The program consists of a detached Guest House with full Kitchen, Living and Dining amenities, Carport and Office Building with attached Main house and Master Bedroom wing. The arrangement of buildings was dictated by the numerous majestic oaks and organized as a procession of spaces leading from the Entry arbor up to the front door. Large covered terraces and arbors were used to extend the interior living spaces out onto the site.
All the buildings are clad in Texas limestone with accent bands of Leuders limestone to mimic the local limestone cliffs in the area. Steel was used on the arbors and fences and left to rust. Vertical grain Douglas fir was used on the interior while flagstone and stained concrete floors were used throughout. The flagstone floors extend from the exterior entry arbors into the interior of the Main Living space and out onto the Main house terraces.

Lincoln Farmhouse
LEED-H Platinum, Net-Positive Energy
OVERVIEW. This LEED Platinum certified modern farmhouse ties into the cultural landscape of Lincoln, Massachusetts - a town known for its rich history, farming traditions, conservation efforts, and visionary architecture. The goal was to design and build a new single family home on 1.8 acres that respects the neighborhood’s agrarian roots, produces more energy than it consumes, and provides the family with flexible spaces to live-play-work-entertain. The resulting 2,800 SF home is proof that families do not need to compromise on style, space or comfort in a highly energy-efficient and healthy home.
CONNECTION TO NATURE. The attached garage is ubiquitous in new construction in New England’s cold climate. This home’s barn-inspired garage is intentionally detached from the main dwelling. A covered walkway connects the two structures, creating an intentional connection with the outdoors between auto and home.
FUNCTIONAL FLEXIBILITY. With a modest footprint, each space must serve a specific use, but also be flexible for atypical scenarios. The Mudroom serves everyday use for the couple and their children, but is also easy to tidy up to receive guests, eliminating the need for two entries found in most homes. A workspace is conveniently located off the mudroom; it looks out on to the back yard to supervise the children and can be closed off with a sliding door when not in use. The Away Room opens up to the Living Room for everyday use; it can be closed off with its oversized pocket door for secondary use as a guest bedroom with en suite bath.
NET POSITIVE ENERGY. The all-electric home consumes 70% less energy than a code-built house, and with measured energy data produces 48% more energy annually than it consumes, making it a 'net positive' home. Thick walls and roofs lack thermal bridging, windows are high performance, triple-glazed, and a continuous air barrier yields minimal leakage (0.27ACH50) making the home among the tightest in the US. Systems include an air source heat pump, an energy recovery ventilator, and a 13.1kW photovoltaic system to offset consumption and support future electric cars.
ACTUAL PERFORMANCE. -6.3 kBtu/sf/yr Energy Use Intensity (Actual monitored project data reported for the firm’s 2016 AIA 2030 Commitment. Average single family home is 52.0 kBtu/sf/yr.)
o 10,900 kwh total consumption (8.5 kbtu/ft2 EUI)
o 16,200 kwh total production
o 5,300 kwh net surplus, equivalent to 15,000-25,000 electric car miles per year. 48% net positive.
WATER EFFICIENCY. Plumbing fixtures and water closets consume a mere 60% of the federal standard, while high efficiency appliances such as the dishwasher and clothes washer also reduce consumption rates.
FOOD PRODUCTION. After clearing all invasive species, apple, pear, peach and cherry trees were planted. Future plans include blueberry, raspberry and strawberry bushes, along with raised beds for vegetable gardening. The house also offers a below ground root cellar, built outside the home's thermal envelope, to gain the passive benefit of long term energy-free food storage.
RESILIENCY. The home's ability to weather unforeseen challenges is predictable - it will fare well. The super-insulated envelope means during a winter storm with power outage, heat loss will be slow - taking days to drop to 60 degrees even with no heat source. During normal conditions, reduced energy consumption plus energy production means shelter from the burden of utility costs. Surplus production can power electric cars & appliances. The home exceeds snow & wind structural requirements, plus far surpasses standard construction for long term durability planning.

This modern green home offers both a vacation destination on Cape Cod near local family members and an opportunity for rental income.
