Space
planning is one of the most important aspects of interior design.
It can have a very strong impact on the success of a room. Without
proper planning, a room can end up awkward at best or disastrous
at worst. Knowledge of furniture sizes and space allowances,
some imagination and a sense of composition really help too.
In a well-planned room space is used to its utmost effect. The
room's needs and functions are taken into consideration, and
any difficult spaces or problem areas are dealt with. Your goal
is to accomplish this beautifully, comfortably, tastefully,
and so gracefully that the placement of all the objects in the
room seems both obvious and surprising.
A
scaled floor plan is like a map - it shows where you're
going and how to get there. With a good floor plan, you'll
know the right sizes of furniture to purchase, and where to
put any existing pieces that you already have. You'll
know how to place the furniture for maximum usage and comfort
with a pleasing sense of order.
So
how do you create this masterpiece of space usage? If you want
to do it yourself, there are some basic bits of information
that will help you on your way. You'll need to know average
sizes of furniture, human scale, and space allowances - such
as the right amount of space for walkways and movement of dining
chairs. Then you must decide what furniture goes into this room,
and the appropriate scale and proportion of the furnishings.
Think It Through
Before
you can begin with the tangibles, your first challenge will
be to think through your own needs, wants and ideas for the
room, as well as how you will be using it. Ask yourself these
questions to start:
Once
you've gathered your thoughts, you can start on the actual
plan. Make a list of everything you'd ideally want in
this room. Measure all the furniture you have already that's
going to be used here. Decide what else is needed to fulfill
your desired functions. Use the following guide for general
furniture sizes. Then start playing on paper. It's much
easier to draw or move around pieces of paper than large pieces
of furniture - it's almost like a jigsaw puzzle.
Drawing Your Plan
A
floor plan is like a map of your room. Think of yourself as
floating on the ceiling looking down on your room. You'll
see everything from the top only - two dimensionally (width
and depth), with no height shown. The point is to fit everything
you want and need into the space with the proper room left over.
And remember to make it flow well and look great too!
If
you haven't done this before, the easiest way to draw
a floor plan is to use grid paper. You can purchase paper that
has been printed with intersecting lines creating 1/4"
squares at an art supply or office supply store. Each 1/4"
square will represent one square foot. This is called quarter-inch
scale and is noted 1/4" = 1'. It's the most common
scale used for floor plans.
First,
draw the room dimensions, dividing the number of feet into the
correct number of grids. For example, a simple rectangular room
12' x 15' will be shown as a box 12 squares wide by 15 squares
long. You will also need to show doorways, windows, and anything
else that will need to be taken into consideration. You may
want to make several copies of your plan so that you can work
freely and create different options.
Your
next step is to put furniture into your room. One way is to
draw the furniture directly onto the plan, just as you did the
room itself. For example, a sofa 3' deep by 7' long (a pretty
typical size), will be a rectangle 3 boxes by 7 boxes. Or, if
you want to play around a bit more, cut out pieces from another
piece of grid paper representing the size of the furniture (you
may want to mark these pieces with the name of the piece of
furniture so you can keep track of everything).
You
can then easily rearrange all the little pieces of paper furniture
and see how the room could look with different configurations.
Think about how you'd like to use the room, where you'd
like to sit, or where the bed will fit the best, or how well
the dining table fits in the center of the room, and all the
other uses of the space. When you find a plan you like, you
can trace these pieces or tape or glue them on in place. Remember
that even though you're not drawing in the third dimension
(height), it still must be accounted for. For instance, you're
not going to want to put a tall cabinet in front of a window.
Another
way of drawing floor plans is to use a software program to create
the space. Usually these programs include some furniture sizes
and also can show elevations and 3-D renderings of the room
to give you a general idea of what the space will look like.
If the program you're using doesn't have the sizes of the furniture
that you want to use, you can leave space in the plan and draw
the needed pieces in by hand after you've printed your computer
plan.
Here
is an example of a room plan without furniture, and then the same
room with all the furniture drawn in. The size of existing furniture
was considered, plus the usages of the space and the human dimensions
that make conversation areas work well. When you're making your
own drawings, don't worry if your plan doesn't look like an architect
drew it - just make sure that the dimensions are accurate. If
it works properly on paper and everything is drawn to scale, the
room will work well in real life.
Furniture
Sizes and Space Allowances
Furniture
and people come in a range of sizes, but not that much of a
range. Furniture is made in similar sizes by every manufacturer,
because these are the sizes that are comfortable to people and
the sizes that we're all used to. For instance, you'll
notice that when you sit at any dining table, it feels about
the same height as any other, and it doesn't matter how
tall you are. However, you'll still want the scale and
proportion of the furniture to fit both you and the room -
within reason. You may move to another home later and will want
your furniture to fit properly there too. And sometimes, averages
must be thrown out the window, as in the case of a very tall
family who wants extra high cabinets in the kitchen (however,
don't forget about re-sale issues!). But, in general,
there are size averages to work with and you can figure these
averages into any plan. If you need a very particular size for
a difficult space, custom furniture is always a viable option.
There
are a lot of variations in furniture sizes, but it helps to
have some basic ideas when planning things. Here are some very
general size ranges of furniture, all shown in inches:

A Final Word
After
all this work to create a floor plan, you've just completed
the first step in designing your room. Once everything is planned
to scale and proportion, what follows is selecting and coordinating
all the furnishings that make an interior come alive -
the right furniture, flooring or rugs, colors, fabrics, patterns
and textures, window and wall treatments, accessories, art,
and the many finishing touches. You can have fun doing it all
yourself. Or, if you're one of the many people who don't
have the time, energy, or creativity yourself to put everything
together - and yet you appreciate beautiful interiors
- consider hiring a professional interior designer to
help.
