Our Clients


JP Donohue and his staff are extremely professional, dedicated and proficient.  Our thoughts and needs, as well as a wish list were considered and included in the drawings. It was amazing to see what an older property's potential could be!  I highly recommend JP Donohue and Studio 111 and look forward to working with them in the future!

Studio 111 designed plans for our city roof deck. JP conveniently met us in our home and was always punctual as well as professional.  His architectural plans were completed before each deadline, neatly and with detail. JP discussed the plans with us, and modified the plans accordingly. He attended any zoning meetings that were necessary and coached us through the planning process of building a roof deck in Philadelphia. JP also met with the contractors before and during the building process. We had a wonderful experience working with Studio 111, and are thoroughly enjoying our finished product.

“We engaged Studio 111 for an end-to-end kitchen remodeling, from design services through every phase of construction. We immediately felt comfortable with JP and his team, as they seemed to quickly understand our objectives for the project as well as our design sensibility -- something we have found is an absolute necessity for this type of project.  Our confidence was well founded, as the Studio 111 team delivered our completed kitchen -- which we love -- on time and on budget.  We would use them again in a heartbeat

What differentiates JP and his team from the others we have worked with is their absolute professionalism, which extends from reliability (always showing up on time when they were scheduled) to work quality, to clear and frequent communication of status. Further, on many occasions JP went above and beyond -- making this complex project run much more smoothly than we might have imagined.  I would recommend Studio 111 to anyone -- in fact we already have with several friends and neighbors.”

They did a complete renovation of the first floor of a historical building in the center of Philadelphia. It is now a Juice Bar. They were with of us every step of the way from architectural design to building codes to health department to construction. They were responsive to our needs and made the whole process feel like we were a team. Everything went well. When there were problems, they consulted with us and never moved forward without our permission.

I met with Studio 111 to discuss some prospects for new construction, specifically I was interested in building on a lot in the Graduate Hospital area of Philadelphia. My first impression was that they were punctual and cordial. We spoke for over an hour, discussing layouts, variances, neighborhood organizations, garages and other matters pertaining to the difficulties of building on the particular lot I referenced.  They seemed well-versed with the process.  Prior to our meeting, they had obtained an estimate for tying into the city's water and sewage lines, something that I had not asked them to do. This information was particularly helpful. I found their rough construction estimate to be a fair estimate.  A couple days later, I received an email that made it clear they had given serious consideration to some of the ideas we discussed at the meeting.  Ultimately, the limitations of the lot proved to be the death knell for any new construction plans. I will definitely use Studio 111 when I find another lot to build on.

Studio 111 expressed compassion and understanding about issues that were specific to our family and worked patiently with us.  Their professionalism and willingness to answer all of my (endless!) questions allowed my husband and I to arrive at the decision that was right for our home and our family.  As a result, their company did not end up benefiting financially; however, the most attractive aspect of this company for me was the humanity with which they approached our situation and our needs (a rare find.)  This team of designers struck us as extremely talented and if the occasion arose where we needed anything built or added on to our home I would absolutely call them or recommend them to a friend.

Great experience overall. Working with Studio 111 was a great experience from start to finish. Their work looks fantastic, they were professional and punctual. They are truly a first-class operation. Working with JP was a pleasure. He is smart, professional and really knows his stuff. I would highly recommend them and would work with them again if the need arises.
