Boston’s oldest preserved neighborhood presents a dilemma for electric vehicle adoption. Federal-style brownstones along Louisburg Square house residents who drive Teslas but lack infrastructure to charge them without compromising protected architectural character. Chris Rapczynski, founder and president of Sleeping Dog Properties, has developed a solution that conceals Level 2 charging capability beneath 19th-century streetscapes.
Rapczynski’s team installed Tesla Wall Connector infrastructure beneath Louisburg Square’s brick sidewalks, routing 240-volt electrical service through a custom utility box designed to mimic traditional gas equipment. “We’re installing a Tesla car charging station underneath the brick sidewalk into a historic custom-made utility box that’s designed to look like a gas box, but instead of saying ‘gas,’ it says ‘EV,'” he explains. After three decades managing over $500 million in construction projects, Rapczynski understands how to navigate regulatory constraints while delivering up to 44 miles of range per hour charging capability.
Louisburg Square stands among America’s most restrictive preservation environments. Federal and Greek Revival brownstones designed by architects including Asher Benjamin and Alexander Parris require approval from Beacon Hill Architectural Commission for any exterior modifications visible from public ways. Expansion of Historic Beacon Hill District in 2024 brought its northern border to Cambridge Street, incorporating additional properties between Charles River Circle and Bowdoin Street.

Engineering for preservation standards
Historic district regulations in Beacon Hill examine every exterior detail visible from Boston Common, Public Garden, Storrow Drive, and Charles River Esplanade. Violations require expensive remediation that can compromise both project budgets and neighborhood character. Rapczynski experienced this firsthand when a contractor made an unauthorized modification. “One of my plumbers drilled a hole through the front of a building to put a vent pipe, and we all knew it was wrong. Everybody knew it was wrong, and I had to go patch it back and match the mortar and match the brick to the period of time.”
Such experiences informed approaches for Tesla charging project planning. Rather than installing standard EV pedestals that would disrupt Louisburg Square’s Federal-era aesthetic, Sleeping Dog Properties developed underground infrastructure accessed through period-appropriate utility hardware. Custom fabrication ensured both Tesla’s technical specifications and commission visual requirements were satisfied.
Installation required coordination with multiple authorities, including Beacon Hill Architectural Commission, Boston utilities and Massachusetts Historical Commission. Excavation beneath brick sidewalks required the installation of 6-gauge wire within protective conduit, proper grounding systems, and waterproofing measures for underground electrical components. Rapczynski’s experience with Boston’s preservation bureaucracy proved essential for securing approvals while meeting National Electrical Code requirements for 50-amp circuit breaker installation.
Boston’s broader electric vehicle expansion provides context for this innovation. Federal grants totaling $15 million announced in August 2024 will fund at least 300 EV charging ports citywide through Recharge Boston program, which aims to place every household within a five-minute walk of public charging. However, most installations target modern streetscapes rather than historic districts with preservation constraints.
Advanced lighting technology in historic interiors
Beyond EV infrastructure, Rapczynski has developed lighting systems that enhance historic properties without compromising their character. His approach involves color temperature matching that automatically adjusts interior lighting to exterior conditions. “Nobody used to know that an incandescent light bulb is 2,700 Kelvin. Now every lightbulb that we buy, every light fixture we buy can be 2,700, 3,000, 3,300, 4,200, 6,000,” Rapczynski notes about lighting technology advancement.
Modern systems can match exterior color temperatures—ranging from 6,000 Kelvin during bright sunny conditions to 2,700 Kelvin during warm evening light—with interior environments. “They make a fixture, a light fixture that matches the outdoor color temperature. So if the outdoor color temperature on a sunny day is 6,000 Kelvin, let’s just say, or whatever it is, mixed with some 2,700 moments, it will match the exterior lighting temperature with the interior lighting environment so that you do not feel the separation between your outdoor and indoor space.”
Initially skeptical about such systems, Rapczynski changed his perspective after experiencing results. “I thought to myself, what a waste of money, when I first saw the idea of it. But then I went and experienced it and I thought, oh my God, this is a game changer.”
Creative problem-solving in historic constraints
Rapczynski’s philosophy emphasizes collaborative innovation when facing preservation challenges. “What I love the most is those client interfaces, where the dynamic of problem solving is working with a small group of people, architect, interiors, the homeowner to come up with the best solutions for the owner’s end game. That dialogue is really satisfying to me,” he explains.
One memorable example involved transforming an antique washbasin bucket into a functional sink that resembled a barn fixture, despite plumbing code restrictions. “We wound up coming up with ways to do that. And it was a small project, but the guy was really dynamic, and we achieved getting his goal,” Rapczynski recalls.
His firm has developed expertise in energy efficiency improvements that dramatically reduce operating costs without visible modifications to protected facades. “We’ll build a house, a 5,500-square-foot house. We’ll have all high-efficiency boilers and heating systems and hot water heaters and light fixtures, and it’ll cost maybe $2,000 a year to heat and cool and hot water and lighting and everything,” he notes.
Precedent for infrastructure adaptation
Beacon Hill became Massachusetts’ first designated historic district in 1955, establishing preservation standards that have protected Federal-style architecture for seven decades. District expansion in 2024 demonstrates continued commitment to protecting historical character despite development pressure. Rapczynski’s charging station project establishes precedent for infrastructure adaptation within such constraints.
“Sometimes we talk about where does this go in the future, because are we going to have electric car charging stations in front of every historic home? Is that where this is headed, and how does that get managed?” Rapczynski notes. His approach demonstrates that preservation and technological advancement can advance simultaneously through careful design and regulatory coordination.
Boston City Councilor Sharon Durkan emphasized particular challenges facing historic neighborhoods during February 2024 City Council discussions about EV infrastructure expansion. “The people I’ve heard from the most about lack of access are those from historic neighborhoods,” she said. Rapczynski’s solution addresses access gaps without compromising architectural integrity.
Technology integration without visual impact
Standard EV installations rely on prominent charging pedestals that would compromise Louisburg Square’s protected character. Rapczynski’s underground approach maintains full Level 2 charging functionality while preserving one of America’s most photographed historic streetscapes. “All those people who are living in there, in those communities, are now wanting to answer their lifestyle needs,” Rapczynski observes.
“Sometimes people just think because it’s old, it’s valuable, but that’s not necessarily the case. It could just be old and awful,” Rapczynski notes about preservation decision-making. His approach emphasizes informed analysis over assumptions, ensuring technology integration decisions reflect genuine historical significance rather than reflexive opposition to change.
Chris Rapczynski’s Tesla charging innovation in Louisburg Square demonstrates that historic preservation and technological advancement can proceed simultaneously through careful planning and creative design. His work establishes a framework for infrastructure adaptation that cities nationwide can adopt as they balance heritage protection with contemporary needs.
