NOVA SYSTEM
Semi-Precast Construction System
Landy Grand’s Semi-Precast
Construction System
Developed in collaboration with Japanese construction technology, this system sets a new standard in the homebuilding industry.
Precast components — such as columns, beams, and staircases — are manufactured in our quality-controlled factory and assembled on-site, significantly reducing construction time.
The Nova System also features flexible beam-to-column joints, offering strong resistance against high winds and seismic vibrations.

Backed by Decades of Homebuilding Experience
With over 8,000 homes successfully built, we proudly offer a 20-year structural warranty — ensuring your home remains beautiful, strong, and secure for years to come.
KEY FEATURES
Strong and Durable Structural Integrity
Using high-strength prestressed concrete components—columns, beams, and stairs—produced in high-standard factories (350 KSC), our structures match the strength of large-scale buildings, capable of withstanding strong winds and seismic forces. All materials meet TIS standards and undergo random quality inspections to ensure ongoing compliance. Construction is strictly supervised at every stage, backed by a 20-year structural warranty.
Internationally Recognized
Certified under ISO 9001:2015 by the United Kingdom Accreditation Service (UKAS), Landy Grand was the first in Thailand’s homebuilding industry to be accredited under ISO 9001:2000 (UKAS), reflecting our long-standing commitment to international standards.
Tested for Earthquake Vibration Simulation
Tested for Structural Strength with Lateral Cyclic Load (Earthquake Simulation)
The system has undergone ductility testing to confirm its ability to withstand lateral forces at connection points effectively.
Conducted in collaboration with a leading, internationally recognized engineering institute.
Fast and Precise Assembly
With factory-controlled precast components, installation is faster, on-site errors are minimized, and construction time is reduced. This approach ensures effective cost control, preventing budget overruns.
Supports Versatile Architectural Design
Compatible with various materials such as clay bricks, lightweight blocks, and other prefabricated elements — offering flexibility to suit any home style you envision.
Reduced Environmental Impact
Factory-based production minimizes dust, noise, and pollution at the construction site — helping protect nearby communities and the environment.

NOVA SYSTEM
COMPONENTS
Factory-Cast Columns and Beams with High-Strength Concrete
Using 350 KSC high-strength prestressed concrete, the same grade applied in major infrastructure projects such as expressways, bridges, and high-rise buildings, components are assembled on-site and connected to foundations, columns, and beams using the J-Bolt and Hidden Joint systems—effectively minimizing damage from vibrations and seismic forces.
Horizontal Casting Method for Columns and Beams
Ensures uniform distribution of aggregates (stone, sand, cement) throughout the structure — unlike traditional vertical casting with wood formwork, which often results in uneven material density.
Precast Staircase Structure
Cast with the same high-strength method as the main structure, the staircase is installed as an integrated part of the building — enhancing structural integrity and allowing easier access for inspection on upper floors during construction.

SYSTEM COMPARISON
Nova System
Conventional In-Situ Casting System
Structural Strength
Uses 350 KSC high-strength prestressed concrete, the same as in major infrastructure projects (expressways, bridges, dams, elevated roads) with long service life, produced in certified factories.
Employs prestressing wires with 16,800 KSC tensile strength, enabling smaller components without compromising load capacity, making transportation easier.
Consistent concrete quality using TIS-standard steel reinforcement for every piece.
Foundation, columns, and beams are connected using J-Bolt and Hidden Joint systems, allowing excellent load distribution and flexibility to reduce vibration damage.
Structural Strength
Concrete compressive strength of 150–240 KSC, typical for residential projects.
Uses SD40 reinforced steel with a tensile strength of approx. 4,000 KSC
Cast-in-place concrete has limited flexibility and may be prone to damage under strong vibrations or seismic activity.
Quality Control
Columns and beams are cast horizontally in the factory for even aggregate distribution (stone, sand, cement), ensuring consistent quality.
Accurate quality checks during production and installation.
Visible joints for easy inspection, as steel connections are external (not embedded in concrete).
Quality Control
Vertical casting often results in uneven aggregate distribution and air pockets, affecting strength.
Joints between columns and beams are hidden within concrete, making inspection difficult.
Surface finish, dimensions, and concrete quality are difficult to control precisely.
Surface quality and consistency are harder to control; weather delays (e.g., rain) can affect curing.
Skilled Labor
Factory production reduces on-site human error.
Installation by specialized crews trained for precast assembly.
Skilled Labor
