Modern Family House Expansion DWG with Detailed Home Addition Plans

This AutoCAD DWG file presents a complete family house expansion design featuring both the existing structure and the new modern home addition layouts. The drawings include full architectural plans with room extensions, modified interior layouts, updated circulation routes, and improved space utilization. The floor plans clearly distinguish the original construction from the added rooms, illustrating bedrooms, living spaces, kitchen areas, service zones, and enhanced access points. Elevation and sectional views highlight changes in building volume, roof alignment, stair placement, façade modifications, and construction detailing required for a smooth integration between the old and new areas.

The DWG file also includes electrical layouts with updated lighting circuits, power outlets, breaker panel diagrams, and load distribution charts adapted for the expansion. Plumbing plans display water supply extensions, drainage line modifications, sanitary routing, and fixture repositioning. The structural sheets show column adjustments, beam reinforcements, slab extensions, and foundation details to ensure safe and stable load transfer throughout the expanded design. Ideal for architects, civil engineers, builders, and interior designers, this family house expansion DWG provides a complete technical package that simplifies renovation planning and ensures efficient execution of home addition projects.
