The Monte D'Oiro Wine Hotel is located in a historic region known for its vineyards and traditional winemaking. The design blends modern elements with the characteristics of an existing winery and barrel room. Guests can experience both contemporary spaces and the heritage of the area. The concept focuses on creating “environment branches” that encourage interaction and connection with the landscape.

Design Concept

The approach to the design highlights a transition from historical features to contemporary styles. Visitors first encounter the old winery and barrel room, which embody traditional architectural forms. This connection to the past leads to the modern hotel, restaurant, and spa. By using simple and fragmented shapes, the design thoughtfully links the old with the new, allowing the spaces to coexist.

Accessibility Features

A key part of the design includes an underground tunnel that connects different areas of the complex. This feature makes it easier for all guests to navigate the site, including those with disabilities. The tunnel serves both a practical and symbolic role, fostering a user-friendly environment. It encourages people to move easily between spaces, enhancing overall experience and interaction.

Sustainability Initiatives

Sustainability is integral to the planning of the hotel. Below-ground water filtration tanks are designed to treat sewage water so it can be used for irrigation in the surrounding vineyards. This practice demonstrates a commitment to reducing waste and being environmentally responsible. The design prioritizes ecological health while maintaining comfort for guests.

Architectural Outcome

The Monte D'Oiro Wine Hotel promotes a sense of community through shared spaces. The hotel, restaurant, and spa are designed to encourage social gatherings and interaction among visitors. A detail worth noting is the green roof system, which helps the building blend into its surroundings and supports local wildlife.

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.
