The same house drawing does not travel unchanged from a snow county to a coastal plot. The use case only tells us which constraint to ask for next.
Match a site to a systemScroll sideways. Each card is a placement, not a separate product brand.
For an illustrative alpine cabin row, obtain the mapped ground snow load before reviewing cold-formed steel framing. Ask for the tested mineral-wool separation assembly where cabins sit close together. Compare a panelized delivery with the measured road width and turning radius.
Salt exposure pushes the coating above a default Z275 note and forces cut-edge repair. Wind is written in m/s from the local map. A cedar rain screen can sit outside the panel, but the panel joint, not the timber, is the weather line the file checks.
A parcel of identical two-storey houses rewards a frozen option matrix. The 2-bed 2-bath plans buyers search for still need a party-wall core decision. Repeating a plan does not repeat a snow load from another county.
For an illustrative staff duplex brief, compare permanent modular construction on local foundations with the intended occupancy classification. Review the corridor separation as a complete assembly even if exterior panels use PIR.
A side-yard accessory unit is often a single volumetric module because the street closure is measured in hours. Check width including packaging against the route-specific permit thresholds. A wider architectural module needs a separate haul plan and may lose the time advantage.
A 750 sq ft or one-bedroom shell is still a structure. The 16x40 class can ship as panels. Calling it a tiny house does not remove the foundation interface or the sanitary freeze.
Factory completion is higher. Windows, partitions and a share of MEP can be in the box before it ships. The penalty is transport volume, crane size and a module width that the road will accept. A 6055 × 2435 × 2896 mm box is a reference geometry, not the size of every villa.
For a staff duplex handover, compare sanitary rough-ins and factory-fitted fixtures on the supplier scope sheet. Verify lifting points and crane access with the rigging plan, then identify who closes the corridor fire separation after modules are joined.
Cold-formed steel walls and floor cassettes pack densely. A container loading plan can place several shells in one 40HQ when the geometry allows, subject to package dimensions, payload and restraint. Site labour and weather exposure go up. Hole alignment and torque become the quality record.
For a mountain road with a restricted turning radius, compare panel bundle dimensions with the route survey. Cross-check the ground snow input on the signed calculation with the roof panel schedule and site connection drawings before release.
Foam cores are lighter and can post a lower U-value per millimetre. For a 75 mm PIR panel, ask for the declared thermal conductivity and thickness, then check the calculated assembly U-value in W/m²K with studs and joints included. Mineral wool adds mass and is the usual candidate when a separation, not just insulation, is required. Neither core is “fireproof,” and neither number survives a window or a joint that was never in the test.
Painted carbon steel on longer floor beams allows a specified color and a shop primer system. Galvanized light-gauge steel suits the wet wall zone. Weld zones on either route need a repair step. The file picks one system per member type instead of mixing unnamed coatings.
A house that can be lifted later is still subject to the code path of the place where people sleep. Temporary classification, when an authority grants it, has an expiry and a use limit. Permanent modular construction asks for the fuller foundation, energy and accessibility review. Lindal Cedar Homes will not relabel a permanent dwelling as temporary to skip that review.
Two-storey work adds a horizontal joint, a diaphragm note and a tighter tolerance on the foundation. That is a different calculation from a single-storey cabin even when the cladding looks similar.
Send country, snow or wind, storeys and whether the house must stay or may move. The reply will say which route is even eligible.
