While we do not build homes ourselves, we work with a trusted network of contractors who can help you turn our plans into reality.

Our plans are tailored more towards those collaborating with professionals, like general contractors (GCs) or specialized builders. This approach ensures that the unique features and design intricacies of our buildings are executed to the highest standard.

DEN offers pre-designed house plans, affordable customizations, and advisory services for planning, materials sourcing, and construction. We also now offer prefab shell kits — a streamlined path that delivers your DEN design as a pre-engineered, panelized kit ready for on-site assembly.

Have questions? Chat with a DEN build advisor in real time through our online platform or drop us a line at (845)-347-4987 or support@denoutdoors.com. We'd love to hop into a meeting to discuss your project, though we can usually get back to you fastest via email or chat. We're here to help however works best for you!

Absolutely! Over one hundred DEN homes have been built around the country. Many of these structures are privately-owned; however, some are available for short term rental through Airbnb. See if there's a DEN available for rent near you here.

DEN started in the Hudson Valley region of New York. Today, the DEN teams live throughout the US.

Once you purchase a DEN Building Package, you'll have access to our integrated online platform.

DEN is broadly available in the lower 48 states. We have had successful builds in almost every single state in the US. We are currently awaiting confirmation of the first projects in Alaska and Hawaii. Many customers in Canada have localized DEN designs to Canadian building code.

Every jurisdiction has unique requirements, so final plan stamping must be completed by a local architect or engineer with expertise in your area. DEN plans are created to provide a strong foundation for that process, making it easier for your local professional to secure a stamp. If you’re a Plans and Platform customer, engineering is completed by a local engineer with expertise in your region. However, if you’re a Prefab customer, DEN provides engineering for the entire structure and the standard of the plans, ensuring that your package is ready for permitting and construction.

DEN's plans and customization services are designed for individuals who have purchased land and secured capital to begin developing that property. Some of our customers have purchased plans before buying land to envision the scope of their project or to imagine what it is that they want to build, but generally speaking, it is helpful to have a specific site in mind, and financing in place prior to engaging DEN to provide preconstruction services.
