The most common mistake is prioritizing room size over room placement and flow between spaces. Putting a laundry room far from bedrooms, isolating the kitchen from family gathering areas, or designing hallways that waste square footage are all layout errors that affect daily life. Ignoring natural light patterns and placing living spaces on the wrong side of the home is another frequent oversight. As of September 2024, homeowners who skip professional space planning often discover functional problems only after construction is complete, when fixes become expensive. Kingdom and Co. uses detailed floor plan analysis and 3D modeling during the design phase to identify and resolve layout issues before any walls are built or moved.
