The design surrounding Ērģeme Castle is located in Valk L Municipality, positioned within a nature reserve. It focuses on environmental sustainability while promoting community involvement. The concept aims to blend built elements with the natural surroundings, creating spaces that encourage interaction and foster a sense of connection with nature.

Masterplan

Key features in the masterplan enhance accessibility for visitors. These include a bus stop, a garden, and designated parking. A rubbish area, exhibition dock, and bathing tub are also included. Such thoughtful arrangements promote movement throughout the site, facilitating access to each area and encouraging a relationship with the outdoor environment.

Interior Organization

The organization of interior spaces supports various functions. There is a main entrance, an area for equipment rental, and separate entrances for staff. A foyer exit, loading dock, and boiler room are also part of the design. This arrangement promotes efficiency, helping to manage the flow of both visitors and staff to ensure a positive experience.

Phased Development

The project follows a phased development approach, allowing gradual implementation. The first phase focuses on extending the annex to include a workshop area, kitchen, toilet, shower, and storage. The second phase involves renovations on the first floor to establish artist rooms, while the final phase aims to create a full area with ten rooms and a sauna. This method allows flexibility and minimizes potential disruption during construction.

Sustainable Features

Energy efficiency is a significant consideration in the design. Insulation is used to reduce energy loss, which is important in maintaining comfortable indoor conditions. Solar windows will generate more energy than traditional panels. Geothermal systems provide both heating and cooling, while heat recuperators work to enhance energy conservation.

In addition, rooms designed for contemporary artists include adjustable lighting to accommodate creative work. Both direct and diffused lighting options are utilized, ensuring that the different artistic activities can be supported effectively.

Paths throughout the garden connect to the main building, reinforcing the relationship between architecture and nature. Seating areas are included to encourage visitors to engage with their surroundings, making the experience more enjoyable.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
