Welcome to a truly exceptional offering in St. Margarets Landing! Prime location meets turn-key design on a coveted corner lot, strategically hand-selected by the original owner for its sunlit openness, minimal pass-through traffic, and immediate gate access to neighborhood walking paths. Inside, real hardwood flooring spans the main level, upper level hallway, and all staircases. Spanning 6 total bedrooms and 4.1 baths, the flexible layout is designed for modern multi-generational living with two Primary Suite options -including a main-level primary featuring soaring vaulted ceilings, and an upper-level primary suite alongside 3 additional spacious bedrooms. NOTE FOR SHOWINGS: Tax records incorrectly reflect the finished lower-level square footage; the basement actually features an expansive 900 sq. ft. in-law / multi-generational suite with an outside private entrance, designed for complete flexibility, along with two massive dedicated storage areas (see floor plans in photos). The lovely main level flows seamlessly through a formal living room, great room with stone gas fireplace, breakfast area, large kitchen with plenty of counter space, formal dining area, laundry room, and garage entrance. Dual sliding glass doors off of the breakfast area lead to your outdoor retreat: a generous back deck and paver patio overlooking a fully vinyl-fenced backyard wrapped in mature, privacy-enhancing arborvitae trees and served by a 9-station irrigation system. Peace of mind is built right in, anchored by a roof replaced within the last five years and a full-home Generac backup generator that kicks on automatically in 30 seconds. Located in the top-rated Broadneck School District, 605 Lighthouse Landing also affords rapid access to premier private education including St. John the Evangelist, Severn School, The Key School, Indian Creek, and the U.S. Naval Academy. An ideal commuter hub close to major employers like Fort Meade, NSA Headquarters, defense tech corridors (Lockheed Martin, Northrop Grumman, Booz Allen), Luminis Health Anne Arundel Medical Center, and downtown Annapolis.
