I run 30X40 Design Workshop a modern architecture practice located on Mount Desert Island. I'm inspired by agricultural structures and industrial materials, simple forms, and design born out of a narrative story. While my architecture aesthetic is outwardly simple, each project crafts a story about a specific client, in a specific time, and a specific place, using high quality materials. I find this results in a wonderfully engaging process and a more meaningful home. For more of my work, please see my website: http://thirtybyforty.com for a portfolio of selected projects, plan sets available for purchase, my video tutorials, blog, and publication list. I'm an award-winning licensed Architect licensed in Maine with a national certification from NCARB. ### Services Provided - Architectural Design - Custom Homes - House Plans - New Home Construction - Sustainable Design - Floor Plans - Energy-Efficient Homes - 3D Rendering - Site Preparation - 3d home design ### Areas Served - Bar Harbor - Trenton - Southwest Harbor - Tremont - Swans Island - Northeast Harbor - Sorrento - Cranberry Isles - Bernard - Mount Desert - Salsbury Cove - Seal Harbor ## Business Details | Field | Value | | --- | --- | | Business Name | Eric Reinholdt, Architect | | Address | 12 Brendun Lane, Mount Desert, Maine 04660, United States | | Phone | (207) 244-3373 | | Website | http://thirtybyforty.com | | License Number | ARC2823 | | Followers on Houzz | 1298 | **Social profiles:** - Facebook — https://www.facebook.com/30x40DesignWorkshop - X (Twitter) — https://twitter.com/EricReinholdt - LinkedIn — http://www.linkedin.com/pub/eric-reinholdt/1/ba7/139 - Blog — http://thirtybyforty.com/blog/ ## Contact - **Houzz profile:** [Eric Reinholdt, Architect](https://www.houzz.com/professionals/architects-and-building-designers/eric-reinholdt-architect-pfvwus-pf~470387197) - **Website:** http://thirtybyforty.com - **Phone:** (207) 244-3373 ## Credentials **Certifications & Awards** - NCARB CertifiedLicensed Maine ArchitectAwards: see http://thirtybyforty.com/awards-publications/ - **Best of Houzz:** 3 awards (2014–2015), for Design, Service. **Affiliations** - [NCARB](https://www.houzz.com/professionals/schools-and-organizations/ncarb-pfvwus-pf~1477640315) ## Reviews **Overall rating: 5.0 out of 5 — 9 reviews** ### All 9 reviews **★★★★★ — User, Oct. 2016** > A few months ago I enjoyed working with Eric on modifying and adapting his Longhouse 2.0 design to fit my needs. He was very receptive, offering several options and recommendations in a timely manner, each time ensuring that I was satisfied with the modifications. Thank you Eric for making it a simple and easy experience, and for making accessible and affordable high quality design. **★★★★★ — DiMare Design, Jan. 2016** > I am an interior designer and am a huge fan of Eric's work. His designs are timeless, simple and truly elegant. As an interior designer I understand that creating simplicity requires tremendous knowledge, skill and sheer talent. If you look at Eric's designs, they encompass everything an accomplished architect should be. Beautiful work Eric. **★★★★★ — Chain & Asociados, Jan. 2016** > I have read two of Erics books, Architect Entrepreneur 1 and Guide to Houzz. As a architect and business owner I can say his advise is spot on! I am eager to put into practice many of his marketing tips into growing my practice. **★★★★★ — Alesi Design, July 2015** > Eric is a great architect and has excellent communication skills. The books he wrote have helped many colleagues, including me, to take their first steps in the new world of architecture in the era of social media. Thanks Eric, greetings from Rome. > > Umberto **★★★★★ — Warmboard Radiant, Feb. 2015** > We have been blown away by Eric's knowledge of architecture, design and construction. We admire not only the dedication to his craft, but his integrity and work ethic. Finding an architect like Eric is a real treat; one who pushes himself creatively, relentlessly pursuing new trends and technologies while showing a consistent dedication to educating his clients and the population at large. We work with thousands of architects across the country. And Eric is definitely one of those stands out in the crowd. We are anxious to work on more projects with him in the future. **★★★★★ — gobrien1, May 2014** > I found Eric through one of his images on Houzz. I was looking for an Architect to design a studio on the same property as my main home. All I can say was it was a excellent experience. I used architects in the past for other projects and it was not as smooth or enjoyable as working with Eric. He guided me through the pro and con of each idea and presented alternative solutions to each problem. I would use Eric again on any future projects I have. **★★★★★ — ddprothero, March 2014** > Eric is an absolute pleasure to work with. For the last 9 Months he has worked on a variety of project for us. From a whole building design to a simple green house and lower level meeting space. All have been approached with the same passion, dedication to quality, and diligence. His ability to present design options that simply make sense separates him from the chaff. Scale and composition are concepts he applies to design, not simple buzz words at a cocktail party. If you’re looking for a talented, hardworking designer, get in contact with Eric. **★★★★★ — jacobbearden, Feb. 2014** > I have recently had the pleasure of working with Eric on modifying the Longhouse 3.0. His designs are simple yet modern with a strong emphasis on materials and details. Eric is very responsive to changes to his plans and offers great ideas on how to make them work for you. His communication is great and he makes you feel comfortable talking about design with him. I would strongly recommend Eric to anyone wanting thoughtful architectural design that can be attained by the average person wanting more than the status quo in housing. Cheers to Eric! **★★★★★ — damonlear, Nov. 2013** > As a contractor and project manager I've worked on several projects with Eric Reinholdt, and hope that there are more in the future. He has been an integral part of the team on every venture; providing skilled and experienced design work for the clients, and accurate and timely information to the tradesmen on site. Accessibility and attention to detail mean everything to construction projects, and I've found no one better than Eric on those fronts. > Eric has a firm grasp on both architecture and project execution, and has shared my obligation to client satisfaction on all projects. The clients count on his architectural ability, and I count on his technical ability... he hasn't failed yet. ## Selected projects - [Pond House](https://www.houzz.com/hznb/projects/pond-house-pj-vj~367562) - Location: Not specified - Photos: 19 - Description: Eric Reinholdt - Project Architect/Lead Designer with Elliott + Elliott Architecture This building marries the familiar with the unexpected in an unusual site at the edge of a harsh sea environment.

The building was conceived of as three distinct volumes each positioned to maximize natural light, views, and privacy and connected to each other via a series of flat roofed interior breezeways. Upon arrival to the site, one leaves their car parked higher on the hill away from the view in a small court. Proceeding down several steps the entry opens to the central volume, the largest of the three… - [Portfolio](https://www.houzz.com/hznb/projects/portfolio-pj-vj~324331) - Location: Mount Desert Island, ME - Photos: 13 - Description: A few of the projects I've been the lead designer / project architect on - for a more detailed collection of my work and designs available for purchase please refer to my website: http://thirtybyforty.com/ - [Seal Cove Bunkhouses](https://www.houzz.com/hznb/projects/seal-cove-bunkhouses-pj-vj~751073) - Location: Not specified - Photos: 13 - Description: Borrowing from the image of the platform tent, two seasonal, guest cottages share a linear cedar deck and are grouped in dialogue marking a clearing in the forest.

The studio is equipped with a bath and shower to double as a guest sleeping space, writing area, workshop, or media room. The detached nature of the structure builds in physical separation in a small floor plan – a key to making it live and feel larger than it is. The narrow eighteen foot width allows light into the full depth of the plan and brings your living spaces close to the outdoors.
