to use inconspicuous cable rails, if
stylistically appropriate. If no guardrail is required,
consider building a flat-surfaced railing at a height of 24
inches — just the right level to sit on or set down a
glass of iced tea.
Orientation and Exposure
A front porch should be oriented to the street and human
activity. Most Americans are inherently social creatures. We
love to know what the neighbors are up to, who's walking by on
the sidewalk, who's dating the younger Olson girl. Unlike
private indoor living areas, a good front porch should be seen
as a semi-public room that allows for some give and take with
the outside world. It can't fulfill that purpose unless it's
open and visible.
To retain the feel of an open outdoor room, a porch should be
exposed on three sides. A two-sided porch that's tucked into a
corner of the house seldom works well. It feels enclosed,
making it too much like the inside of the house. And from a
purely practical standpoint, it doesn't enjoy the total airflow
of a porch that's open on three sides (Figure 6).
Figure 6.A built-in porch with only two exposed
sides feels more like a room than a true porch. Because seating
tends to be concentrated against the house walls, those sitting
there miss out on the cooling effect of the evening
For the same reason, porches should be open to the elements
or, at most, screened to keep out mosquitoes. In theory, a
storm-window-enclosed "three-season porch" can be used earlier
in spring and later into autumn, but the reality is that adding
any glass — no matter how much or how wide the windows
open — is the kiss of death. The wonderful feeling of
sitting outside is lost, and in the summer, when the porch
should be most heavily used, the glass traps heat and makes it
unbearably hot. The sad reality is that most three-season
porches just get used for storage.
