Home Addition Types We Build in Wheaton, MD
Single Room Addition
A new room built onto the side or rear of your existing home — bedroom, family room, or home office — fully integrated with the existing structure, roofline, and interior layout. Foundation, framing, roofing, electrical, HVAC, and all finishes included.
Second-Story Addition
Add a complete or partial second floor above your existing home — maximizing square footage without expanding the footprint. Requires full structural engineering to verify existing foundation and wall capacity. Adds the most square footage per dollar of lot used.
Master Suite Addition
A dedicated primary bedroom and bathroom addition — one of the most popular additions across Wheaton, MD. Typically includes spacious bedroom, walk-in closet, and luxury bathroom. Adds significant value in Wheaton, MD's active resale market.
Bump-Out Addition
A targeted 2–12 foot extension of an existing room — expanding a kitchen, widening a master bath, or creating a breakfast nook. Faster and more affordable than a full room addition. Often cantilevered or on a shallow foundation.
Family Room Addition
Expand living space with a dedicated family room or great room off the rear of your home — often combined with kitchen expansion. Vaulted ceilings, large windows, and open kitchen connection are the most popular design choices.
Four-Season Sunroom
A light-filled, fully conditioned addition with expansive windows designed for year-round use — perfect for rear yards with garden or wooded views. Full HVAC connection, insulated walls, and heated floors.
