We expanded our kitchen to the back, and raised the one-story side to two-story, making room for an additional bedroom and full bath. She initially developed 2 schematics, got them priced, and we worked out a combination to meet our budget. I knew I wanted to work with her when we first met, and she looked at our 1864 home and told me the plan would be to preserve its historic proportions. I recommend Dianne without hesitation. **★★★★★ — drvickiehrlich, April 2017** > Very comprehensive, creative and capable professionals! They are visionaries in that they think outside the box but are also detail oriented. Diane is a very talented architect who is also very personable! **★★★★★ — barbaraosborne, Sept. 2015** > Designed our dream house on the Sound in Rye. There command of architectural details is absolute precision and they really are able to listen to what their clients want and to deliver it in the most creative way possible. I wanted our home have elements of Arts and Crafts, Frank L. Wright and yet not be too stark. The firm is excellent with paying attention to detail and building a big house means many, many details. > > Highly recommend this firm for luxury homes........ **Comment from Keller/Eaton Architects:** > Thank you for the ringing endorsement. It is a pleasure to work with you! ## Selected projects - [Kitchen and Baths](https://www.houzz.com/hznb/projects/kitchen-and-baths-pj-vj~506917) - Location: Larchmont, NY - Photos: 35 - [Seaside Shingle Style](https://www.houzz.com/hznb/projects/seaside-shingle-style-pj-vj~2412068) - Location: Larchmont, NY - Photos: 8 - Description: This historic shingle style home was damaged during a hurricane and renovated beyond recognition by a previous owner.
