Model status: Nine 2 ft 6 in square T01 tables; 1 ft 5 in counter depth; selected Study07 arrangement preserved.
Room view · Blender
Selected commons tables and wraparound counter. Existing seating and access limitations remain unchanged.
CAD reference and downloads
CAD contents: mixed 2D references and 3D fit-out. 354 solids. Reference lines and open faces are not closed room volumes; use the extract provenance for exact contents.
Unsectioned CAD wireframe · SVG reference
Diagonal mesh edges are not walls, bracing or access routes. Check the full-floor model for adjoining context.
Room extracts retain source shape geometry and shared openings; they do not reproduce the full document’s parametric dependency history. Use the full-floor file for coordinated editing.
Layout notes
Keep all recorded occupied-chair/pull-out conflicts; do not claim comfortable simultaneous capacity.
Three table banks need a selected contained feeder method; no aisle/door/step floor crossings.
Optional one extra receptacle at each T3/T9/T6 needs approval.
Counter users must turn or relocate to view the presentation screen.
Revision, sources and future updates
Model publication: R06, 12 September 2026. FF02 C04 replaces the C03 insulated panels and opaque roof with aluminium-framed glazing and a glass roof. The first-floor Blender, CAD and FF02 extract are coordinated; other rooms and the ground floor are unchanged. S02 remains the published service plan and has not been recalculated for the glass enclosure. Original models and historical releases are preserved, with separate source and download hashes.
Changes require a coordinated export, room-plan regeneration, service-note review and tested website release. Saving a local Blender or CAD file does not automatically publish it. Pending or unreviewed models are never substituted silently.

Electrical and setup plan.
S02, 12 September 2026: sockets, lighting, air conditioning, AV, cameras, access doors and backup power for both floors, reconciled to the three-phase, 10 kW sanctioned (LT commercial) supply.
Planning estimate from the measured room programme and the 12 September 2026 decisions. Symbol positions are indicative and derived from the published CAD; a licensed contractor confirms positions, cable sizing, protection coordination and earthing on site. Not a certified electrical design, not an installed-services record, and not a fire or occupancy approval. S01 room service quantities remain the historical scenario.
Design case7.42 kW
25 people concurrent, four cabins in use, a GPU job running: 2.6 kW of headroom under 10 kW.
Phase balance3.2 · 3.38 · 3.33 kW
R, Y, B at the design case. Hall ACs split across R and Y; the UPS sits on B.
Proposed backup3 kVA UPS · 2 h target
GPUs, printers, network, hall AV and access doors; estimated nominal battery capacity 6.16 kWh, assuming 80% depth of discharge.
Ground floor: 9 rooms, 52 six-ampere and 13 sixteen-ampere points, 34 luminaires, 11 fans, 3 AC units. Typical occupied demand for the floor about 7.9 kW before diversity. Positions are indicative.

Backup power and house rules
UPS. 3 kVA online double-conversion, about 2.7 kW at 0.9 power factor. Connected UPS load 3353 W, average 2218 W, 2 h at the average needs 4.93 kWh delivered. Recommended battery: 48 V 120 Ah LiFePO4 (5.8 kWh) minimum; 48 V 150 Ah (7.2 kWh) recommended for headroom. Lead-acid alternative: 4 x 12 V 200 Ah tubular at 48 V (9.6 kWh nominal, ~4.8 kWh usable at 50% DoD): meets 2 h only at average load, ~180 kg, needs a ventilated rack. Charger limited to about 500 W. Connected UPS load (3.25 kW) exceeds a 3 kVA unit; average (2.0 kW) fits. Rule: during an event the AV rides on the UPS while printer starts are held, or step up to 5 kVA.
Floor inverters. Ground: 2 kVA / 24 V pure sine with 2 x 12 V 150 Ah tubular (3.6 kWh nominal), covering GF lights, 8 BLDC fans, reception board, 2 commons duplex per rail, roughly 1.7 h. First: 1.5 kVA / 24 V pure sine with 2 x 12 V 150 Ah tubular (3.6 kWh nominal), covering FF lights, 3 BLDC fans, one duplex per cabin, roughly 2.4 h. AC, kitchen and workshop raw circuits are never on an inverter.
Cabin ACs run at 25 to 26 C; hall ACs run only during events and cabin ACs go off by the event start.
GPU training jobs are scheduled outside event hours; short inference or CAD work is fine any time.
Kettle and microwave are on separate circuits and not used together during an event peak; no geysers or heaters anywhere.
Battery chargers are current-limited and bulk-charge at night; after a daytime outage expect up to 1.3 kW of recharge on top of the running load.
An energy monitor with per-phase clamps at the main DB shows live demand on the reception screen; at 9 kW it flags, at 9.5 kW the hall AC 2 contactor drops out.
The native FreeCAD files carry the reference architecture copied from the published CAD plus an “S02 Electrical” group with one object per symbol (room, kind and rating in the label, at mounting height). Fresh save and reopen passed for both documents (record). No AI-generated imagery.
