A Simple 8-Step Space Planning System
Learn how to master space planning with my simple 8-step system. Create functional, beautiful interiors that feel effortless, natural, and well-planned.
When it comes to creating functional, beautiful spaces, great design starts long before choosing paint colors and furniture. It begins with smart space planning. The blueprint for a project's success. Whether you're designing a home, office, or commercial environment, a well-thought-out space plan will ensure the layout feels thoughtful, practical, and effortless.
1. Develop the Space Program
Before taking a single measurement, it's essential to understand the people and purposes the space must serve.
-Identify the function of the room.
-Define project goals, design direction, and any special space requirements.
-Always factor in building codes and accessibility requirements.
Tip: Use storytelling to guide your space planning. Think about the feeling, place, and imagery you want the environment to evoke. Developing a strong narrative anchors every design decision.
My most referenced books for space planning- Space Planning Basics, Time-Saver Standards for Interior Design and Space Planning and Human Dimension & Interior Space: A Source Book of Design Reference Standards.
2. Assess the Existing Space
A thorough site assessment lays the groundwork for an efficient and accurate space plan.
-Walk through space and capture detailed photographs.
-Sketch a rough floor plan layout.
-Measure room dimensions, door and window openings, plumbing locations, and other fixed elements.
Tip: Save time with both a laser measure and tape measure. I recommend sketching layouts in a compact graph notebook for easy scaling and quick reference.
3. Prioritize Plumbing-Heavy Areas
Plumbing often dictates immovable elements in a layout — and should be planned for early.
-Begin planning kitchens, bathrooms, and utility spaces around existing plumbing lines.
-Measure plumbing centerlines during your site walkthrough.
-Consider fixture selections early on to support layout decisions.
Tip: If replacing fixtures, explore water-efficient models to enhance sustainability goals.
4. Create a Dimensioned Space Plan (I use AutoCAD)
This is where your conceptual ideas turn into a structured, buildable plan.
-Develop a fully dimensioned floor plan, showing rooms, door swings, windows, and major built-in elements.
-Prioritize plumbing-dependent spaces first to avoid costly changes later.
-Map circulation paths to ensure smooth, intuitive movement.
Tip: Divide large or irregular rooms into zones to improve flow and functionality. Pay special attention to corners.
5. Plan Furniture Layouts
Once the space structure is clear, bring it to life by planning furniture placement.
-Arrange furniture in groupings (sofa + coffee table + side chair) to create cozy, functional zones.
-Center furniture around a natural or designed focal point, like artwork, lighting, or key architectural features.
-Ensure visual balance throughout the space.
Tip: Perform a Balance Test — mentally divide the room into four quadrants. Each section should have a harmonious mix of furnishings and breathing space.
6. Think About Lighting
Lighting has a dramatic impact on mood, functionality, and how large a space feels.
-Plan layered lighting: natural light, ambient lighting, task lighting, and accent lighting.
-Place fixtures strategically to avoid shadows and poorly lit areas.
-Ensure easy access to light switches and controls.
Tip: Always check door swings when planning lighting locations to avoid conflicts with sconces or pendant lights.
7. Design Considerations
Interior Design goes beyond furniture and finishes, the invisible details matter, too.
-Address acoustics and sound control from the beginning.
-Consider sustainable materials to support a healthier indoor environment.
-Create visual interest by playing with ceiling heights, soffits, and unique architectural features.
Reminder: Constraints aren’t setbacks. They’re opportunities to create something amazing..
8. Final Review and Refinement
Review and refine throughout the process.
-Step back and review your space plan critically.
-Make adjustments for flow, function, and comfort.
-Once finalized, you’re ready to move forward with full interior design development.
Final thoughts on the Space Planning Process
Effective space planning is the foundation of every beautiful space. By following a clear, proven system, you maximize function, enhance well-being, and create spaces that feel as good as they look.
Whether you're an architect, home owner, or interior designer, creating a thoughtful space plan will ensure every project starts strong and finishes even stronger.