FAMILY ROOTS. A West Coast couple living in the San Francisco Bay Area sought a permanent East Coast vacation home near family members living on Cape Cod. As academic professionals focused on sustainability, they sought a green, energy efficient home that was well-aligned with their values. With no green homes available for sale on Cape Cod, they decided to purchase land near their family and build their own.
SLOPED SITE. Comprised of a 3/4 acre lot nestled in the pines, the steeply sloping terrain called for a plan that embraced and took advantage of the slope. Of equal priority was optimizing solar exposure, preserving privacy from abutters, and creating outdoor living space. The design accomplished these goals with a simple, rectilinear form, offering living space on the both entry and lower/basement levels. The stepped foundation allows for a walk-out basement level with light-filled living space on the down-hill side of the home. The traditional basement on the eastern, up-hill side houses mechanical equipment and a home gym. The house welcomes natural light throughout, captures views of the forest, and delivers entertainment space that connects indoor living space to outdoor deck and dining patio.
MODERN VISION. The clean building form and uncomplicated finishes pay homage to the modern architectural legacy on the outer Cape. Durable and economical fiber cement panels, fixed with aluminum channels, clad the primary form. Cedar clapboards provide a visual accent at the south-facing living room, which extends a single roof plane to cover the entry porch.
SMART USE OF SPACE. On the entry level, the “L”-shaped living, dining, and kitchen space connects to the exterior living, dining, and grilling spaces to effectively double the home’s summertime entertainment area. Placed at the western end of the entry level (where it can retain privacy but still claim expansive downhill views) is the master suite with a built-in study. The lower level has two guest bedrooms, a second full bathroom, and laundry. The flexibility of the space—crucial in a house with a modest footprint—emerges in one of the guest bedrooms, which doubles as home office by opening the barn-style double doors to connect it to the bright, airy open stair leading up to the entry level. Thoughtful design, generous ceiling heights and large windows transform the modest 1,100 sf* footprint into a well-lit, spacious home. *(total finished space is 1800 sf)
RENTAL INCOME. The property works for its owners by netting rental income when the owners are home in San Francisco. The house especially caters to vacationers bound for nearby Mayo Beach and includes an outdoor shower adjacent to the lower level entry door. In contrast to the bare bones cottages that are typically available on the Cape, this home offers prospective tenants a modern aesthetic, paired with luxurious and green features. Durable finishes inside and out will ensure longevity with the heavier use that comes with a rental property.
COMFORT YEAR-ROUND. The home is super-insulated and air-tight, with mechanical ventilation to provide continuous fresh air from the outside. High performance triple-paned windows complement the building enclosure and maximize passive solar gain while ensuring a warm, draft-free winter, even when sitting close to the glass. A properly sized air source heat pump offers efficient heating & cooling, and includes a carefully designed the duct distribution system to provide even comfort throughout the house. The super-insulated envelope allows us to significantly reduce the equipment capacity, duct size, and airflow quantities, while maintaining unparalleled thermal comfort.
ENERGY EFFICIENT. The building’s shell and mechanical systems play instrumental roles in the home’s exceptional performance. The building enclosure reduces the most significant energy glutton: heating. Continuous super-insulation, thorough air sealing, triple-pane windows, and passive solar gain work together to yield a miniscule heating load. All active energy consumers are extremely efficient: an air source heat pump for heating and cooling, a heat pump hot water heater, LED lighting, energy recovery ventilation (ERV), and high efficiency appliances. The result is a home that uses 70% less energy than a similar new home built to code requirements.
OVERALL. The home embodies the owners’ goals and values while comprehensively enabling thermal comfort, energy efficiency, a vacation respite, and supplementary income.

Jennifer and Dan have lived in their Deer Park Illinois home for 15 years, slowly making minor fixes like painting and decorating; but they had a new plan for their kitchen the entire time. An awkwardly placed garage door, and an island cooktop with a terrible downdraft made a full-scale kitchen remodel an absolute must. Jennifer had many ideas in mind and wanted to work with a company that could provide high-end work, while partnering with a designer that would tailor the kitchen to her ideas.
