The Atrium 3 boasts a southern corner
sunroom. Two walls of the house face south.
Both the southeast and southwest sides receive sun. The central atrium brings light down into the
middle of the house so that the kitchen and central study are also bathed in
southern light.
First Floor
French doors can close
off the sunroom for acoustical privacy and for days when the sunroom may have a
greater temperature swing than the rest of the home. The center hearth in the
living room can house a wood stove or fireplace which can be two-sided and
shared by the sunroom.
Morning sun will
stream into the master bedroom in winter.
In summer it will receive some rays through the northeast window which
also helps with passive ventilation. The laundry is conveniently located near
the master bedroom and it has a door to the outside for quickly hanging out
clothes.
A variety of outdoor spaces
extend the first floor living spaces. The spacious northwest front porch has
room for rockers and swings to watch the evening summer sun. The screened porch
is open on three sides for maximizing breezes that cool outdoor dining. The
southern deck is a great place to catch some winter rays on non-windy winter
days. The narrow walkway connecting the deck and back porch maximizes sun in
the lower level.
Daylight Basement
The sunny stairs
lead to the lower floor with 3 bedrooms, a study, exercise space, TV area and
mechanical rooms. This spacious level almost doubles the home’s living
area. Since so many of the walls are
earth-bermed, the rooms will require less additional heating and cooling energy
to stay warm in winter and cool in summer than if they were on the second floor
or a two-story home. With the numerous
windows and walkout patio, it will be hard to tell that the rooms are below
grade.
Garage Option
The detached
garage can house two cars with a workshop or greenhouse space, or it can be
modified for three vehicles. It can
easily be attached to the house via the laundry or through the screened porch
based on home owner preference.
Construction Info
First floor ceilings
are vaulted which adds space and character. Basement ceilings are 9’ tall. Stud walls and rafters are easily adapted to
insulation requirements of various climates by varying the amount of exterior
insulation. Thermal mass is in both the tile floors throughout the home and in
the brick or stone wall in the sunroom.
Solar panels can be placed facing southeast and/or southwest on the
roofs, or on ground-mounted poles.
Modification Ideas
Since these ideas
may affect energy performance and structural integrity, they should only be
undertaken with professional assistance.
- Build on a concrete
slab for a small, high mass one-story home
- Let the sunroom
be a bedroom by converting the hearth space into a closet and rearranging the
master bath to add a door
- Reverse the
home to place the garage on the northwest
- Slide the
screened porch to the southeast in front of the living room or sunroom to give
the dining room southwest views
