A significant portion of our work involves private residential landscape design, creating many master plans for new homes and/or renovation of existing gardens. These commissions include a range of project types from large estates to subdivision homes, summer cottages, townhouses and condominiums.

Each site is carefully and uniquely designed based on the clients’ anticipated outcome and total budget investment. Residential properties undergo preliminary landscape concept development with client input, budget analysis, detailed construction working drawings and specifications, along with co-ordination of landscape contracting services including project construction inspection and administration, based on client expectations.

Daniel J. O’Brien and Associates have an extensive portfolio of completed works that include all aspects of landscape construction from unique water features, custom designed swimming pools and spas to summer houses, loggias, hard surface stone work, custom masonry, artistic metal works, traditional and contemporary planting plans and night lighting special effects.
