        "text": "A typical home addition project can take anywhere from three to seven months once construction starts, depending on scale and complexity. The preliminary phase—which includes architectural drafting, structural engineering, and municipal permit processing—often takes an additional four to eight weeks before physical work begins. Once breaking ground, phases include foundation excavation and slab pouring, structural framing, exterior roofing and sheathing, rough mechanical installations (plumbing, electrical, HVAC), insulation, drywall finishing, and final trim. Poor weather, delayed permit approvals, or custom interior material orders can lengthen this overall schedule.",
