Ground-Floor Expansion Design

My ground floor needs to grow. I want a cohesive exterior and interior concept that lets me push the external envelope outward so the living room, kitchen, and bedroom each gain practical square footage without feeling like bolt-on additions. The priority is pure additional space; visual polish and smarter flow come second, but still matter.

Here is what I expect to receive:
• A set of scaled layout drawings showing how the new footprint integrates with the existing structure.
• Elevations and 3D perspective that illustrate materials, rooflines, and window placements so I can picture the finished look from outside.
• Construction-ready dimensions and notes in DWG or PDF, suitable for a local architect or builder to finalize.

AutoCAD, Revit, SketchUp, or similar tools are all fine so long as the files are fully editable. Accuracy, clear labeling, and a layout that genuinely adds usable space to the living room, kitchen, and bedroom will be the acceptance criteria.
