Home Addition Services for Your Growing Family

Whether you’re looking to add a second story to your bungalow, bedroom, loft, bathroom, or in-law suite, you can count on Astaneh Construction to nagivate through the by-laws and develop concepts for you to expand either up or outwards. Our team collaborates closely with each client, ensuring a functional design for growing families.

Here are the home addition services we specialize in:

Second-Floor Addition: Adding a new storey includes a full gut and new roof installation. We install new trusses and new roofing materials, avoiding any gaps or leaks that typically occurs when old and new materials are mixed.
Bump-Out Addition: Bump-outs add square footage to an existing room and range from 2 to 15 feet. Bump-outs can create mud rooms, walk-in closets, bathroom expansions, and reading nooks.
Garage Addition: Attached garages are both convenient and useful. You can park your car inside, increase your storage, or use the space for woodworking and other hobbies.
Sunroom Addition: Combine the outdoors with the comfort of indoor living with a sunroom addition. Choose between three-season and four-season sunrooms, with the option to include heating and cooling amenities.
Dormer Addition: We convert attics from a storage area to a livable space. Dormers enhance the natural lighting and also provide more floor space for guest bedrooms, playrooms, or reading rooms.
Rear Extension: We recommend this for large families as it offers more square footage than a typical room addition. Rear extensions expand the main floor, basement, and second floor without altering your home’s layout or flow.
Kitchen Addition: We design your kitchen around the extra space you need, creating open kitchen concepts. Get additional space for an island, entertaining guests, and more. Let's improve the your kitchen design, flow and decrease clutter.
Bathroom Addition: We improve the comfort, convenience, and functionality of your daily living. Accommodate your needs with an acccessible bathroom, three-piece bathroom additions or indulge in luxury with an ensuite addition.
