TMS Turns 41

1984. Gas was $1.13, the Celtics won an epic game 7 against the Lakers to earn the title of 35th NBA Champion, and the original Apple Macintosh personal computer went on sale. This also happened to be the year that TMS was founded (the most significant fun fact, if you ask us. Who needs computers, anyway?).

41 years ago, William “Bill” Soupcoff and John Merkle joined together to create what is now TMS Architects & Interiors, a boutique home design firm servicing New Hampshire, Maine, Massachusetts, and beyond, to create wonderfully unique and luxurious homes.

From the jump, Bill and John shared a common passion for architectural design and both heavily valued ethics, fairness, and the insistence of superior work quality. Coming from different backgrounds (John graduated from NYIT; Bill from MIT), these two took their shared interests and unique educations and created a partnership that resulted in some of the finest architectural work in New England. Some projects you may recognize if you are local to the New England seacoast area include the Wentworth by the Sea Hotel restoration, the Music Hall restoration, and the Bridges House, as well as many stunning residential projects that pepper the coastal, lakefront, and inland roads of the region.

As the decades have passed, there have been monumental changes within the industry and the world in general, but TMS’ values have remained the same. Our mission is to fully embrace our clients’ visions and turn them into buildings that are beautiful, functional, and sustainable. Whether it’s a residential build, a pool house renovation, or commercial office design, communication and attention-to-detail are critical.

Considering the growth of technology since 1984, our founders established the TMS name when architects primarily relied on hand-drawn sketches. We are now able to take clients on a three-dimensional tour of their future homes thanks to virtual reality. How times have changed! (although many of our designers still enjoy creating by hand). As technology and our business have developed, so have our skills, capabilities, and portfolio. We have worked to establish ourselves as both an architectural firm and an interior design firm, collaborating with clients in all phases of the design process. Whether in the initial construction phase or in the final decorating phase, we set out to not only meet our clients’ expectations but exceed them.

Over the years, our work has earned us more than 40 awards for excellence of design. These projects have ranged from a 2004 National Trust for Historic Preservation Award for our work on the restoration of the Wentworth by the Sea Hotel (spearheaded by John Merkle, our initial historic preservation enthusiast!) to the 2025 Modern Luxury Interiors New England award for Best NH Architect. These awards and the variation of them display just how much time, thought, and energy goes into understanding what our clients desire for each project. and teaming up with them every step of the way to achieve just that. We are honored to have been serving our community for 41 years, and we look forward to the new projects we have yet to take on. Thank you to everyone who has helped make TMS Architects & Interiors into what it is today (employees, clients, family, community, etc) and here’s to the continuation of beautiful, unique, and sustainable building design!
