We are so glad we took the advice as Christa was a much needed organizer, advocate and voice of sanity as we combined apartments in our renovation. She not only provided the standard architect plans etc but was also willing to answer artistic design questions and allay our fears during the seven month process. She recommended a good contractor and was usually quick to respond to our various issues. We definitely recommend! **★★★★★ — Kfir Klausner, Oct. 2018** > I worked with Christa on a ground-up rental project in Brooklyn. She was very helpful in both finding finishes within my budget, as well always being a resource for me as I navigated the thicket of finishing my first big project. I highly recommend her. > > Kfir **★★★★★ — Sarah Gerstenzang, Jan. 2018** > Christa helped us with the renovation of a one bedroom apartment for my mother. She also was the architect for our own apartment which involved the gut renovation of a dilapidated building and the carving out of five new apartments. Christa has an incredible sense of space and proportion as well as an ability to balance the old and new. She is also very practical, professional and responsive. Unlike some architects she really listens to what you want and need but also pushes back firmly if you head down a mistaken path with an idea. I wish I had another project so I could work with her again! **Comment from Horrigan O'Malley Architects:** > Thanks so much Sarah. You are a pleasure to work with! **★★★★★ — Sophia Schwartz, Nov. 2017** > We hired Horrigan O'Malley Architects on the basis of recommendations from previous clients who have worked with them. We found them to be professional and extremely gracious with their time. They understood our needs and demonstrated a willingness to work around them without sacrificing their own aesthetic sense. We especially appreciated the fact that they never tried to do an "up-sell" but instead gave us a number of options so that we could make an informed choice. Their response time was quick and our calls and/or emails were always returned promptly. I would highly recommend them and more importantly, happily work with them again. **Comment from Horrigan O'Malley Architects:** > Sophia, It was a pleasure working with you and I appreciate your comments. **★★★★★ — Libby Ryan, Sept. 2017** > Christa is the ultimate professional who also lives in the real world. She has her finger on the pulse of all the latest architectural designs and options and is very well-versed in adapting last century's buildings to today's life style. In fact, one of her great attributes is that she is comfortable with the city's permit process as well as the process of working successfully in landmarked districts. > But she also lives in a Brooklyn townhouse with a family and so understands the practical necessities of life. With Christa you will get the best of all worlds. I recommend her highly . **Comment from Horrigan O'Malley Architects:** > Thank you for the 5 stars, it is always a pleasure working with you. **★★★★★ — Anthony Rivera, Sept. 2017** > Always a pleasure to work with. Very knowledgable of the NYC code and zoning regulations. Horrigan O'Malley Architects are very professional and their response time is amazing. You will always deal directly with a partner on every project. Highly recommended!! **★★★★★ — Nancie Ludwig, May 2017** > I interviewed a total of 3 architects for a two story home addition. Christa was the only architect that listened and executed a drawing of my vision. She helped me realize my dream home with the most efficient use of space and modern conveniences. She provided me with detailed descriptions and drawings for my contractors and subcontractors. There was not one detail that wasn't addressed and the project completed beautifully and timely. Communication is so important and I always felt we were on the same page. Christa was available during the project when we needed her and well worth her fee. I would definitely use her services again and recommend her for any job large or small for a quality product. > N.Ludwig **Comment from Horrigan O'Malley Architects:** > Nancie, It was a pleasure working with you on both of your renovation projects! Best, Christa **★★★★★ — Nadean Finke, April 2017** > Christa is an extremely professional architect and someone enjoyable to work with. She listens to what you want and executes efficiently on your list. She stays within your budget and doesn't add frivolous costs. We would definitely use her again - we recently hired her to redesign the bottom floor of our townhouse that was a separate apartment and combined it with the rest of the house. Thanks again, Christa, for the great work! **Comment from Horrigan O'Malley Architects:** > Thank you Nadean. It was a pleasure working with you and would love to help you in the future! **★★★★★ — Philip Maguire, April 2017** > I worked with Horrigan O'Malley on 2 renovation projects- first our weekend home and then our apartment combination. Both projects came out great. Christa is easy to work with, is very considerate of client input and generates many creative solutions. I am very happy to recommend Horrigan O'Malley and just wish I had another renovation project coming up! **Comment from Horrigan O'Malley Architects:** > Phil, I was a pleasure working with on your Manhattan apartment and your country house! **★★★★★ — Tobey Diller, April 2017** > We cannot recommend Horrigan O’Malley enough. They were highly professional and entirely considerate of our family’s practical and style preferences. Proving both complete architectural and design services, as well as adhering to all government and co-op board permitting prerequisites, Horrigan O’Malley created a stunning, well-conceived apartment on time and on budget. **Comment from Horrigan O'Malley Architects:** > Tobey, I really enjoyed working with you, enjoy your beautiful apartment! ## Selected projects - [Prospect Park West Apartment, Park Slope, Brooklyn NY](https://www.houzz.com/hznb/projects/prospect-park-west-apartment-park-slope-brooklyn-ny-pj-vj~42198) - Location: Brooklyn, NY - Photos: 11 - Description: This landmarked limestone mansion was built in 1884 and originally designed by architect Axel Hedman as a single family home.

The design objective was to integrate the new building into the n… - [Park Slope Kitchen Renovation](https://www.houzz.com/hznb/projects/park-slope-kitchen-renovation-pj-vj~2872467) - Location: Brooklyn, NY - Photos: 2 - Description: This transitional kitchen brings a modern flair to this 1890's Romanesque Revival Townhouse.

Apartment combinations should feel as if they’ve always been one coherent layout. Given the limitations of 1950's high rises, this can be complicated. There are existing chases, risers, and columns, and coop rules against wet spaces over dry. Originally, this apartment was a series of small rooms and smaller hallways. By merging… - [Maine Family Retreat](https://www.houzz.com/hznb/projects/maine-family-retreat-pj-vj~2106259) - Location: Georgetown, ME - Photos: 43 - Description: This dramatic site sits high above the Kennebec River and provides unparalleled views.