She was intrigued by the phrase “Common Sense Remodeling” in Advance Design’s feature she discovered while perusing an issue of the community’s Quintessential Barrington Magazine. Doing further research on the company’s website, as she looked through project profiles and read about Advance Design’s “Common Sense Remodeling” philosophy, she promptly scheduled an appointment to see if the people and ideas she read about were truly who they said they were. The more she read, the more she knew that the “Common Sense” approach to remodeling they described was exactly the type of company she was looking for.
The partnership was sealed after an initial consultation with Owner Todd Jurs and Project Designer Michelle Lecinski. They displayed a combination of friendliness, professionalism and respect that was unmatched by any of the other companies Jennifer talked to. She knew that with Advance Design, she would be able to retain the vision that she had in mind with high-quality craftsmanship.
“I reached out to Advance Design because of the ‘Common Sense Remodeling’ tagline,” Jennifer said. “That’s what lingered for me”. “Advance Design was the most respectful- of the house and of my design ideas, and the most professional of the handful of companies that looked at my project”.
Soon after the meeting Jennifer began working with Michelle on the project design. They quickly developed chemistry. Jennifer loved how Michelle researched and located every detail that Jennifer wanted for the kitchen. Between the two of them, every concept and idea was worked through and perfected. “Jennifer had definite ideas about what she wanted the new kitchen to look like, she just didn’t know how to bring it all together. We worked together really well to make her ideas into the practical reality necessary for a well-functioning kitchen, with the look and feel that she had envisioned”, says Michelle.
“Michelle was wonderful in using the CAD system she would show me new drawings every time we changed the layout while working through the design,” Jennifer said. “She was a really wonderful partner in execution, she made sure everything happened quickly and easily.”
The finished design drew out elements of Jennifer’s style and personality. The pair call the look “sophisticated farmhouse” to describe the kitchen renovation to family and friends. The result was a beautifully crafted, authentic-feeling space that satisfied Jennifer’s dreams 15 years in the making. The whole project consisted of a kitchen remodel, mudroom upgrade with powder room, and garage entry relocation. “The projects I personally like the best, are the ones that put the client’s dreams on display,” Project Designer Michelle said. “And this is one of those projects.”
The main focal point of the kitchen is custom zinc and brass ventilation hood with a vintage sheen, which was hand made to order by a small company in Indiana named Vogler Metalworking. “It’s like sculpture, a true work of art”, says Jennifer. Your eye is immediately drawn towards this elegant yet practical hood that eliminated the home’s downdraft problem and added a striking conversation piece at the same time. The carpenters had to use special gloves when transporting and installing it, so they didn’t smudge it with fingerprints. The beautiful hood centers proudly over the stunning black enamel and brass LaCornue Range. “I had a friend who had a LaCornue range and after learning how easy it was to cook perfect meals, I was convinced I wanted to have one”, says Jennifer. This unique, breathtaking combination anchors the entire kitchen and is apparent immediately as you walk into the great room the surrounds the space.
DuraSupreme Crestwood cabinets with a Kendall Panel add function and sophistication. A custom gray paint color paired with a storm blue was developed so that the new kitchen looked like it belonged to the existing space. Unlacquered brass faucets and hardware were important to Jennifer because she wanted the living finishes to age over time. Remarkable brass diamond mesh cabinet door inserts imported from the UK continue to add this one-of-a-kind kitchen renovation; giving it a “you won’t see this everywhere” quality. The use of old railcar flooring for the coffee bar countertop and reclaimed oak for the open shelving gives an authenticity to the space uncommon in kitchens today.
Jennifer and Michelle fell in love with the Limestone Grey Stone while they were investigating unique island countertop ideas. They liked the fact that the limestone as a living finish will age and change over time. Calcutta Miel Quartz countertops made for an excellent pairing around the perimeter, as it’s durable and perfect for cooking preparations. A textured white subway tile backsplash that runs to the ceiling keeps your eye moving towards the open shelving, and to the main focal point of the stunning range hood combination.
