Modular vs Conventional Housing: Comparing Time, Cost & Performance
Compare identical net floor area, specifications, thermal comfort and finishes. Why industrial offsite manufacturing delivers 60% faster schedules with zero weather disruption.
1. Apples to Apples: Comparing Identical Specifications
Comparing a fully-finished modular house with a bare brick shell is a common industry mistake. A genuine evaluation requires identical net usable areas, equal thermal U-values, identical triple-glazed joinery, and fully integrated bathroom fixtures.
When specifications are standardized, modular construction demonstrates remarkable advantages in finish quality and acoustic precision due to controlled factory environments.
2. The Parallel Schedule Advantage: 60% Faster Project Delivery
In traditional building, site works proceed strictly in series: excavation, foundation, concrete curing, brickwork, plastering, drying, and interior fitout. Bad weather stalls the entire critical path.
In SERMODULA modular engineering, foundations are cast on-site simultaneously while modules are manufactured, insulated and fitted out in the factory. Once foundations cure, the entire building is craned and enclosed in 2 to 5 days.
