Living Room Layout Preparation Checklist

Sketch the room roughly and mark every alcove, projection, bay and change in ceiling height, since these decide where anything tall or deep can sit.

Most living rooms have fewer usable walls than they appear to, and the sketch makes that obvious before furniture is chosen.

Note whether the walls look straight and the corners square, because furniture and fitted joinery meet walls that are rarely as true as a drawing suggests.

A run of joinery drawn to a perfect rectangle needs scribing to a real wall, and it helps to raise that early.

How a wall or floor should be prepared for fitted joinery is for the joiner and a qualified professional to advise on.

Mark where radiators, visible pipework and any vents sit, and treat every one of them as fixed until a qualified professional says otherwise.

Heating positions quietly rule out whole walls for seating and storage, and they are usually noticed after the layout is drawn.

Whether heating pipework or emitters can be moved in this room is a matter for a qualified heating professional.

Note the position of existing sockets, switches and any aerial or data point, since these quietly decide where a screen, a lamp or a desk can live.

Working with the points you already have is often the difference between a simple project and a disruptive one.

Record any change in floor level, threshold strip or access hatch, and note whether it falls in the part of the room where seating would go.

A hatch under a sofa or a threshold under a rug often becomes a permanent nuisance that was visible from the start.

Write down which way each door swings and how much of the room it sweeps, then note what could not stand anywhere inside that arc.

The swept arc is dead floor, and knowing its shape stops a piece of furniture being planned into it.

Note whether a door could be rehung to open the other way or changed to slide, and ask a qualified professional what that would involve here.

Changing a door swing sometimes releases the one corner that makes an arrangement work.

Altering a door, its frame or its opening is a matter for a qualified professional to assess before it is planned.

Consider which doors are left open almost all the time, because a door that lives open takes wall space rather than floor space.

An open door parked against a wall rules out that wall for a bookcase or a screen just as firmly as furniture would.

Note how the room connects to the hall, the stairs and any garden door, and which of those openings is genuinely used most.

The busiest opening sets the main route through the room, and everything else has to arrange itself around it.

Ask a qualified professional what should be kept clear around the doors and openings in a room used like this, and record what you are told.

Assumptions about what can be blocked are exactly the kind of thing worth having answered rather than guessed.

Nothing on this list decides what has to stay clear; escape and fire safety belong with a qualified professional and the local authority.

Walk the route from the main door to where you would sit, and note everything you would have to pass, step around or squeeze between.

This walk finds the pinch points that a plan view hides, and it can be done in the room you already have.

Note whether the room is also the way through to somewhere else, since a through-route takes a strip of floor that furniture cannot have.

Rooms that double as corridors need their circulation decided first and their furniture fitted around it afterwards.

Consider where people stand when the room is full, since standing space is almost never drawn and is always needed at gatherings.

Every arrangement has a version of itself with more people in it, and that version needs somewhere to put them.

Walk the same route carrying a tray or a laundry basket with both hands full, and note where you currently have to turn sideways.

The two handed walk is the honest test of a gap, and it reveals problems that an empty handed walk forgives.

Note where a vacuum cleaner, a pram or a wheeled bag has to reach, and whether the arrangement leaves each of them a way through.

Furniture that has to be moved before the room can be cleaned tends to stop being moved, and the room shows it.

Decide what the seating should face, and accept early that a window, a fire and a screen rarely sit in the same direction as each other.

Naming the winner is what allows the other elements to be treated as secondary rather than fought over later.

Write down which focal point matters most in the evening and which matters most during the day, since the answer is often not the same.

A room used mainly after dark can be arranged very differently from one used mainly in daylight.

Note whether the room has one obvious centre or two competing halves, and decide whether you would treat it as a single space or as two areas.

Long rooms often work better as two smaller arrangements than as one stretched arrangement that suits neither end.

Consider whether the arrangement leaves anyone facing a blank wall, and whether that seat would then quietly be avoided by everybody.

