Samuel Sinnott and Company, Architecture and Construction Incorporated, is a construction corporation providing full services in Residential and Commercial Interior Architecture, Interior Design, Site Design, and Construction. Services start with a free, onsite kickoff meeting to see if the project vision conforms with building codes, can be executed attractively, and can be delivered on budget and schedule. Service typically includes verification of existing site and building conditions, conceptual design, preliminary project cost estimating, permit documents, construction documents, and construction.
Conceptual drawings are often drawn by hand in ink to save time and have a more artistic outcome. Our preliminary construction and project cost estimating is a valuable design tool that helps avoid costly redesign if construction costs are over budget. Sinnott and Company incorporates permitting strategies that identify plan check problems in advance and streamline permit plan checking. These approaches help our unique and artistic projects meet construction budget and schedule expectations.
Design work is always performed on a time and material basis. Hourly rates are usually $180 per hour for principals and $120 per hour for all others. Reimbursable expenses are typically marked up by 15%. This approach allows us to work flexibly on whatever the client wants or the problem demands.
A construction agreement is not a requirement of the design agreement but is offered as part of our services under a separate contract. Clients have complete flexibility to choose any supplier or subcontractor to help deliver the project. Rates and markups vary with the scope and difficulty of the work.

TESTIMONIAL

WHAT OUR CLIENTS SAY

“We have relied on Sam as our architect for two houses of distinct styles, and have been delighted with his skill and aesthetic instincts. We trust him to create beautiful and livable spaces, that are also not “cookie cutter.” His construction crews are professional and expert, as well as being considerate people who communicate well. We continue to feel proud of our house and we credit Sinnott & Co for continued excellence.”
Wendy and Evan Ellis
Customer
“Sam does great work and has a keen eye for detail.  His team is thoughtful and attentive.  We love our new kitchen and would highly recommend Sinnott & Co. to anyone whose project requires an artistic touch.”
Jackie and Matt Perotti
Customer
Sam was amazing to work with, he covers all aspects of the process with a rare combination of business skill, practicality and impeccable design, but his greatest attribute is that he truly cares about every person that he works with, from the client, to his extraordinary staff and the vast network of contacts in the trades he has known for years.
John and Amy Park  
Customer
I have been finding the locations for Pottery Barn catalog photo shoots for many years now and just came across Sam Sinnott's Houzz page and must say what a gracious man he is and how beautiful his work is.  We have several of his projects in our files for potential photo shoots and they are all beautiful and different.

Customer
I hired Sam to do a kitchen and bath remodel.  Though a little more expensive than some others, I had seen their work for two friends and decided to go with them. The quality of the work is top notch. A long remodel can be a trying experience and Sam's crew did their best to be respectful of our space.  Would probably hire again.
Frank Shaw
Customer
Listened to clients but not hesitant to disagree and provide his perspective. Good communication on all design and approval issues. Used imagination in critical design areas of this renovation. Would definitely recommend Sam Sinnott on the architectural design of any new or remodeling residential project.
Norm Harris
Customer
It was a pleasure working with Sam and his crew.  We felt that having the same company both "design and build" our kitchen/dining room/living room/laundry room/bathroom renovation project saved us money, and more importantly, time. They were all professional, considerate, easy to reach and always responded quickly to our questions.
B. Tom
Customer
Working with Sam on our garage conversion was fun and went smoothly even as Covid hit us right at the start. His communication was always prompt and clear, we were always kept informed of all issues. Sam really listened to what we wanted which is a huge plus and even accommodated changes late in the game. Moreover, his people were amazing craftsmen and wonderful humans who were very respectful of our space and time. We really enjoy the new space and are so happy with the results.                                         Meera & Ravi
