The ultimate in healthy living.

Our most recent project, Highland Street, was a total reimagination of a classic late 19th century Victorian farmhouse. Retaining the well-proportioned and attractive main 1897 house, we removed a 1960s-era wing and replaced it with larger and more appropriate living spaces in the New England farmhouse vernacular. A new three-car garage with living space above took the place of the detached vintage garage/barn.  We lifted the house and installed a new foundation and finished basement to provide additional living space and improve the home’s efficiency.

Position yourself at the leading edge of sustainable design.

The house was modernized using best-practice building science principles to include a super-insulated and air-tight exterior envelope, high-efficiency heating, air-conditioning, and hot water systems, a mechanical ventilation system, low-consumption water fixtures, and high-performance windows and doors. Careful landscape design with natural and adapted plants reduces irrigation demand and maintenance.  Interior materials and finishes were specially selected from low-VOC, low-formaldehyde products to ensure healthy indoor air quality.  A 14.72 kW solar PV array and extensive smart house package put this home at the cutting edge of residential technology.

Designed with today’s family in mind.

This project has been certified LEED Platinum®by the U.S. Green Building Council. The LEED rating system, developed by the U.S. Green Building Council (USGBC), is the foremost program for buildings, homes and communities that are designed, constructed, maintained and operated for improved environmental and human health performance. A home can achieve LEED certification under the LEED for Homes program after undergoing a technically rigorous process, including the incorporation of green strategies to achieve efficiency and healthy indoor environments. The sound design and operation of the home is tested and measured using tools like a home energy (HERS) rating and onsite inspections.

Optimized for living.

In addition, this project has met the strict standards of the EPA ENERGY STAR®  Program, the EPA Indoor airPLUS Program, and the DOE Zero Energy Ready HomeProgram, and has been certified in each program.

LEED Platinum®
LEED Platinum®

LEED for Homes is a rating system that promotes the design and construction of high-performance green homes. Administered by the U.S. Green Building Council, LEED certification offers a holistic approach to sustainability and emphasizes strategies for better environmental and health performance. LEED buildings are constructed using designs and processes aimed at saving energy, water and money, and providing healthier and more comfortable indoor environments for the people who use them.


A new home or apartment that has earned the ENERGY STAR label has been verified to meet strict energy efficiency requirements set by EPA. ENERGY STAR certified homes are at least 10% more energy efficient than homes built to code and achieve a 20% improvement on average, while providing homeowners with better quality, performance, and comfort. Highland Street is an ENERGY STAR certified home.

EPA Indoor airPLUS
EPA Indoor airPLUS

Indoor airPLUS is a voluntary partnership and labeling program that helps new home builders improve the quality of indoor air by requiring construction practices and product specifications that minimize exposure to airborne pollutants and contaminants. Clean air is good for everyone’s health, but it can be especially important to those that have chronic respiratory conditions. Highland Street has been qualified to meet Indoor airPLUS.

DOE Zero Energy Ready Home
DOE Zero Energy Ready Home

A DOE Zero Energy Ready Home is a home that meets all of the criteria found in the DOE Zero Energy Ready Home National Program Requirements. DOE Zero Energy Ready Homes are verified by a qualified third-party and are at least 40%-50% more energy efficient than a typical new home. This generally corresponds to a Home Energy Rating System (HERS) Index Score in the low to mid-50s, depending on the size of the home and region in which it is built. Highland Street has achieved DOE ZERH certification.
