"I couldn't have expected a better service, and that's after using several engineers in the tri-state for past work. This engineer also goes above and beyond. He is meticulous, honest and very responsive. He was truly a pleasure to deal with. I will absolutely be using him again, and I wholeheartedly recommend him.

"The construction company, MGT Construction has just completed our +/-600 sq foot deck at our home in Southold. MGT managed the planning: We were determined to build the deck per Southold Town code using Timber-Tech composite decking and railings per their specifications. After we had the survey done Steven coordinated with their architect and liaised all building inspections. He was instrumental in all follow-ups with the town until final approval of the permit. We sourced the pressure-treated framing lumber from Amagansett Lumber and with four feet deep footings the underlying structure is solid and constructed to last 30 years, which is also the guaranteed life of the decking. MGT Construction excels in the carpentry aspect of the decking. They made sure the planks were correctly aligned and the surrounding picture frame planks were precisely fitted. This was also true as well regarding the fitting of the railings. We opted for “drink rails” and their finishing on those is superb. Our overall impression of the construction staff was that they were always courteous and friendly. We did however make the observation that the workers should pay attention to their attire, which at times was needlessly sloppy and awkward. However, they were hard workers and respectful. An electrical subcontractor had to redo work because a supervisor was not on the site. The work was corrected and promptly made without complaint. Cleanup was done in a timely manner and to our satisfaction. Having had other construction work done on homes I can honestly say, MGT Carpentry was professional and their work was excellent. I highly recommend them."

"I came across Mark Michaels and Great Designs by doing a Google search for Stony Brook Architects. I viewed his web site and looked at the work he had done for other clients.. I was impressed so I contacted him via email with my details and received a phone call back from him later that same day. We discussed how my wife and I had recently purchased this house and wanted to make some changes to it. The house is on a nice parcel of land with a water views and beautiful sunsets, however it is quite unique and a bit eclectic. The house also posed zoning difficulties as it is situated against the back of an oddly shaped lot. Our objective was to add a first floor master bedroom and bath without losing any of the existing water views.
My wife and I met with Mark and showed him the house. He shared his initial thoughts and observations and we agreed to take the next step. Mark prepared a proposal for his services which we thought were quite reasonable. We agreed to move forward.
Mark made several visits to the house, took measurements and made notes. He even video taped the house. The house has two levels but the layout is one of a kind. There are many nooks, odd shaped rooms and changing elevations. Mark took all this information and somehow entered it perfectly into his architectural software. He then used these tools to illustrate how the planned addition would look and its impact on the entire home. We were able to do a virtual tour of the inside and outside of the proposed structure. We quickly became comfortable with the design and moved to the next stage.
Mark prepared extensive building documents which we used to get contractor bids. I also was able to walk into the building department and leave with a building permit on the first visit. We hired a contractor and the project progressed smoothly. Mark made frequent visits to the site and really took ownership of his work. Several of the tradesmen commented to me how impressed they were with his passion for the project, his attention to detail and the integrity of his design.
Well, as of this writing the project is well on its way to completion. It has been a positive experience. My wife and I highly recommend you give Great Designs a look.
