LGSF vs. Timber Construction
vs. Masonry House

Clear comparison of cost, speed, and quality of construction for investors, architects, and builders.

Did you know? LGSF and timber construction are so-called dry construction methods – after assembling the skeleton and insulation, they proceed directly to finishing. Masonry construction requires plastering, chasing, and weeks of drying additionally.

LGSF – Skymax

After skeleton assembly

  • Load-bearing steel structure completed
  • Roof trusses installed
  • Installations routed inside the profile
  • Blow in / insert insulation
  • Internal sheathing (Plasterboard/OSB)
  • Facade / ventilated cladding
Timber construction

After skeleton assembly

  • Wooden frame / CLT panels completed
  • Vapor barrier and OSB boards
  • Windows installed (structure protection)
  • Insulation in panels / mineral wool
  • Internal sheathing (Plasterboard)
  • Facade / ventilated cladding
Masonry construction

After completion of the shell construction

  • Load-bearing masonry built
  • Ceilings and roof structure completed
  • Internal plastering (wet process)
  • Plaster drying – weeks!
  • Wall chasing for electrical/plumbing
  • External plaster or facade
  • ETICS or ventilated facade

Key insight: LGSF ≈ Timber construction

Both technologies are so-called dry construction methods. After skeleton assembly and insulation, the process moves directly to sheathing and facade – no waiting for plaster drying, no chasing. Compared to masonry construction, you save weeks of work and eliminate moisture risks in the structure. Masonry requires wet processes that extend the schedule and increase the risk of mold formation due to insufficient drying.

2–6
weeks for the skeleton

LGSF – Skymax

CNC production in the hall, assembly of prefabricated panels on site. Turnkey house: 4–7 months.
4–10
weeks for the skeleton

Timber construction

Prefabricated panels or system construction. Turnkey house: 6–9 months.
3–5
months for shell construction

Masonry construction

Traditional masonry, wet processes, drying. Turnkey house: 12–16 months.

What does this mean for the investor?

Shorter construction time = faster return on investment. For a development project with 10 houses, a 6–9 month difference compared to masonry construction represents a real savings on financing and earlier cash flow. LGSF also minimizes the risk of material or labor cost increases during construction thanks to precise pre-manufacturing.
