a sampling of Sigi's projects
Every Project Integrates:
(as appropriate)
Passive solar design for free winter heat & summer coolness
Natural daylighting ensures excellent quality light inside
Rubble trench foundations with lower cost & less disturbance
Super insulating strawbale walls for low energy consumption
Natural clay plasters inside, harvest from the building site
Lime plaster or durable siding outside for weather resistance
Living roofs that keep out the heat of summer sun
Renewable energy options dovetailed into the design
Natural, sustainable, & healthy building materials
Below is a sampling of buildings designed by Sigi...all natural, all with standard permit approval.
Serge & Joan's Home
strawbale home in Meyersville MD
This passive solar home features hand-crafted details throughout. Strawbale walls keep heat inside in winter, while a curvaceous living roof keeps the space cool in summer. Other features include cob walls, adobe floors, thick clay plasters, & site-harvested wood throughout.
Broomgrass Home
strawbale home in Gerrardstown, WV
Natural building meets modern architecture. This strawbale home marries ancient materials with high tech systems and an updated look. The focus was to bring in ample sunlight, connect to the outdoors from every space, & ensure superb energy efficiency. The result is a quiet, elegant oasis.
Mike & Esther's Strawbale Addition
strawbale addition outside Washington, DC
This was my first strawbale project, designed with Helicon Works. The strawbale addition features many salvage materials. And generated almost zero waste during construction. We even reused the clay soil dug out for the foundation to build 2 cob mass walls inside.
Adams Morgan Remodel
green remodel in Washington, DC
The challenge with this historic DC townhouse was to open the maze of living spaces. We stripped everything to the bones & saved all of the unique wood work for reuse. We also added a sliding glass wall to bring in more light. The end result is open and airy with spaces that flow with life.
Alexander Feldman Home
strawbale home in Shepherdstown, WV
This strawbale home is designed for a budding family. Passive solar strategies ensure the home is flooded with free solar heat in winter, while staying shaded & cool in summer. Backup heat is provided by a wood-fired masonry heater. A graywater system plus composting toilets handle waste naturally.
Zinnes Folly
garden studio in Bethlehem, PA
I built this little garden folly for my Mom. Almost all of the construction took place during 5 weekend workshops. The structure rests on a rubble trench footer and is constructed using salvage & natural materials. Above is a luscious living roof to accent the garden it sits in.
Iris Youst Home
strawbale home in Keene, NH
This home is a great reminder that strawbale walls can be finished with siding (instead of the typical lime plaster). The super-insulated house stays toasty through the coldest winters with passive solar strategies...plus a little help from a wood-fired water heater that warms all the floors.
DeGraf Home
strawbale home near Harpers Ferry, WV
This passive solar strawbale home was built almost entirely by the owners…who had little construction experience. This empowerment is precisely the beauty of natural building! The home uses strawbale & cordwood insulation, cob mass walls, and a super-efficient masonry heater.
Zigbone Farm Retreat
naturally built retreat center in Sabillasville, MD
Zigbone Farm is a unique place with a unique vision…to transform old farm buildings into a comfy country getaway. The existing buildings all received energy efficiency upgrades. While new construction features strawbale walls and a variety of natural finishes.
Black Ankle Vineyard
strawbale winery in Mt. Airy, MD
Black Ankle is truly dedicated to natural building. They've built 4 super-insulating strawbale buildings to date, with more on the drawing board. Finishes feature site-harvested wood, clay plasters inside, lime plasters outside, plus planted roofs for passive cooling.
Lotus Cottage
strawbale studio in Capon Bridge, WV
Yes…strawbale buildings can be curvy! This cozy studio keeps passive solar principles in mind with 3 huge salvage windows that allow free solar heat in winter, while blocking hot summer sun. Clay is used extensively for floors, walls, & plasters. Built over a summer by the owners & many volunteers.
Long Home
strawbale home in Bucks County, PA
A new natural home designed to look timeless. Adobe with in-floor heating provides comfortable radiant warmth all winter, while strawbales with thick natural plasters ensure the heat stays inside. In summer, the same materials, keep the inside nice and cool…naturally.
Judd Home
strawbale home in Frederick, MD
This round home still follows passive solar principles despite all the curves. It was built by the owners with strawbales insulation plus clay floors & plasters. They incorporated a plethora of salvaged building materials & site-harvested wood to keep costs down and quality high.
Studio Apartment
strawbale tiny home in Arlington, VA
Yes, you can build tiny with natural materials! This studio apartment sits on an existing garage founation. The strawbale walls insulate so well that a tiny space-heater keeps the whole place warm. The lofted bedroom is accessed by a space-saving alternating ladder stair.
Bach Addition / Remodel
green renovation & addition in Madison, WI
The goal of this addition was to add a master bedroom suite & art studio, plus improve the flow of living spaces. But the true mission was to reuse everything and incorporate tons of reclaimed materials. Everything found a re-purpose! We even snuck in a secret room...
