Don't just take our word for it
See what our past clients have to say. 

Hi T.J. I hope all is well. I checked out the magazine and it’s a great piece! I remember that house from your Christmas party and I really loved it. I always appreciate those special elements you create when working with space. Lots of people can make rooms look great, but not everyone has the vision to create something special and unexpected that surprises out of existing space.

We work with Hierarchy Architects frequently. Not only do we enjoy their easy-to-work with manner, but our clients do as well. TJ Costello is an honest, friendly gentleman who brings a unique brand of intelligence to every project. TJ's approach to a job is always multi-faceted, seeing not one, but several solutions to the renovation. In the end, his work is seamless to the environment; an outcome that always exceeds expectations. When Hierarchy is on the job, you can rest assured that their years of know-how and soup to nuts oversight will be instrumental to the getting job done right the first time.

There are many reasons that Hierarchy is considered to be Manhasset's premier architectural firm. The depth of knowledge that TJ Costello and his entire team bring to a project is extraordinary. Their easygoing professionalism makes them easy to work with and responsive to all questions, suggestions and needs. They designed a new portico and a second story addition for our home. Both look as if they always been here, which we believe to be the ultimate sign of a successful renovation. What is most impressive about TJ is his attention to detail. For example, he was driving by our house one day when shutters were being installed. He stopped his car and instructed the workers to move the "S" hooks on the shutters over about an inch or so. This is just one instance of his eye for particulars and level of commitment that made our project a success. We highly recommend Hierarchy.

I am freshly off a one year, major renovation of my 1930 Farmhouse...I met with four architects and chose Hierarchy because they suggested they would design for me a version of what I wanted in a form that I could afford, that could be built in a timely basis, and would be "exactly" what I wanted, only better! I have learned over this time that being a good architect demands a long list of skills and talents that are not so obvious before hiring one...an architect must listen carefully and understand what you want, and bring to you multiple designs, and ideas that capture what you want in a version that is so much better, more elegant, more sophisticated, and in a better form of design and engineering then you ever imagined...like having someone interpret your dreams for your home in to a functional, affordable form that can be executed on site by others. That's what TJ Costello does. And he makes it fun...you end up loving the process. Remember, your architect isn't swinging a hammer, so his drawings and plans have to be clear, and perfectly drawn. The plans Hierarchy drew were literally perfect....down to every electrical plug, light, wire, wall, stud, and especially structural elements. Every tradesmen examined the plans without question and every town and village official approved all plans (and changes) immediately. The Hierarchy staff (especially TJ Costello) are imaginative and creative and can see solutions where there is not obviously one...TJ has ideas for everything that comes up, and is so generous to offer them, no matter how small, or complicated...and I had lots of both! We had so many issues that we had to seek his consult (and his excellent staff) I can't even recall...He was always available by some form (e.g. phone, email, text, etc) ...so you never felt that there wasn't a "source" to go to with a question. When I talked about lighting fixtures he gave me his personal ,architects version of a massive catalog where we ended up buying all our fixtures...when we complained about a vendor's performance he called them on my behalf and got them on track...he really is like your smart, creative best friend, that you can call and visit and get just the perfect solution...he has great taste, and excellent style...and offers all this to you as a client. He and his staff are really " Yes " people. They just get things done. And his fee? Okay...maybe not the cheapest, but very fair, and once your are a client, you have the perfect partner to share every concern, question and even celebrations. He and his staff are as happy for us now that the job is done, as we are. Look....there are lots of architects you can hire...but for the creativity, imagination, "easy-to-work-with" attitude, accessibility intelligence, ....there is no other firm you can a better result from then Hierarchy.

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.

You certainly receive the best of service in all aspects when dealing with this firm. They are extremely detail oriented and offer the best quality in product and workmanship. The customer service will go above and beyond to ensure satisfaction.

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!
