NDNY is a full-service architecture and design practice based in New York City. We provide services for the design and construction of new buildings and renovation/additions to existing buildings. Our expertise lies in full scale renovations working through an initial feasibility analysis through design, obtaining all required approvals and construction.
We work closely with Engineers, Designers, Expediters, Special Inspectors and General Contractors to creatively articulate our client's vision and bring their ideas to life. Since our inception, our mission has been to deliver projects that embody the highest functional aspirations using all the technological tools at our disposal to generate solutions with the smallest environmental footprint.
NDNY is a technologically focused studio. We utilize building information modeling software and video gaming technology to create immersive experiences (through VR and AR) for our clients, so they feel comfortable about the design direction at each step of the process. We leverage technology to seamlessly transition from the early phase of scanning the existing conditions to developing a comprehensive set of drawings that can be accurately priced. Our goal is to ensure our projects are fully coordinated to reduce change orders and give our clients a high level of confidence in the design before any work begins on site.
Architecture for us extends beyond the traditional realms and into areas that are not usually part of an Architect's orbit. NDNY has collaborated across architecture, interior design, industrial design, product design, engineering and virtual disciplines. This has allowed us to influence and be influenced by others. Through our practice we strive to make architecture more accessible by generating bespoke solutions for an ever changing and challenging world.
Feasibility studies: We offer low cost initial consultations and reports to help you understand and determine the parameters for your project.
Design: Drawings and 3 dimensional views for space layout/planning and programming, selection of materials, finishes and fittings.
Virtual reality: Create a virtual model and 360 views so clients can walk through the space to understand the design and experience the space.
Permit Drawings: Prepare drawings to obtain permits from the Department of Buildings and other regulatory agencies.
Construction Drawings: Prepare drawings that show in detail the materials, systems and other requirements for construction of the Project.
Bidding & Negotiation: Assistance with finding a contractor/builder and analyzing/comparing bids.
Construction Administration: Make site visits to observe construction.
