Built around 1890, the original shingle and stone cottage was extensively renovated and expanded by the architect-owner in the 1930s, and when the new owners bought it in 2020, it was still largely untouched from this period. After spending some time in the house, the new owners quickly realized the potential to turn the dark and inwa… - [EASY BEING GREEN](https://www.houzz.com/hznb/projects/easy-being-green-pj-vj~6560139) - Location: Portsmouth, NH - Photos: 6 - Description: This modern farmhouse seamlessly blends into wooded landscape near the ocean, the ideal location for a home that minimizes energy use. The homeowner’s wish to downsize while maintaining a sustainable lifestyle was met with a new three-story residence within a robust building envelope, reducing heat loss and lessening energy use. Site orientation of the building was carefully navigated to maximize the land’s sustainable offerings and site construction was timed to begin during autumn to avoid dis… - [GREAT ISLAND INN](https://www.houzz.com/hznb/projects/great-island-inn-pj-vj~6120954) - Location: New Castle, NH - Photos: 4 - Description: A drastic renovation transformed an unkempt 1800’s-era residence on New Castle Island into a sleek, modern apartment-style inn. In addition to the renovation, the third floor was completely rebuilt. Now, six elegantly designed guest studios, including one fully accessible unit, offer travelers fully equipped kitchens, personal concierge services and in-room laundry facilities. In addition to design work, Lassel Architects coordinated with civil engineers and the landscape architect on an outdoor… - [LAKESIDE GETAWAY](https://www.houzz.com/hznb/projects/lakeside-getaway-pj-vj~6120673) - Location: Acton, ME - Photos: 17 - Description: This private home was designed to be reminiscent of traditional Maine lodges and family camps. Lassel Architects worked closely with the homeowners to provide a meticulously crafted home to serve as a sanctuary for their large family. The open-concept plan, wrapped in a unique timber frame inspired by early 20th century architects Greene and Greene, provides spaces suitable for entertaining with generous views to the lake. Bedrooms and loft sleeping spaces were configured to maximize water views… - [REFLECTIVE RENOVATION](https://www.houzz.com/hznb/projects/reflective-renovation-pj-vj~6120951) - Location: Portsmouth, NH - Photos: 3 - Description: Sitting along the Piscataqua River in the historic south end of Portsmouth, New Hampshire, this home has charming views of islands and moored sailboats. The homeowners found themselves constantly drawn to the front of the house to take in the views. Unfortunately, the existing wrap-around porch could only be used three months out of the year and was too narrow to accommodate comfortable furniture. Lassel Architects designed an enclosed sunroom that could be enjoyed year-round while being sensiti… - [STURGEON CREEK](https://www.houzz.com/hznb/projects/sturgeon-creek-pj-vj~6120947) - Location: Eliot, ME - Photos: 7 - Description: Situated on a nine-acre parcel, this home overlooks Sturgeon Creek, a waterway directly connected to the Piscataqua River in Eliot, Maine. Lassel Architects worked closely with the homeowners to build the home to fit in with the natural landscape while working within strict river and wetland setback restrictions. The home augments views to the active creek and lush landscape. The juxtaposition of the home on the site preserves privacy by limiting the visual impact of the street on interior space… [See all 6 projects](https://www.houzz.com/professionals/architects-and-building-designers/lassel-architects-pfvwus-pf~940438247) --- *Source: Houzz professional profile.
