P Home by Studio Krubka: Innovative Mixed-Use Architecture in Bangkok

P Home, designed by Studio Krubka, is a striking example of mixed-use architecture that combines office, rental, and residential functions on a compact 400 sqm plot in Bangkok. Completed in 2025, the project demonstrates how urban density can be managed while creating flexible, high-quality living and working environments.

The client’s brief was clear: ground-level parking with separate entrances for offices and residence, offices on the second floor and mezzanine, and residential spaces on the upper levels, including a music rehearsal room and a fitness area. The design balances functionality, aesthetics, and natural elements within strict height and area constraints.

Design Concept

The primary challenge was integrating diverse programs into a limited footprint. Studio Krubka employed a flat slab system with wall-bearing structures, eliminating beams to create vertical openness and flexible spatial organization. Fair-faced reinforced concrete was the key material, poured using high-strength, low-slump concrete in steel molds to achieve a smooth, uniform surface distinct from conventional plywood finishes.

The building separates its users into two distinct groups: office tenants and residents, with carefully planned circulation for both. A red steel staircase acts as the vertical core for office users, contrasting the solid concrete with a light, feminine aesthetic, while the homeowner uses a private elevator.

Open-plan office areas maximize flexibility, with enclosed zones along the sides. Skylights and strategically placed openings provide natural light and ventilation, with a central skylit atrium guiding daylight through the office levels.

Residential Design

The residential level is distinctly separated from the office by a steel door, though select openings maintain visual connections across balconies and skylights. A semi-outdoor transitional sequence softens the shift from urban density to private living spaces.

At the heart of the residence is a central courtyard featuring a Devil Tree (Alstonia scholaris), visible from nearly every room. The courtyard functions both as a ventilation shaft and as a natural focal point, channeling breezes into the elevated living room and creating a symbolic connection to nature.

The double-height living room features large sliding doors on the east and west facades for cross-ventilation and daylighting, enabling energy-efficient living without air conditioning during favorable weather. A retractable fabric canopy provides shade while maintaining airflow, and skylights over the pantry, music room, and guest bathroom ensure tailored natural lighting.

Materiality & Interiors

Studio Krubka embraced material experimentation:

• Steel-cast fair-faced concrete for crisp, monolithic surfaces
• Glass blocks to diffuse light and create visual interest
• Perforated ventilation blocks introducing texture and rhythm

The interiors remain minimalist, allowing the architecture and materials to define the spatial experience. Movement from the office through the courtyard to bedrooms ensures occupants remain connected with light, air, and nature throughout the day.

P Home is a prime example of how mixed-use architecture can coexist harmoniously within a dense urban footprint. By combining functional office spaces, flexible residential areas, and strong natural elements, Studio Krubka demonstrates how thoughtful design can elevate urban living in Bangkok.
