Before and After

We’re proud to be the leading company on Long Island, offering custom-designed modular homes & additions to the residential housing community. At East Coast Dormer we have developed and perfected an exciting revolutionary advancement in home improvement which turns the hectic 3 to 6 month (or more) inconvenience of a traditional “on-site-renovation” project… into a shorter, more pleasurable and less stressful experience. We achieve this goal by combining a flawless level of control with an unparalleled attitude towards your comfort and the saving of your precious time. East Coast Dormer’s in-house designers and draftsmen will provide you with architectural drawings for your new home or additions; all drawings are state and locally approved. Call us, let us show you and explain how we can custom develop a second floor or home extension… just for you and your family.

Modular building Systems

1. Initial Consultation Your journey begins with a personal consultation with our experienced Long Island sales and modular design team. This initial meeting is the foundation of your project, where we listen closely to understand your vision, preferences and specific needs. 2. Assessment & Qualification Phase We take the time to discuss the potential of your current home and how it can be transformed. Not every house is immediately suited for a second-floor addition or extension. We thoroughly assess your space for the proposed changes, considering structural integrity, zoning laws and other critical factors. 3. Design & Planning Once your home qualifies, our team drafts detailed plans for your modular project. This collaborative phase allows you to provide feedback and adjustments to ensure the final design perfectly captures your vision. 4. Contract Signing With your design finalized, we move forward by signing a contract. This formal agreement outlines the scope of work, project timeline, costs and other essential details, providing both parties clarity and peace of mind. 5. Manufacturing & Approval East Coast Dormer specializes in modular construction, where sections of your home are manufactured off-site in a controlled environment. This approach not only enhances quality but also reduces construction time. 6. Installation The modular unit sections are transported to your site and expertly installed. Our team ensures that every unit fits perfectly, transforming the structure into a cohesive and beautifully renewed home. 7. Completion The final step is the most rewarding—walking into your newly transformed home. Our team will ensure that everything meets your expectations and any finishing touches will be added as needed. Finally, you'll be able to enjoy your new home or newly expanded home to its fullest.
