How to read a floor plan for feng shui

A practitioner tradition read, not a valuation report. See the disclaimer below.

Buyers who wait until the actual viewing to think about feng shui end up doing it under pressure, standing in a unit with an agent and another family waiting outside. The better approach is to do the first pass at home, on the printed floor plan, with a pencil and a few minutes. This guide walks through exactly how, step by step, without needing a consultant on day one.

Start with orientation, not decoration

Before anything else, find north on the floor plan. HDB and most developer floor plans include a small north arrow somewhere on the page; if yours does not, the listing agent can usually get it from the original plan. Once you have north, locate the main door and note which direction it opens toward, and separately, which direction the door itself faces when you stand with your back to it looking out.

This single data point, the main door's facing, is the anchor for almost everything that follows in Compass School practice. It determines how the bagua grid gets laid over the unit for practitioners who use the compass method, and it is the reference point every other room gets measured against.

The bagua overlay, step by step

The bagua is a nine sector grid, eight outer sectors plus a centre, traditionally associated with career, knowledge and self cultivation, family, wealth, fame, relationships, children and creativity, and helpful people, arranged around the centre which represents overall health and balance. To use it on a floor plan, draw a rectangle or square around your unit's outline, ignoring balconies and bay windows that sit outside the main structure, then divide that rectangle into a three by three grid.

Here is where you need to pick a school and stay consistent. Classical compass based schools orient this grid to true compass direction, so the wealth sector, for example, always sits in the southeast of the unit regardless of where the door is. The Black Hat Sect, a more modern and widely taught approach outside China, instead anchors the grid to the wall the main door sits on, so the sector nearest the door is always treated as the entry point regardless of compass bearing. Once the grid is drawn, note which room falls into which sector, since a toilet or store room landing in what your chosen school calls the wealth or health sector is one of the more commonly flagged issues.

Red flags you can catch on paper before you visit

A handful of issues show up clearly on a floor plan without needing to see the unit in person. Trace a straight line starting at the main door: if it runs uninterrupted to a back door, a large window, or straight down a long corridor and out, this is what practitioners commonly call a piercing or through hall condition, where qi is thought to rush in and straight back out without settling in the home.

Also check whether the main door faces a toilet door directly across a short corridor or foyer, whether a toilet sits at or near the centre of the unit, sometimes called the tai chi point, and whether the outline of the unit is a clean rectangle or has a notch cut out of it, which reads as a missing corner in whichever bagua sector it falls into. In HDB maisonettes and landed layouts, also check whether a bedroom sits directly above or below the kitchen stove.

Room by room: what each space needs

The living room is usually read first, since it is what most main doors open into. Practitioners generally favour a seating arrangement where the main sofa backs onto a solid wall with a clear view of the entrance, described as a commanding position, without the sofa sitting directly in the door's straight line path.

The kitchen is read around the stove specifically, not the whole room. A stove that is visible from the main door, that faces the sink or fridge directly across a narrow galley layout, or that backs onto a window are the three points that come up most often, though schools differ on how strictly the window point is weighted. The main bedroom is read for whether the door aligns straight with the main entrance, whether the headboard can sit against a solid wall away from a shared toilet wall, and whether the bed sits under an exposed structural beam.

Toilets are generally kept away from the centre of the unit and away from direct alignment with the main door or the kitchen. Study rooms and children's rooms are sometimes placed with reference to the growth and knowledge sectors under the compass method, though this is a finer point that matters more to Compass School practitioners than to Form School ones, who weight the physical layout more heavily than sector placement.

For buyers eyeing a new launch, the floor plan alone will not tell you the full story, since stack position within the development and what the unit actually faces on the site plan matter just as much as the internal layout. Our guide to picking a new launch unit by feng shui covers stack selection and site plan reading specifically, and pairs well with the room by room checks here. It is also worth understanding how a unit's internal layout efficiency is measured in the first place, which our floor plan efficiency ratio guide explains, since an efficient layout and a feng shui friendly one frequently turn out to be the same layout.

Floor plan review checklist

• Locate the main door and note its compass bearing or the wall it sits on
• Overlay a nine box bagua grid using your preferred school's method, and note which one you used
• Trace a straight line from the main door through the unit and note anything it passes straight through
• Check whether the main door faces a toilet door directly
• Check where the toilet sits relative to the centre of the unit
• Check whether the floor plan is a regular rectangle or has a notch or missing corner
• Locate the kitchen stove and check what it faces or backs onto
• Locate the main bedroom and check its position relative to the main door and any toilets
• Note which bagua sector each room falls into
• Bring the marked up floor plan to the actual viewing to confirm against reality

Frequently asked questions

Can I check feng shui from a floor plan alone?

You can catch most of the structural and layout issues from a floor plan alone, which is exactly why practitioners and experienced buyers review the plan before booking a viewing. What a floor plan cannot tell you is the view outside each window, what the block or building actually faces on the ground, and how the unit feels once furnished, so a physical viewing still matters for the final call.

What is the bagua overlay and how do I use it?

The bagua overlay maps eight life areas plus a centre onto your unit's outline, traditionally corresponding to career, knowledge, family, wealth, fame, relationships, children and helpful people, radiating from the centre point of the home. Overlay it as a nine box grid onto your floor plan, aligned to either the main door or compass bearing depending on which school you follow, and check which rooms fall into which sector.

Do all feng shui schools agree on how to map the bagua?

No, and this is one of the more genuine disagreements between schools. Classical compass based schools anchor the bagua to the actual compass direction the main door faces. The Black Hat Sect, a more modern school, anchors the bagua to the wall the main door sits on regardless of compass direction. Both are actively practiced in Singapore, and a practitioner from one school may give a different reading of the same unit than one from the other.

What are the biggest red flags on a floor plan?

The most common ones on paper are a main door that lines up in a straight line with a back door or window, a main door facing a toilet door directly, a toilet sitting in the centre of the unit, and an L shaped or irregular floor plan with an obvious missing corner in one of the bagua sectors.

Does a north or south facing unit matter for feng shui?

Not directly; facing is read from compass bearing and what the door is positioned toward, not simply north versus south on its own. Separately, north south facing units are often preferred in Singapore for a practical reason that has nothing to do with feng shui: they avoid the harshest of the afternoon sun that east and west facing units take on directly, which affects heat and cooling cost rather than qi.
