By providing a steady stream of business to our key business partners, and developing relationships spanning 20-30 years, we are extended unparalleled courtesies.  This allows for the strongest buying power, follow-up service, collaborations and problem solving, as well as flexibility throughout the project allowing for changes, control of budgets and schedules. All vendors and tradespeople are expected to provide regionally competitive pricing.  Prices are checked regularly to insure competitiveness.

“A fair and equitable approach is applied to pricing and relationships.  We put a tremendous value on relationships, service, reliability and accountability.”  Chris Alvarez, Partner

We are not a remodeling company or a Jack-of-all trades.  All work is subcontracted to our vast and reliable source of experts.  We maintain a nearly unlimited stable of subcontractors and tradespeople.  Every aspect of the project is allocated to those best suited to complete the required task with the utmost professionalism and quality.


Douglas Slater

Doug Slater has spent the last 30 years in real estate development and construction.  He founded D.A.S. Associates, Ltd. in 1991.  Concurrently Doug pursued real estate development deals, focusing primarily on high end single family homes in Greenwich, Connecticut and the surrounding areas.

Christopher Alvarez

Chris graduated Adelphi University with a degree in Business Management.  He had an outstanding 4-year career on the Adelphi baseball team and was team captain for two of those years.  Chris Alvarez is a third-generation contractor.  Needless to say, construction runs deep in his veins.



Founding partner, Douglas Slater, has spent more than 30 years in real estate construction and development.  By 1993 Doug was concurrently pursuing real estate development deals while continuing to build the construction arm of his firm.  With a keen focus on high-end single-family homes and development, D.A.S was already building homes in excess of 10,000 sf by 1994. Joining the firm immediately out of college, Chris Alvarez brought his third generation contracting blood to D.A.S. becoming a key and invaluable employee, ultimately becoming a partner. Both partners still take an active and lead role in the day to day supervision and management of each project.  We feel every project is important and to this day Chris or Doug visit every site every day, most often together.

“This is an incredibly hands-on approach unique to D.A.S.  There is no reliance on less experienced or less committed personnel.  At least one partner visits each project every day”.  Chris Alvarez, Partner

By 2000 D.A.S. had become a highly regarded builder of homes and estates.  Having shifted their primary focus to building custom homes, D.A.S. has clearly solidified their niche within the high-end luxury home market

Both partners own keen eyes for detail and uncanny senses of quality.  Their deep understanding of the trades and construction process comes from having worked their own ways through all the trades.  Each partner possesses every skill required to complete every aspect of the construction process, hence their intimate and hands-on approaches to project management.  Each project is handled as it was their own.  Every project begins by vetting and assembling the necessary professionals from our team of experts.  Working closely with the client and design professionals, D.A.S. ensures that everything is done in compliance with the architects’ specifications, the clients desires and expectations, on time, and on budget.  Throughout the process, D.A.S. works side by side with our clients to help them achieve their visions and dreams.


My husband and I are very pleased with our beautiful custom home addition in Greenwich, CT built by DAS Builders and we highly recommend them! Choosing the right builder was very important because we wanted to live in the house during the construction with young children, elderly parents and pets. After an exhausting search and analysis of several builders, we selected DAS Builders based on the high quality of their homes, the craftsmanship, and attention to detail in the finishes. Most important, we had high confidence DAS would provide us with the value we were looking for. DAS worked hard with us to make it the least impactful to us as possible as we were living in the house during the whole construction. They made sure the job site was clean and safe for our family throughout the process. They kept everything running smoothly and on time throughout the project. All subs hired by DAS were solid people, people you wanted to have on your property, worked diligently and did great work. We need to complete this review by highlighting the exceptional quality and follow up DAS delivers. Our home looks like something out of a magazine. The craftsmanship, functionality, and beauty is beyond what we imagined. We are so happy that we made this investment into our home and would recommend DAS to anyone considering a renovation or new construction. The DAS team was a pleasure to work with.  [They] are highly skilled, trustworthy, and are very quick to respond to any questions or issues, even after the project is completed. We’re eager to work with DAS again in the future!
