Start by choosing the main purpose of the space: outdoor meals, a quiet sitting area or a connection between the house and garden. In a compact yard, mark the table and chair positions before choosing the deck outline; leave practical routes to doors, side gates and planting. For a larger property, consider whether a smaller shaded area would be more useful than one broad exposed platform. If your South Bay site slopes, include photos showing the ground beneath the proposed deck and the route from the street. We have hillside deck experience, but the foundation and framing approach depends on your actual site. A replacement also starts with checking existing posts, beams, joists and connections before choosing which parts can remain. For a pergola, describe where you want shade and at what time of day. Our existing San Jose, Los Gatos, Cupertino and Santa Clara deck pages offer additional starting points. Send your city, approximate dimensions, photos and preferred materials so we can discuss a practical scope and estimate.