“The kitchen functions beautifully, and it’s gorgeous,” beams Jennifer as she gestures with both hands while smiling ear to ear. “The most important thing was I wanted a kitchen that had a wonderful flow, cooked beautiful meals and was a great gathering place for family and friends, and this space does that perfectly! Beauty wise, it turned out exactly how I had envisioned. I felt the function part was the hardest part, and that was nailed”!
Relocating the garage entry to the new mudroom was a huge priority and has finally separated the family’s arriving home functions from their kitchen. Now coats and shoes and bags have their own area for dropping once members arrive home. Matching gray DuraSupreme cabinetry helped create gorgeous, purposeful lockers for the family. A reclaimed vintage sink and custom wall paper were added to the tiny powder room to beautify the once previously only functional space. Advance Design was even able to create a custom space for their dog to sleep while the family is away.
“It was unbelievable that a project of this size was completed in such a short time, and I think that’s because of the large amount of planning and preparation that went into it,” Jennifer marveled, “When we started, we were ready, and everything was prepared”.
When it came to execution, Project Manager Justin Davis and his crew were quick, accessible, and organized. Projects like this kitchen are typically completed in as little as 8-10 weeks. Jennifer’s kitchen however despite the relocation of some challenging HVAC in a soffit and moving of an exterior door was completed remarkably fast in part because the team was working with an existing tile floor that ran throughout the first floor that the client really loved.
“You get to know these people really well because they’re living in your house while you’re living in your house. They were so fast and really good, it didn’t take as long as even planned” reported Jennifer. “I would text Justin and he always responded almost immediately. I got to know all the guys who were working in our house and they were all wonderful people”.
Details in a customized kitchen like this one require skill and care from the people who install it. “All the guys on the job were skilled at what the did. I wanted small details like little feet to look like furniture, that is where their carpentry skill came in to make these all perfect”, said Jennifer. “The tile guys were wonderful. They even let me determine how I wanted the texture with the grout to appear for a salt and pepper look; now that is a very skilled trade person making it custom”.
In Jennifer’s interview, she continued to reference Advance Design’s “Common Sense Remodeling”, so I took a minute to ask her exactly what that phrase meant to her and how it played out in her experience with her project and the Advance Design team. Here is what she said: “I was intrigued about Common Sense Remodeling and in my head that there would be clear costs and prices, great communication between the design team, the execution team and me”, said Jennifer. They did deliver on that, it was so clear about the cost breakdown, what I could expect from everyone who came to my house, and everything that we had ordered. That to me is the Common Sense”!
It’s great to see a client take literally our assertion that a well-planned remodeling project is simply “Common Sense”! She anticipated each step of the way would be clear, concise, and predictable, all the while protecting the outcome due to the careful upfront planning. “Advance Design delivered on their ‘Common Sense Remodeling’ promise,” Jennifer said. “From the design team, to the execution team - everything was straight forward like I imagined. The project turned out exactly how I envisioned, I enjoyed this process and absolutely would recommend Advance Design Studio to anyone.”

This modern farmhouse located outside of Spokane, Washington, creates a prominent focal point among the landscape of rolling plains. The composition of the home is dominated by three steep gable rooflines linked together by a central spine. This unique design evokes a sense of expansion and contraction from one space to the next. Vertical cedar siding, poured concrete, and zinc gray metal elements clad the modern farmhouse, which, combined with a shop that has the aesthetic of a weathered barn, creates a sense of modernity that remains rooted to the surrounding environment.
The Glo double pane A5 Series windows and doors were selected for the project because of their sleek, modern aesthetic and advanced thermal technology over traditional aluminum windows. High performance spacers, low iron glass, larger continuous thermal breaks, and multiple air seals allows the A5 Series to deliver high performance values and cost effective durability while remaining a sophisticated and stylish design choice. Strategically placed operable windows paired with large expanses of fixed picture windows provide natural ventilation and a visual connection to the outdoors.

