2. Additional Site Costs to Plan Alongside the House Price

To prevent unexpected budget overruns, our team itemizes site-related works transparently before contract signing:

1. Foundation Engineering: Reinforced concrete footing pads for firm soil, or bored piles/micropiles for soft clay regions such as Greater Bangkok.
2. Transport & Crane Installation: Calculated transparently based on distance from our factory and road access width.
3. External Utility Hookups: Internal electrical conduits and plumbing are pre-installed inside the modules; on-site work only requires connecting the main power cable and septic tank.