Every layout has a worst seat, and it is better to know which one it is before the furniture arrives.

Record whether a screen has to be visible from every seat or only from the main ones, because this decides how far the layout has to bend.

Insisting that every seat sees the screen is the single requirement that most often distorts a living room plan.

Note which way the main window faces and where the sun actually reaches into the room at different times of the day.

Owners often describe a room as sunny on the strength of one hour, and the rest of the day tells a different story.

Mark the part of the floor that takes direct sun, since that is where fabric, timber and paper age fastest and most visibly.

Knowing the sunny strip in advance affects where a rug, a sofa or a bookcase should sit.

How a particular fabric, timber or finish responds to direct sunlight should be confirmed with the supplier or maker.

Consider whether low sun ever falls straight into the seating position, and note what would be needed at the window if it does.

Glare in the eyes at one time of day is enough to make people abandon a seat entirely.

Note how dark the room feels on a dull overcast day, which is the light most of the year is genuinely seen in.

Finishes and layouts chosen on a bright day can feel heavy in the light the room usually has.

Record where curtains or blinds would gather when fully open, and whether that would cover part of the glass or part of the wall.

Where the covering stacks decides how much daylight the room keeps and how much wall remains usable.

Mark the footprint of the main pieces on the floor with tape and leave it in place long enough to live around it before deciding anything.

Living around the tape reveals the routes and habits that a single look at the plan cannot.

Sit down in each marked position and note what you can see, what you can reach and what you would have to stand up for.

A seat is defined by what it looks at and what it can reach, neither of which appears on a layout drawing.

Use cardboard or existing furniture to stand in for the height of a tall unit, since height changes a room far more than plan area suggests.

Two arrangements identical on plan can feel completely different once one of them has something tall in it.

Photograph the taped layout from the doorway, because a photograph shows crowding that the eye forgives while you are standing in the room.

The doorway view is the one every visitor gets, and it is the view most people never test.

Write down anything the tape revealed that the drawing did not, and take those notes to the designer rather than relying on memory.

Findings from a full size test are the most useful thing an owner can bring to a design conversation.

Walk the delivery route from the street to the room and note every turn, narrowing, low ceiling, handrail and awkward stair on the way.

Long pieces usually fail at a turn rather than at a doorway, and turns are the thing people forget to record.

Note whether a door frame, handrail or radiator would have to be taken off to get a piece in, and ask who would be responsible for doing it.

Nobody wants this question answered on the doorstep with a delivery crew waiting.

Removing and refitting any part of the building to allow a delivery is work for a qualified trade rather than a delivery crew.

Ask suppliers what information they need about the access route, and gather it before ordering rather than after something has been made.

Suppliers set their own access requirements, and meeting them is far easier before an order exists.

Consider whether a piece could arrive in parts or be assembled in the room, and record which suppliers say they can do that.

Assembly in the room turns an impossible access route into a manageable one for some pieces.

Note the route out as well as the route in, since anything being removed has exactly the same problem in reverse.

Old furniture that cannot leave the room becomes an obstacle on the day the new arrangement arrives.

Write down the arrangement you have settled on together with the assumption behind it, such as who sits where and what they are facing.

The assumptions are what get quietly broken when a drawing is revised, so they need to be visible in writing.

Record which pieces are fixed points in the plan and which could move if something else has to change.

Deciding in advance what would give way stops the layout being reduced by default rather than by choice.

Treat the measurements you take yourself as rough, and ask the designer or joiner to take their own before anything is made.

Owner measurements are ideal for thinking and unreliable for manufacture, and saying so avoids a painful misunderstanding.

List the questions the layout raised that you cannot answer yourself, and keep them together for the professionals you will speak to.

A single list of open questions is worth more in a meeting than a folder of half remembered concerns.

Note the date on your sketches and photographs so later versions of the plan can be compared against what you originally asked for.

Layouts drift through revisions, and dated notes are the only reliable record of where the drift started.
