Explore the CAD parcel, compare hotel arrangements and test the assumptions that shape the project. Blue is the owner’s allowed building area.
Concentrate the hotel in the eastern blue area. Keep the western reserve for a planted outlook, privacy and low-impact landscape studies. Avoid placing covered decks, pool tanks or plant structures outside blue.
Paired 6 × 5 m units improve room comfort. Compact 3 × 5 m rooms follow the owner’s outer footprint and require careful furniture, bathroom and accessible-room planning.
Building-control Area 3 and environmental Area 2 are different maps. The latter is a working lowland assumption, pending surveyed altitude, slope and authoritative map confirmation.

The 30% report condition concerns “other activities.” It is retained as a conservative study target; it does not prove which permit classification the hotel falls under. The environmental green-space rule is an additional test.
193 levelled points from the 20 Aug 2025 ground survey (3 Rai Samui), triangulated into a Delaunay TIN of 355 triangles. Contours are cut from that mesh, so each line is interpolated between measured points, not from a satellite grid. Triangles with any edge longer than 32 m are dropped, so the surface stops where the surveyor stopped.
Model heights are shown above the lowest surveyed level (10.31 m, local datum). Each block sits at its finished floor level (FFL): the ground at its centre unless you set one in the block editor or in Levels & earthworks. Sun shadows fall on the surveyed ground when the terrain is shown.
The survey grid is Indian 1975 / UTM zone 47N (central meridian 99° E). The parcel is the villa-3 property line (Troop - บ้าน villa-3.dxf, sheet REMOVE ROAD), used exactly, so the pre-construct platform, hatch and slot lines sit on it with no fit error. The survey is registered to that line by a rigid fit of its 12 concrete boundary markers (RMS 1.04 m, largest 1.41 m). Project axes rotate -4.3260° to the survey grid (Studio 10 used −5.5013°, about 1.2° off). The Maps pin is the road entrance and agrees with the survey latitude to 1.0 m.
SURVEY_TIN_CONTOUR_* layers, Z = survey level) at one interval only.UTM output uses the documented transform and lands on the survey grid (boundary markers within 1.4 m of the villa-3 line). Relative geometry is exact.
Guests walk between the entrance, reception and room corridors; staff use a separate service destination. Paths route around expanded block, pool and parking obstacles.
One-metre navigation grid, 0.55 m obstacle clearance, no diagonal corner cutting. Travel times assume constant walking speed; crowd interaction, doors, stairs and evacuation capacity are not simulated.
Six bays sit at the front of the site, entered from the east reference entrance. No separate 6 m aisle is reserved; the manoeuvring apron is carried in the hard-surface allowance. The entrance road connection still needs confirmation.
Calculated at the entrance coordinates in UTC+7. True-north rotation comes from the two CAD sheets. Shadows are a flat-ground study; verify terrain, neighbouring objects and glazing.
The wind arrows are a direction study, not CFD. Use NE/SW seasonal scenarios, then validate local wind and ventilation with site measurements.
Tree positions are proposed landscape markers. They are never labelled surveyed or existing.
Editable design assumptions: no site rain record or soil infiltration test supplied. Runoff is a volume screen, not a detention/drainage design. Confirm lawful discharge and wastewater treatment capacity.
Concept cost only. Gross floor area includes every floor, corridors and the selected mezzanine. Land, tax, financing, FF&E, pre-opening, working capital and off-site road/utility upgrades are excluded. Upper-floor bridges between reserved cores and corridors need detailed design and an additional area/cost allowance.
The duration is a user scenario, not a promised approval/construction schedule. EIA/IEE, surveying, geotechnical work and utility agreements can change the critical path.
HTML works offline. Save project stores site identity, edited blocks and assumptions. A project from the old site is rejected to prevent mixed geometry.
Each slot saves the full study state. Restore supports Undo. Variant values are recalculated, not copied KPI labels.
Coverage uses the polygon union inside the site, avoiding double-counting overlapping roofs. Physical overlaps still produce errors. Net room area is distinct from outer dimensions and gross floor area.
