LDD-13 Ā· South Bay Layout
š Unified by LDD-30 Central Mechanical Core Master Strategy (v6.0, 2026-05-17). LDD-30 §5 formally locates the solar lithium battery bank + south manifold cluster inside the garage envelope as Zone 3 of the mechanical core distribution. Garage thermal strategy (low tempered slab) is now binding for battery environment stability and condensation control.

ā ļø STALE detail ā flagged 2026-05-17. This render shows the garage bays as clean and empty, but per LDD-30 §5 the garage is now formally Zone 3 of the mechanical core: a solar lithium battery bank and the south manifold cluster (serving garage + workshop loops) now live inside the garage envelope. Priority: MEDIUM ā the render's general "clean production zone" character still holds, but the battery + manifold are missing from the composition. Update the inline prompt below to add a wall-mounted lithium battery enclosure (matte charcoal, NFPA 855-compliant placement against an interior wall) + a south manifold cluster (similar visual language to the mech-room north manifold) and regenerate via Codex when refreshed.
Locked decisions
- Overall: 60' EāW Ć 30' NāS
- LOW above (second floor)
Layout (rooms overlap with transport spine ā not strictly linear)
- Equipment room (~10' Ć 13', tucked into corner, shares wall with mezzanine)
- Workshop WC (shares the equipment-room corner)
- Workshop main (~23' Ć 16' work zone with 7' clear transport spine ā multi-use thoroughfare, not a dedicated hallway)
- Service zone (overlaps workshop transport spine)
- Material lift ā 6'Ć7' shaft, 5'Ć6' platform. Asgard Press inventory transport between ground and LOW; NOT a passenger elevator. Out of passenger-lift codes; falls under industrial material-lift / dumbwaiter classification.
- Hybrid receiving / storage bay (Asgard Press operational zone)
- 3-car garage bays
Open items / engineer review
- Dimensions don't close at 60' ā equipment 10' + workshop 23' + lift 7' + hybrid + 3 garage bays (~27ā30') exceeds 60'. Reconcile.
- Lift specs ā capacity? hydraulic vs traction? code-compliant openings?
- Hybrid bay function ā packages? vehicles? equipment?
- Garage door type, width per bay, opener, glazing
- Equipment room ventilation + cooling + acoustic treatment
Cost drivers (revised ā lift reclassified)
- Material lift (Asgard Press inventory, not passenger): dumbwaiter / industrial material-lift = $5ā15K installed. Previously $25ā55K passenger class, corrected.
- 3 garage doors with operators: $12ā27K
- Hybrid bay door: $3ā6K
- Equipment room buildout (mineral wool reused from LDD-11 spec): $3ā6K
Builder's response (Round 2, accepted)
- Lift SPOF ā withdrawn. Material lift only; failure = inventory stays on ground for a day.
- Dimensions reconciliation ā withdrawn. Rooms are nested/overlapping, not linear; my misreading.
- South face thermal ā withdrawn. Insulated sectional doors + south solar gain (winter) + 4' overhang (summer shading) is correct passive solar logic.
- Equipment room noise ā solved by reusing mineral wool + double-stud already specified for habitable zones; not a separate $4ā8K add-on.
- Workshop / hybrid overlap ā confirmed: hybrid east side, transport spine through lift to LOW.
Remaining air-gap concerns (much shorter list)
- Equipment room: verify mineral-wool spec extends here in construction drawings.
- Material-lift vendor + maintenance regimen still worth documenting ā even residential dumbwaiters have wearing parts (cables, motor).
