Verified record
Shelter 7 is a Nantucket design-build firm run by Jason Olbres and Nichole Marks, doing the kind of work that spans architecture through construction — new custom homes, full renovations, additions, and house plans — for a coastal island clientele. The company's written record, eleven reviews on Houzz running from 2013 through 2017, describes real, specific projects rather than one-off praise: a 2017 review from a family that had just moved into a new home Cameron's crew built on time, designed by Jason and Nichole, calling the whole process something they couldn't be happier with; a 2017 review from a Nantucket design/build client who called the entire team courteous, knowledgeable, and professional start to finish; a 2016 review describing a full home renovation where the workmanship and professionalism exceeded expectations, with the reviewer saying they think about the company regularly since. Several reviewers came back for more than one job — one 2013 review describes four or more projects together over time, consistently impressed by the design and craftsmanship — and a 2016 client who'd had an HVAC system installed was already planning to bring the company back to build an additional structure. A handful of the positive accounts come not from homeowners but from industry collaborators: a lighting supplier and a plumbing and fixtures supplier who worked with Shelter 7 across multiple projects both describe the team as a pleasure to deal with, which speaks to how the company works with other trades as much as with clients directly. Houzz shows a perfect 5.0-star average across all eleven reviews, and BuildZoom lists an active Massachusetts Home Improvement Contractor license (#191304) for the business, matching the address and ownership shown on the company's own site. Directory listings show a few different phone numbers across platforms, but the matching address, owner names, and near-identical self-description make clear these all describe the same company rather than a mix-up. One thing worth flagging plainly: the entire written record here predates 2018 — there's nothing more recent on file to speak to how the company operates today, even though the license listing suggests it's still active. For a full custom build, a substantial renovation, or an addition on Nantucket, the historical record here describes a design-build team capable of ambitious, well-executed projects and repeat client relationships — just confirm current availability and see recent project photos, since the written reviews themselves stop in 2017.
We just moved into our new home built (on time) by Cameron with his super hard working team of highly skilled craftsmen, designed by Jason and Nichole from Shelter 7 Design and we could not be happier with the process and the result. Before seeking out and deciding to hire Shelter 7 we saw homes that they had built or worked on and always felt that they stood out as beautiful, cozy and unique before learning who the architect/builder was. The attention to detail, respect for our lifestyle and wishes makes our home ideal. We have never before experienced such high quality workmanship and consideration on a build. It's thanks to their complete professionalism and unique style that we could go beyond our imagination to build a home of the quality we have. Absolutely - we would be over the moon to work with Shelter 7 again and can unreservedly recommend them to potential clients.
We worked with Shelter 7 on a design/build project in Nantucket, MA. We were impressed with every aspect of working with Jason and his entire team. Not only were they courteous, knowledgeable and professional, but they were a pleasure to work with from start to finish. The amount of time and pride put into our project was nothing less than astounding. Our home is a reflection of all of that, and we love it. The best compliment I can give is that we enjoyed working with Shelter 7 so much that we asked them 3 years later to design a project off-island with us. I am happy to say the second time working with Shelter 7 has been just as positive. We highly recommend Shelter 7 to anyone considering a project in Nantucket (or in Boston) if they are willing to work off-island again.
Shelter 7 is an outstanding company and did a great job at our house. They installed an HVAC system in our house and were extremely professional and a pleasure to work with. We are working with Shelter 7 now to build an additional structure at our house. I HIGHLY recommend Shelter 7!
My husband and I hired Shelter 7 to renovate our home. The quality of the workmanship and professionalism from the whole team was beyond our expectations. I would highly recommend them for a renovation or a new build project. There is not a day that goes by that we don't think how much we love our house!
Great market advise, inspirational team, acute precision to detail, craftsman finish work - Overall a great team to work with Start to Finish
