Atlantic Heights Development

Atlantic Heights Development is a residential subdivision with over 120 houses in Portsmouth, New Hampshire, spread across approximately 80 acres and including several small parks and a school building. The neighborhood sits between Interstate 95, the Piscataqua River, and Boston and Maine Railroad tracks.

The neighborhood was built with American government funding during World War I to house workers at Atlantic Company Shipyard. Since its completion in 1920, it has stood as an example of how the government quickly provided housing for industrial workers.

The development displays seven different house designs by Kilham & Hopkins architects, showing how residential neighborhoods were planned and built in the early 1900s. Visitors can still see today how these different houses come together to form a cohesive community.

The neighborhood is easily accessible given its location between multiple transportation routes, which visitors should keep in mind when planning their route. The area is best explored on foot to see the different house styles and parks in their original setting.

Many of the original houses from 1920 remain intact today, showing the residential construction methods of that era. Interestingly, many of these homes later received added garages, reflecting how daily life changed with the automobile.