A uniform and cohesive look adds simplicity to the overall aesthetic, supporting the minimalist design of this boathouse. The A5s is Glo’s slimmest profile, allowing for more glass, less frame, and wider sightlines. The concealed hinge creates a clean interior look while also providing a more energy-efficient air-tight window. The increased performance is also seen in the triple pane glazing used in both series. The windows and doors alike provide a larger continuous thermal break, multiple air seals, high-performance spacers, Low-E glass, and argon filled glazing, with U-values as low as 0.20. Energy efficiency and effortless minimalism create a breathtaking Scandinavian-style remodel.

ZeroEnergy Design (ZED) created this modern home for a progressive family in the desirable community of Lexington.
Thoughtful Land Connection. The residence is carefully sited on the infill lot so as to create privacy from the road and neighbors, while cultivating a side yard that captures the southern sun. The terraced grade rises to meet the house, allowing for it to maintain a structured connection with the ground while also sitting above the high water table. The elevated outdoor living space maintains a strong connection with the indoor living space, while the stepped edge ties it back to the true ground plane. Siting and outdoor connections were completed by ZED in collaboration with landscape designer Soren Deniord Design Studio.
Exterior Finishes and Solar. The exterior finish materials include a palette of shiplapped wood siding, through-colored fiber cement panels and stucco. A rooftop parapet hides the solar panels above, while a gutter and site drainage system directs rainwater into an irrigation cistern and dry wells that recharge the groundwater.
Cooking, Dining, Living. Inside, the kitchen, fabricated by Henrybuilt, is located between the indoor and outdoor dining areas. The expansive south-facing sliding door opens to seamlessly connect the spaces, using a retractable awning to provide shade during the summer while still admitting the warming winter sun. The indoor living space continues from the dining areas across to the sunken living area, with a view that returns again to the outside through the corner wall of glass.
Accessible Guest Suite. The design of the first level guest suite provides for both aging in place and guests who regularly visit for extended stays. The patio off the north side of the house affords guests their own private outdoor space, and privacy from the neighbor. Similarly, the second level master suite opens to an outdoor private roof deck.
Light and Access. The wide open interior stair with a glass panel rail leads from the top level down to the well insulated basement. The design of the basement, used as an away/play space, addresses the need for both natural light and easy access. In addition to the open stairwell, light is admitted to the north side of the area with a high performance, Passive House (PHI) certified skylight, covering a six by sixteen foot area. On the south side, a unique roof hatch set flush with the deck opens to reveal a glass door at the base of the stairwell which provides additional light and access from the deck above down to the play space.
Energy. Energy consumption is reduced by the high performance building envelope, high efficiency mechanical systems, and then offset with renewable energy. All windows and doors are made of high performance triple paned glass with thermally broken aluminum frames. The exterior wall assembly employs dense pack cellulose in the stud cavity, a continuous air barrier, and four inches exterior rigid foam insulation. The 10kW rooftop solar electric system provides clean energy production. The final air leakage testing yielded 0.6 ACH 50 - an extremely air tight house, a testament to the well-designed details, progress testing and quality construction. When compared to a new house built to code requirements, this home consumes only 19% of the energy.

The open space plan on the main level of the Prairie Style home is deceiving of the actual separation of spaces. This home packs a punch with a private hot tub, craft room, library, and even a theater. The interior of the home features the same attention to place, as the natural world is evident in the use of granite, basalt, walnut, poplar, and natural river rock throughout. Floor to ceiling windows in strategic locations eliminates the sense of compression on the interior, while the overall window design promotes natural daylighting and cross-ventilation in nearly every space of the home.
Glo’s A5 Series in double pane was selected for the high performance values and clean, minimal frame profiles. High performance spacers, double pane glass, multiple air seals, and a larger continuous thermal break combine to reduce convection and eliminate condensation, ultimately providing energy efficiency and thermal performance unheard of in traditional aluminum windows. The A5 Series provides smooth operation and long-lasting durability without sacrificing style for this Prairie Style home.

This is the completed house.
