Guides
Measure your home's facing direction with a phone: where to stand, how to hold it, how to avoid metal interference and why to record degrees, not names.
Set polarity on a floor plan correctly: find the true centre, enter the facing degree, check the main door, and avoid errors that skew every feng shui finding.
A checklist before your first architect meeting: land papers, measurements and facing degree, family needs, site photos and birth years — so the meeting leads to decisions.
How to read Home Check's 9-section feng shui analysis: which sections first, what the levels mean, the three tiers of actions, read-aloud and PDF.
The water mouth is where water leaves a site. How to find it at the grand, middle and small scales on a map: degree, mountain and confidence.
Gentle feng shui fixes: move and turn furniture, change the bed head, swap room uses, break door alignments — and when a re-layout is really needed.
Laying out a 4–5 m tube house for light and air: stairs with a light well mid-house, compact bathrooms, a one-side corridor, rear ventilation — with codes.
Turn a paper, printed or scanned plan into a digital one: shoot it clearly, one photo per floor, confirm what the assistant reads, then set polarity.
LiDAR-scan a whole home with a LiDAR iPhone or iPad: prepare the rooms, walk one loop the right way, check the 3D model, then go straight to the 2D plan.
Measure a home with a Bluetooth laser meter: activate and connect it, measure outer walls first, then details — each reading goes into the plan.
