About Haven ADUs
Haven ADUs is a design and project management firm based in Brooklyn, New York, focused on helping property owners plan, design, and build accessory dwelling units (ADUs). Their work spans a range of project types, from guest houses to backyard structures, with a process built around clear communication and coordinated project delivery.
The company positions itself as a single point of contact throughout the entire ADU development process — from initial feasibility through design, permitting, and construction. This approach is intended to reduce the complexity that property owners often face when navigating multiple contractors, designers, and local regulations on their own.
How the Process Works
Haven ADUs follows a structured, multi-phase process for each project:
- Free Consultation Call — An initial conversation where their team helps determine what is feasible on a given property. They discuss project timelines, budgets, and the client's design preferences.
- Preliminary Design — A designer is assigned based on the specifics of the project. They develop a design proposal tailored to the property and the client's needs.
- Detailed Design & Engineering — Clients work with their designer through online design reviews. A dedicated project manager oversees progress, and clients have access to a client portal with real-time updates. Once design is finalized, the team produces all drawings required for permitting and construction.
- Build Phase — Haven works with a network of vetted local contractors to gather construction cost estimates from two to three builders in the client's area. They walk builders through the project, schedule site visits, evaluate the bids, and recommend the most suitable contractor. Haven also provides construction administration throughout the build.
One notable aspect of their model is the localized bidding process. Rather than relying on a single contractor, Haven collects detailed bids from trusted local builders and recommends the best fit based on both expertise and the specifics of the offer. This gives clients a more informed basis for decision-making.
Expertise and Project Scope
Haven ADUs brings localized zoning and code expertise to each project, which is particularly relevant given how significantly ADU regulations can vary by municipality. Their featured work includes projects in areas such as South Orange, NJ, and Five Mile River, reflecting experience across different jurisdictions in the Northeast.
The company also offers a ready-to-build ADU collection — a set of pre-designed ADU plans that can help streamline the early stages of a project for clients who want a more defined starting point.
Haven ADUs is located at 348 Nostrand Avenue, Brooklyn, NY, and serves property owners looking to unlock the potential of their properties through thoughtfully designed accessory dwelling units, guest houses, and similar structures.
