Dear T.J., I wanted to thank you again for all you’ve done to make our project such a success. I also wanted to say thank your for the beautiful flowers for the Women’s Club event held here. I must say all the ladies certainly loved the work you did, and will want to meet with you! I also wanted to extend an offer to have an informal open house anytime with your team, Brian Honahan and Bobby Lambaskis to showcase your work. I would love t o help in any way, thanks again for everything.

TJ Costello of Hierarchy Architects & Designs created an amazing back porch for my Georgian Center Hall Colonial home a few years ago. His designs were in keeping with the traditional style of the house. From the slate roof, to the crown molding, to the real brass screens, every detail was beautiful. TJ stayed close to the complete renovation as the construction took place. The finished project was featured in This Old House Magazine, but more importantly, it gave my husband and I a great new space to sit and chill. While it might have been one of TJ's smaller projects, but he put a great deal of effort into it on our behalf.

We found him to be very receptive and kept involved during the development. It was not only my family that was impressed, but the contractor was happy to be working with someone of his stature. If there were suggestions made by the contractor, T.J. was on site to discuss the ideas. We have absolutely no reservations regarding his work or service and highly recommend him.

The design work was wonderful and I would use them again in a second. Extremely impressively, they managed to double the usage of my home in square footage without changing the structure of the house. The way in which they kept the original Tudor style and changed only the roof line was fantastic.

Our house is a fixer upper, we knew that we would need to do a lot of work on it. We interviewed a few architects (one was pushing hard to completely demolish it, another was just trying to beautify what we already had, etc). My co-worker recommended Hierarchy. When we met TJ, he really stood out. My wife immediately called him "man with the vision". He sketched a proposal (in the first meeting) and very clearly explained how his rough ideas will be the most cost effective way for us to get what we want. The net result is that TJ converted our split-level old house into a new traditional colonial. There is a perception that Hierarchy is more expensive than other architects in the neighbourhood. TJ , Susan and their entire team is worth every penny! However, this is still a mere perception. TJ comes up with ideas that are so much better than what you had in mind, that you just want to go with them. Some ideas require a bit more spending in the short term, but are big wins in, say, 5 years time (it is really an investment) Hierarchy is a very professional team. TJ has the vision, Susan (she is awesome!) is very practical and the two of them balance each other out quite well. Hierarchy is well respected by building inspectors, design review boards, architectural review boards, contractors. Manhasset is known for long cycles to get your plan and design approved, Hierarchy got our fairly large project approved in one pass (which is rare)! - Hierarchy is a one stop shop. They will take care of your every need. There is a lot of handholding that you get from them every step of they way - They are very accessible. TJ works long hours, if you need him, he will call you back the next day at the latest. There were a few times, when my builder was stuck, or building inspector had questions. Susan, would come on site the next morning, 8:00 am sharp - Hierarchy will keep you from making mistakes whether it is over-spending, or contractor, or your own silliness. They are always on the look out for cost saving opportunities, they really care - They will give you an advice on just about anything: what windows to pick, what insulation to use, do you need to waterproof, color of siding, thickness of the roof, relative pricing of subcontractors, recommendations. Overtime you build up a lot of trust with them. We are very happy with TJ, Susan and Hierarchy. I highly recommend them!
