Finding the Perfect Balance Between Nature, Comfort, and Quick Setup
Our client in Bulgaria was seeking an eco-friendly, modern, and space-efficient housing solution to place on a beautiful hillside property with panoramic natural views.
Traditional construction methods presented significant challenges:
- High Labor and Material Costs: Local construction is time-consuming and expensive.
- Environmental Impact: Heavy site work disrupts the natural surrounding landscape.
- Weather Resistance: The home needed strong thermal insulation and durability against European seasonal shifts.
The solution? A custom-designed 20FT Expandable house engineered for fast deployment, high energy efficiency, and refined architectural aesthetics.
A Tailored 20FT Expandable House with High-End Upgrades
To seamlessly blend with the hillside landscape while providing full residential functionality, we customized the unit down to the finest structural and interior details.
1. Aesthetic Exterior with Natural Blend
- Wood-Grain Exterior Wall Panel (D-081): Equipped with 75 mm composite insulation (60 mm EPS + carved metal plate), offering exceptional thermal insulation while replicating the natural beauty of real wood.
- Extended Roof Design: Extended by 20 cm on both sides to provide extra rain protection and an extended architectural profile.
- Integrated Terrace System: A spacious outdoor deck (9 m x 2 m) connected directly to the entrance, allowing occupants to enjoy outdoor living effortlessly.
2. Premium Interior Layout & Amenities
- Fully Equipped L-Shape Kitchen: Features premium cabinetry, integrated countertop cutouts for induction cooktops (2200W), and dedicated space reserved for a refrigerator, oven, and dishwasher with pre-installed plumbing.
- Dry-Wet Separated Bathroom: Designed with a frosted glass shower partition, marble shower basin with sloped drainage, UV stone-patterned wall panels (Rhein Stone), mirror cabinet, and instant water heater.
- Comfortable Living Space: 4.0 mm SPC click flooring, solid white interior doors, and warm LED lighting creating a cozy ambience throughout.
3. Durability & Energy Efficiency
- Thermal-Break Aluminum Windows: Outward-hung and sliding windows with dark reflective gray-coated glass and integrated flyscreens for improved ventilation, energy efficiency, and privacy.
- Robust Electrical & Plumbing Standard: Built to international compliance standards with dedicated heavy-duty wiring (6 mm² main line, 4 mm² AC line) and high-grade PPR water pipe networks.
Results & Client Experience
The entire expandable unit was prefabricated, fully fitted with internal wiring, plumbing, and fixtures, and transported smoothly to Bulgaria.
- Effortless Assembly: The main structure expanded rapidly on-site, drastically shortening construction timelines from months to days.
- Stunning Visual Harmony: The wood-textured facade seamlessly integrated into the green Bulgarian hills.
- Turnkey Living: From cooking in the L-shaped kitchen to taking a hot shower in the luxury bathroom, the home delivered immediate residential comfort right out of the container.
“The quality of the materials and the wood finish exceeded our expectations. It fits into the hills of Bulgaria like it was always meant to be there, and the entire setup process was effortless.”
