I had heard someone once say that the irish basically built New York. After this project I can understand why. Fionan and his crew was incredibly efficient. We had 1 week to do an unthinkable amount of work, which included painting , gut renovations of certain areas, moving a large decorative Balinese door, demolition of interior walls, rewiring electric, laying hardwood floors, and epoxy paint coating the entire floor of the 5,000 SF space. Fionan was not only efficient, but organized. His team was on time, worked hard, and got the job done. Despite several setbacks that are bound to pop up in ANY job, Fionnans creative solutions to problems made moving through them effective and EASY!
You want the job done...let Fionan renovate or construct your piece of NY.

After six months of looking for contractors to handle the renovation of our new co-op unit (you'd be surprised how many folks just stop responding to calls and emails when they decide they can't or won't do the job), we lucked out and stumbled into Fionan during our final hour of despair. Always the consummate professional--Fionan completed our project on time and within budget, even with the omnipresent spectre of scope creep looming over the horizon. His communication is timely, his demeanor is respectful and charitable, and the quality of his and his team's work was exceptional. I'll be looking forward to the day when my wife and I have another project to undertake--so we have an excuse to work with San Nioclas Developments again. No joke.


Need a renovation - San Nioclas Developments is the way to go. Their team was very efficient, accommodating and professional and delivered a satisfactory product within a short time frame. We are very happy with the results.

Confirming & validating San Nioclas Developments as a client as well as a practicing interior architect, Fionan and his team (professionalism, quality, resources, on time delivery/construction) outdid a lot of my working contractors from the past as well as current ones when renovating my Brooklyn Town House

Fionan and team have been extremely helpful and professional in not only renovating my bathroom but also doing smaller tasks for my place like plastering the wall and the ceiling.
I am very happy with the outcome of both projects big and small.
I highly recommend Fionan and his team.
