Shelter 7 is a boutique residential design-build firm based on Nantucket Island, Massachusetts, run by owners Jason Olbres and Nichole Marks. The company handles a project from architectural design through construction, and also operates a caretaking division for ongoing home maintenance and emergency service. It holds an active Massachusetts Home Improvement Contractor license. Every review on file, eleven in total across the firm's Houzz profile, gives Shelter 7 the full five stars, and several describe specific, first-hand experiences rather than general praise. In an October 2017 review, a homeowner described moving into a new home built on time by general manager Cameron and his team, designed by Jason and Nichole. Another reviewer who hired the firm for a Nantucket design-build project in 2017 was pleased enough to rehire them three years later for an off-island project. A 2012 review credits Jason with a creative redesign that reused an existing building's footprint, eliminating the need for a costly addition the homeowners had originally planned. Trade partners have echoed the same theme: a lighting supplier and a plumbing and fixtures supplier, both writing in 2013 and 2014, described the firm as detail-oriented and a pleasure to work with across multiple projects. A 2016 review also credits the team with an HVAC system installation. Worth asking about before booking: the newest of the eleven reviews on record dates to October 2017, so there is no verified customer feedback from the last several years -- worth confirming the team and quality have stayed consistent since then. Contact information also differs across sources: the firm's own website lists (508) 325-7770, its BuildZoom profile lists (508) 315-7770, and its Houzz profile lists (978) 764-6802. The address and owner names match on all three, so this looks like directory data drift rather than a sign of a different business, but it's worth confirming the current number directly before reaching out. Shelter 7 looks like a solid fit for a homeowner on or near Nantucket planning a substantial design-build project -- a full remodel, addition, or new custom home -- who wants one firm managing design and construction together, backed by a consistent, if dated, record of five-star client and trade-partner feedback. Confirm current contact details and recent project references directly with the firm.
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.
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... 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.
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.
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.
