Custom Mother-Daughter Living Spaces on Long Island

Mother-daughter extensions offer a way for families to live together while still maintaining privacy and independence. Whether you’re caring for an aging parent or planning ahead for a family member moving back home, these spaces create a practical solution for shared living.

At Dormer King, we design and build mother-daughter extensions, apartments, and additions tailored to your needs. Each project is planned around your home’s layout and the level of separation or connection you want between spaces.

We also handle the full process from design through permitting and construction, helping remove the stress and uncertainty that can come with adding this type of living arrangement. The goal is to create a space where your family can stay close, without sacrificing comfort or privacy.
