If there’s one thing that lays the foundation for an interior designer’s role, it’s space planning. Color, furniture, and accessories don’t happen unless the space is planned. Space planning is crucial for creating a functional, comfortable, efficient, and balanced space. It integrates activity, furniture, and circulation into a single space. It’s not that hard to imagine an aesthetically gorgeous interior, but it not being functional or practical.
The principles of space planning can help both professionals and DIYers design functional spaces that will endure for years to come. Instead of designing based on intuition alone, it offers a tried-and-true approach to space planning.
Understanding Space Planning
Space planning refers to the planning of a layout of an interior space to maximize its use of space with the required activities in the space, such as furniture layout, equipment placement, and special requirements. It also refers to the layout of a structure, room, building, office, building complex, etc.
It isn’t just about putting things in a room. It’s about creating relationships. A chair doesn’t go somewhere arbitrarily. It’s in relation to a table. To a light. To a path. To a view. It all affects the way a room lives.
In good space planning, there are three questions that are always answered: what happens in this space, how do people travel through this space, and what has to always be accessible.
Before any design work can begin, you need to get a read on the room. Like the title says, this is all about reading the room.
Prior to the sketching of any plan, a layout requires the consideration of any physical and functional limitations present in the space. This involves the measurement of dimensions, and documentation of any permanent features, and determination of space priorities.
First, write down:
Measure and record the following: Room width, length and ceiling height Window and door locations Radiators, columns, built-ins or other obstructions Electrical outlets and lighting locations Natural light direction
These constraints define the boundary of the design. You can’t design without them, or you will create a fantasy design. A designer should play within the constraints rather than in spite of them.
Also determine the main use of the room. A living room for entertaining requires a different configuration than one for movie nights. Function dictates location.
Principles of Zoning
Zoning breaks a room down into its functions. Don’t assume that just because you’re working with a small room you can’t define multiple zones. Zoning aids in clarity and helps prevent layout conflicts.
Common areas where this can be found:
Space zones Conversation areas Work areas Dining areas Relaxation areas Storage areas
Walls aren’t the only way to create zones. You can use furniture, an area rug, different lighting, or different directions that furniture faces. If you have a sofa and two chairs facing each other, you’ve created a conversation area.
A big rule is that each zone should be able to perform its function, without interfering with the other. Overlapped activities cause conflict and unease.
Flow and Trajectory of Traffic
Traffic flow: This is how people will travel around the space. A well-designed floor plan acknowledges pathways and leaves them clear. Bad traffic flow means you’ll be forever altering your course, bumping into things, or circumnavigating them.
Main paths should be simple and straightforward. A good rule of thumb:
Circulation paths should have enough space to easily pass
Doors should swing clear of furniture
Often-used pathways should not cross work areas
Motion should be natural. If a person has to dodge and weave to get into the room, then something is wrong. I think of flow as a little voice that shows you where to go without even realizing it.
Getting the scale and proportion of furniture correct is crucial in making a space feel cozy and inviting.
Think of scale as how the pieces of furniture appear in comparison to the space itself, while proportion is about how the different pieces of furniture compare to each other. Both are important elements of space planning.
When a room contains furniture that is too large for it, the space feels confining. When a room contains furniture that is too small for it, the space feels incomplete. But when a room contains furniture that is in scale with it, the space feels just right.
One strategy is to start with the most substantial functional element, whether it’s a sofa, a bed or a table, and design around it with other pieces of a similar visual scale.
Make sure to leave enough space between big objects. Overcrowding will make things less accessible, harder to read, and will simply look bad.
Distance of Clearance and Comfort
Comfort distances refer to the minimum distance required for usability. Failure to take comfort distances into account will result in a great design on paper that won’t work when you are done.
Key examples of clearances include:
Allowance for pulling back a chair
Clear paths around beds
Swing space for doors and cupboards
Clear space in front of counters
These dimensions are not hard and fast but rather practical recommendations. They allow the furniture pieces to be used without needing to be moved constantly.
Always visualize the physical movement that needs to occur — sitting, opening, walking, turning — and plan space for movement.
” Visual Anchors and Centers of Interest”
A focal point provides the eye with a resting point. It serves as an anchor for the space, providing direction for the furniture placement. A space without a focal point lacks direction.
These can include:
- A large window
- A fireplace
- A feature wall
- A statement furniture piece
- A media unit
Place key seating or activity furniture pieces to relate to the focal point. This makes visual sense. Too many focal points make a space confusing.
Use a single dominant anchor, and reinforce it with secondary anchors.
Open Plan vs Defined Layouts
This is where open-plan spaces differ from other layouts: there are fewer demarcations. Where walls once marked different zones, now layout, light and materiality take their place.
When the layout is open:
Use rugs to demarcate spaces – Use different layers of lighting to demarcate areas – Use the back of furniture to demarcate areas – Be mindful of lines of sight
In a room-by-room layout, the organization is easier, but circulation spaces and furniture positioning become more critical.
There is nothing inherently superior in either — different techniques are needed for each.
Flexibility and Multi-Purpose Planning
Versatility is a must in today’s interiors. If you have a small home, it’s likely that one room will have to serve multiple purposes. With that in mind, think about the ways you might repurpose the space in the future.
Examples include:
For example: A dining table that also functions as a workspace A sofa bed for guests A folding table and chairs, or a nesting table A room divider or screen
What makes planning for flexibility successful is that secondary use doesn’t interfere with the primary use. A home office in a living room doesn’t mean it should be positioned where it interrupts the flow of the room. In designing for multiple purposes, think harmony, not over crowding.
Mistakes to Avoid When Planning Your Space
A lot of design flaws are caused by common errors. Being aware of them saves you from having to redesign.
Here is the list of common decorating mistakes: Placing all furniture against walls regardless of room size Blocking the natural traffic pattern Not accounting for the door swing Not using the right scale furniture Too many mini spaces in a small space Not planning for task lighting
Another mistake is designing from a plan only without envisioning the space in use. You need to mentally inhabit a design in three dimensions.
Testing and Refining Your Layout
A good designer will always lay out their designs. This can be with scaled drawings, or with online planners, or with pieces of floor tape on the floor.
The practical questions are:
Can 2 people walk through this space comfortably?
Can I use this piece of furniture without having to move other things around?
Can I clearly use each defined space?
Does this space look balanced when I look in from the door?
Revisions are to be expected. Space planning is a process, not a single event.
