40x16ft — CUSTOM — Shipping Container Conversion — GYM — Portable Space — No 1004

Dimensioned, furnished floor plan of the completed gym: two 40ft high-cube containers joined side by side into one 39'-5" × 15'-5" clear open volume — 609 SF net, 640 SF gross — with the glazed entry at the west end, both pairs of original ISO cargo doors at the east end, and the four training zones photographed in the gallery.

Equipment, circulation and floor-loading plan: the numbered schedule of every item photographed in the gallery, the 8'-0" Olympic platform centred on the joint line, the four-post power rack fixing detail, the 3'-0" clear central walkway and the keep-clear loading zone at the cargo doors.

Roof and reflected-ceiling plan: the capped and sealed joint between the two roof panels, retained camber and outward drainage, the exposed painted corrugation with no dropped ceiling, the four runs of surface LED battens, and the extract, inlet and air-conditioning layout.

Power and lighting layout: the external lockable isolator and 32A CEE inlet photographed on the unit, the ten-way consumer unit, twenty surface LED battens on two circuits, sixteen twin sockets around both long walls, air-conditioning and extract supplies, and the cross-bonding required across the joined shells.

Structural plan for the joined shells: the HSS 12×4×1/2 longitudinal beam spanning 39'-5" clear with no intermediate columns, the stitch-plated bottom rails, the retained uncut ISO end frames, the 200 psf assembly floor loading, and the prohibition on stacking after joining.

The three details that govern the conversion: the roof-level joint with its welded cover flashing and the HSS joining beam on its seat plate, the floor-level joint with stitch plates and the floating rubber tile, and the beam bearing onto the retained ISO end frame with its bolted bearing plate and deflection limit.

Bearing and setting-out plan for the joined 40'-0" × 16'-0" footprint: twenty-one bearing points across three rail lines including the critical joint line, the levelling-pad arrangement as the unit is photographed, pier and slab alternatives, corner-casting anchorage and the electrical service entry.

The two long elevations in satin black RAL 9005 exactly as photographed: unbroken corrugation with no window or door on either flank, the lockable rotary isolator and 32A CEE power inlet on the south corner post, the two air-conditioning condensers, the stencilled branding and the rubber levelling pads.

Both 16'-0" end elevations: the glazed entry end with its full-height picture window, double glazed door and transom lights in Container A alongside Container B's blank end, and the cargo-door end with all four original ISO leaves and their locking bars retained.

Transverse and longitudinal sections: A-A cut through the lifting platform showing the HSS joining beam on the centreline, the stitch-plated bottom rails and the removed side walls ghosted in, and B-B running the full length on the joint line showing the 7'-10" clear height under the beam and its 39'-5" clear span.
