Situated in the heart of Charlotte, this contemporary home is part of the ReAlta neighborhood. ReAlta is the first solar community in Charlotte, NC.
The ReFresh plan boasts an expansive rooftop deck, a private master suite at the back of the home, a light and airy front office and more windows than we can count.
What the homeowners love:
Huge energy savings from the solar & energy saving build process
Super quiet interior rooms (from the insulated interior walls)
Large windows placed for optimal sunlight and privacy from the neighbors
Smart home system that's part of the house
Low, low utility bills (resulting from the solar and the home's thermal envelope)
ReFresh is a 3 bed, 2.5 bath home and is 2,450 square feet.
With ReAlta, we are introducing for the first time in Charlotte a fully solar community.
Each beautifully detailed home will incorporate low profile solar panels that will collect the sun’s rays to significantly offset the home’s energy usage. Combined with our industry-leading Home Efficiency Ratings (HERS), these solar systems will save a ReAlta homeowner thousands over the life of the home.

An extra large second floor patio is perfect for outdoor entertaining. It’s the perfect vantage point to look out over the neighborhood, but its second story location also provides more privacy than a typical front porch.

The owners of this 1960s ranch house loved their house but it wasn't configured to meet their needs. The house had only two small bedrooms for the family of four, and there was no casual living space for parents and kids to hang out separately. Neither we nor the clients wanted to increase the home's energy usage. It was a tall order: could we increase the home's size without increasing its energy footprint?
ADDING FUNCTIONALITY
We built two small additions, one at the front of the home and one off the side adjacent to the two existing bedrooms. These new spaces provided an additional bedroom on the main level as well as a new stair down to the basement. At basement level, the additions yielded a guest room, a full bathroom and a laundry area. The existing basement, which is now easily accessible from the main floor, was refinished as a casual family room.
The architect designed the new spaces to be spare and bright, replicating the mid-century aesthetic. Every detail—from the open stair, to the light maple floors, to the detailing of the bathroom vanity—echoes the vintage and character of the original home.
INTEGRATING ENERGY AND DESIGN
The key to meeting this challenge was a rigorous and integrated planning process with early-stage energy modeling accompanying design. As the architect (Anita Rogers) worked out the space plan, the energy consultant (Mike Duclos) analyzed how various scenarios could be combined with envelope and mechanical packages to not only hold the line on energy use but improve performance. We anticipate the plan we settled on will save 25% annually over pre-project energy use.

The design objective was to build a house for a couple recently married who both had kids from previous marriages. How to bridge two families together?
The design looks forward in terms of how people live today. The home is an experiment in transparency and solid form; removing borders and edges from outside to inside the house, and to really depict “flowing and endless space”. The house floor plan is derived by pushing and pulling the house’s form to maximize the backyard and minimize the public front yard while welcoming the sun in key rooms by rotating the house 45-degrees to true north. The angular form of the house is a result of the family’s program, the zoning rules, the lot’s attributes, and the sun’s path. We wanted to construct a house that is smart and efficient in terms of construction and energy, both in terms of the building and the user. We could tell a story of how the house is built in terms of the constructability, structure and enclosure, with a nod to Japanese wood construction in the method in which the siding is installed and the exposed interior beams are placed in the double height space. We engineered the house to be smart which not only looks modern but acts modern; every aspect of user control is simplified to a digital touch button, whether lights, shades, blinds, HVAC, communication, audio, video, or security. We developed a planning module based on a 6-foot square room size and a 6-foot wide connector called an interstitial space for hallways, bathrooms, stairs and mechanical, which keeps the rooms pure and uncluttered. The house is 6,200 SF of livable space, plus garage and basement gallery for a total of 9,200 SF. A large formal foyer celebrates the entry and opens up to the living, dining, kitchen and family rooms all focused on the rear garden. The east side of the second floor is the Master wing and a center bridge connects it to the kid’s wing on the west. Second floor terraces and sunscreens provide views and shade in this suburban setting. The playful mathematical grid of the house in the x, y and z axis also extends into the layout of the trees and hard-scapes, all centered on a suburban one-acre lot.
Many green attributes were designed into the home; Ipe wood sunscreens and window shades block out unwanted solar gain in summer, but allow winter sun in. Patio door and operable windows provide ample opportunity for natural ventilation throughout the open floor plan. Minimal windows on east and west sides to reduce heat loss in winter and unwanted gains in summer. Open floor plan and large window expanse reduces lighting demands and maximizes available daylight. Skylights provide natural light to the basement rooms. Durable, low-maintenance exterior materials include stone, ipe wood siding and decking, and concrete roof pavers. Design is based on a 2' planning grid to minimize construction waste. Basement foundation walls and slab are highly insulated. FSC-certified walnut wood flooring was used. Light colored concrete roof pavers to reduce cooling loads by as much as 15%. 2x6 framing allows for more insulation and energy savings. Super efficient windows have low-E argon gas filled units, and thermally insulated aluminum frames. Permeable brick and stone pavers reduce the site’s storm-water runoff. Countertops use recycled composite materials. Energy-Star rated furnaces and smart thermostats are located throughout the house to minimize duct runs and avoid energy loss. Energy-Star rated boiler that heats up both radiant floors and domestic hot water. Low-flow toilets and plumbing fixtures are used to conserve water usage. No VOC finish options and direct venting fireplaces maintain a high interior air quality. Smart home system controls lighting, HVAC, and shades to better manage energy use. Plumbing runs through interior walls reducing possibilities of heat loss and freezing problems. A large food pantry was placed next to kitchen to reduce trips to the grocery store. Home office reduces need for automobile transit and associated CO2 footprint. Plan allows for aging in place, with guest suite than can become the master suite, with no need to move as family members mature.

The modern floating vanity is oversized with two sinks and ample counter space. The shower is the focal point of the room featuring two shower heads each with customized temperature settings. The light and airy feel of the home continues with a skylight above that floods the space with natural light.

This 12-light chandelier incorporates a piece of living edge Eucalyptus and recycled glass tequila bottles for an extraordinary piece in a contemporary lake house.

The battery back-up system supplies power to all the household appliances and lights in the house and will keep them working for four hours during load shedding power outages. This system fits neatly under the staircase.
The Italian Piazetta wood oven supplies heat through tubes to the main bedroom, patio, study and needlework rooms while the rest of the home is heated with a heat pump that takes approximately 30% less electricity than the average electrical geyser.
A gas geyser was installed to supply the kitchen with warm water and to avoid wastage of using long pipes throughout the house.
All outdoor windows and sliding doors where fitted with double glazing. This retains heat that saves energy and lowers the noise levels in the home.
LED lights were fitted throughout the house to reduce the electricity usage to less than 10% than conventional light bulbs.

Along the teak-paneled kitchen wall, sliding and pocketing doors open to reveal additional work and storage space, a coffee station and wine bar. Architecture and interior design by Pierre Hoppenot, Studio PHH Architects.
