Chestnut Grove Design Group, Inc.

Chestnut Grove Design Group is a Boston-based firm that combines luxury residential interior design and landscape architecture, so homeowners can plan the inside and outside of a house at the same time. Husband and wife Ryan and Christina Wikman merged their separate companies to create it. The firm specializes in classic American interiors and landscapes meant to last, drawing on New England charm and British design and favoring quality materials that reference history.

Ryan, the principal landscape designer, studied at the Stockbridge School of Agriculture and ran his own landscape company for ten years. Christina holds a bachelor’s degree in interior design, started in custom kitchens and opened her own residential design firm in 2009, working on projects from South End brownstones to suburban family homes. Services cover new construction and renovations, interior architecture, full furnishings and project management, with color and pattern adding a fresh take on tradition.
