The command position

The oldest rule in domestic feng shui and the one every school shares. Solid behind, the door in view, out of its line. Where it comes from in the Book of Burial, what a seated person can actually see, how it places the bed, the desk, the main seat and the stove, what the research on seating says, and the order in which to give it up.

If feng shui indoors had to be reduced to one rule, this would be it, and every school would sign. The position from which you can see the door without being in line with it, with something solid at your back, is where the tradition puts the bed, the desk, the seat you sit in most and, if it can, the cook. The rule is older than the compass and needs no instrument to check. It is also the one rule in the tradition that the research on how people choose a seat supports in detail, and this essay gives that research beside the rule.

Where it comes from

The Form school’s ideal site is a protected hollow: a hill behind, ridges to either side, open ground and water in front. The Zangshu, the Book of Burial, gives the four their names in one sentence, the Azure Dragon on the left, the White Tiger on the right, the Red Bird before and the Black Tortoise behind, and the yin house page draws the valley the sentence describes. Yoon’s account of the landform vocabulary makes the logic plain: the site is sheltered from what it cannot see and open to what it can. The command position is that site at the scale of a person. The wall is the hill; the room in front is the open ground; the door is the approach along which anything arriving will come. A grave was given the position first, then a house, then a seat, and the rule kept its shape at every scale.

The three conditions

Solid behind. A wall, not a window, partition or open space. The tradition reads a window behind the head as no support; the practical version is draughts, noise and light where you least want them, and a person behind you whom you cannot see.

The door in view. Without turning, you should see who comes in. This is the condition the tradition weights most, and the one the psychology best explains.

Out of the door’s line. Not directly aligned with the doorway: the tradition reads the axis of a door as the path along which qi moves fastest, and a body in that path as in a draught of it. The position that satisfies all three is usually diagonal to the door, across the room from it.

Fig. 01 What a seated person sees without turning. The same room, door at the bottom left, with the chair facing three ways; the soft wedge is the binocular field of view, about a hundred and twenty degrees, drawn from the sitter’s eye. A: the desk against the far wall, the sitter facing it, the door behind them and wholly outside the field; anyone entering is heard before they are seen, which is the arrangement the tradition names as worst and most people fall into. B: the desk along the side wall, the door at the edge of the field; it can be seen, but only by turning the head, and a person working looks away from it. C: the desk on the diagonal, its back to the corner, the door well inside the field; the sitter sees it without moving, and the wall behind them is solid. The third is the command position, and the drawing is the reason it works. The field of view is Panero and Zelnik’s: about sixty degrees to either side of the line of sight for both eyes together, with peripheral vision beyond it to about ninety, and the eyes turning comfortably fifteen degrees and the head forty-five. A door within thirty degrees of the line of sight is seen without effort; one at ninety is a glimpse; one at a hundred and eighty is a sound. Scale 40 units to the metre.

The drawing puts the second condition in the terms of the body. A person sitting still sees about a hundred and twenty degrees with both eyes, sixty to either side of the line of sight, and glimpses movement to about ninety; the eyes turn fifteen degrees without effort and the head forty-five. Panero and Zelnik’s handbook, from which the figures come, is the one designers size rooms by. A door within thirty degrees of where a person is looking is seen without a movement; a door at ninety is a turn of the head; a door behind is a sound, and a person who has to identify every sound behind them with a turn is a person who is working with half their attention on the door. The command position puts the door inside the wedge, and the rest of the rule is about what is outside it.

Fig. 02 The command position, four times. In each room the door is at the bottom left; the solid mark is the recommended position and the dashed line is its view of the door. The same three conditions place a bed, a desk, the main seat and, on an island, the cook. Where a room cannot give all three, keep the solid wall behind and give up the diagonal first. The stove on an island is the tradition’s ideal and a renovation; a mirror or polished splashback that shows the door is the everyday version.

Four applications

The bed. Head to the solid wall, door visible from the pillow, feet not pointing at the door. The bed placement guide draws the exceptions, and the bed for two guide the case where two people need the same wall.

The desk. Wall behind the chair, door in view, and a fourth condition the bed does not need: light from the side, so that it falls on the work and not on the face or the screen. The desk pushed against a wall, with the door at the sitter’s back, is the arrangement most people fall into and the one the tradition names as worst; the home office page takes it apart, and panel A of the drawing above shows why it feels as it does.

The main seat. The sofa or chair you sit in most: back to a wall, facing the room and the door. A sofa with its back to the door or to a window is read exactly as a bed would be. The living room page arranges the rest of the seating around it, and the sofa placement guide gives the compromises for a room with a door on every wall.

The stove. The cook, not the appliance, is what the tradition is placing. A stove on a wall with the door behind the cook leaves them working with their back to whatever comes in; the tradition’s ideal is an island or peninsula from which the cook faces the room. Where the stove cannot move, a reflective surface that shows the door is the usual adaptation. The kitchen page has the rest.

One rule, eight seats

Fig. 03 One rule, eight seats. The command position is a single sentence, a solid wall behind, the door in view and not in its line, and the site applies it to every place it puts a body, with a third condition that changes with the seat: the bed’s is the window and the beam it must not lie under, the desk’s is the side the window goes, the sofa’s is the other seats, the host’s is the guest, the cook’s is the sink, the sick bed’s is the view, the child’s is the writing hand, the till’s is the door’s line. The ledger gives the eight with the guide that draws each, so that a reader who has learned the rule in one room can find it in the next. Where two conditions cannot both be had, the guides give the order to give them up in, and it is always the same: the wall first, the door second, the third condition last. The rule is the Form school’s and the site’s first; the compass schools’ direction for a bed or a desk is applied after it, never instead, and the Eight Mansions essay says so.

The rule is one sentence and the site applies it eight times, and the ledger above gives the eight in one place so that a reader who has learned it in a bedroom can find it in a shop. The wall and the door are the same in every row: a solid surface behind the body and the door seen without being faced or lain in the line of. The third condition is the one that changes with the seat, and it is where the rooms differ from one another. The bed’s third condition is the window and the beam it must not lie under, which the bed placement guide draws; the desk’s is the side the window goes, on the far side of the writing hand, which the desk placement guide gives for an adult and the student’s desk for a child; the sofa’s is the other seats, which must see each other, in the sofa placement guide; the host’s at table is the guest, who faces the host and not the door, on the dining room page; the cook’s is the sink, a worktop away from the hob, on the kitchen page, whose command position is the one the tradition most often has to compromise; the sick bed’s is the view, the window and its trees seen from the pillow, in the recovering at home guide; and the till’s is the door’s line, which it must see and not stand in, in the workplaces guide. Where two conditions cannot both be had, and in a small flat they often cannot, every guide gives them up in the same order, which is the order of their weight in the tradition and in the research: the wall first, because a back that is covered is the condition the prospect-and-refuge studies find people choose before any other; the door second, because a door seen is a door that need not be listened for; and the third condition last, because it is the one a screen, a lamp or a turned chair can most often supply. A reader who keeps the order has the whole of the Form school’s interior practice in three words and a ledger.

What the evidence says

Evidence · Prospect and refuge

Appleton’s prospect–refuge hypothesis proposes that people prefer environments that offer both a view and protection, because an animal that could see without being seen survived, and it has been widely used to explain seating and landscape preferences since. Hildebrand applied it to houses, and found the sheltered seat with the long view, the inglenook that looks down the room and out of the window, in almost every house people call pleasant, Frank Lloyd Wright’s above all. Kaplan and Kaplan’s work on restorative environments points the same way: places that can be surveyed without effort are experienced as calmer. None of this is a study of beds or desks. All of it makes the command position plausible as a matter of comfort, and none of it shows an effect on health or fortune.

Evidence · Where people sit when they can choose

The seating research is more direct. Sommer, watching where people sat in libraries, cafeterias and wards, found that the seat with the wall behind and the room in front went first, that people avoided seats that put their backs to a door, and that a person who could not get such a seat would turn a chair to make one. Robson’s review of restaurant seating finds the same preference in diners: the anchored table, against a wall or a partition, is chosen before the open one, and the party at it stays longer and spends more. Evans’s review of housing and mental health puts a name to the underlying variable, control over one’s space, and finds that it has measurable effects on wellbeing. The tradition’s rule is a description of what people do when nobody has told them anything.

What the rule is not

Compromises, in order

Most rooms cannot give all three conditions. Give them up in this order:

Give up the diagonal first. A position in line with the door but with a solid wall behind is better than a perfect angle with a window at your back. The line is a discomfort; the window is a draught, a light and a noise.
Give up the view second. If the only solid wall puts the door behind you, keep the wall and add a mirror on a side wall that shows the door without reflecting the bed, or turn the chair so that the door comes within the head’s turn.
Never give up the wall. If it seems you must, the room is asking for a different piece of furniture in that place, not for the bed. A tall solid headboard is a wall a bed brings with it, and the last resort before moving the bed to another room.

The three, given up in that order, drawn:

Fig. 04 The three conditions, given up in order. One: the bed has the wall behind its head, the door in view from the pillow and the door’s line clear of it, which is the rule. Two: the room has only one solid wall and it faces the door, so the bed stands in the door’s line; it keeps the wall, and the tradition accepts it. Three: the only solid wall puts the door behind the sleeper; the bed keeps the wall and a mirror on the side wall shows the door from the pillow without reflecting the bed. Four, ghosted: the bed floated in the middle of the room, which sees everything and is backed by nothing; the tradition puts a table there and the bed elsewhere. The order is the manuals’: the diagonal is the first thing to lose, the view the second, and the wall is not lost. A room that cannot give a bed a wall is a room that wants a different piece of furniture in that place.
