A parabolic light channel floods the communal spaces with natural light, while the combination of concrete and timber emphasizes warmth and sustainability in a guesthouse designed for tea manufacturing and community living.
5 key facts about this project
01
A parabolic light channel enhances natural illumination in communal areas.
02
The building retains the original barn structure, maintaining cultural heritage.
03
Dual-function ovens serve as heating sources and communal gathering points.
04
A greenhouse wall allows for herb cultivation and encourages natural ventilation.
05
Timber and concrete materials create a balance of warmth and durability.

The Ozolini Guest House is located in a region characterized by long and cold Baltic winters. The design combines the preservation of historical structures with contemporary living needs. Inspired by traditional Baltic farmhouses, known as namas, the building features a functional layout that accommodates tea manufacturing on the ground floor and living spaces above. The existing barn is retained in its original state, allowing for a respectful integration of past and present.

Architectural Concept

The layout reflects a strong focus on functionality and community interaction. A central feature is the dual-function oven system, akin to traditional black kitchens. This system serves as both a source of heat and a gathering point for residents, fostering social connections within the space. The central block greatly enhances thermal efficiency while also encouraging communal engagement among those who inhabit the guest house.

Materiality

Concrete and timber are the primary materials used throughout the structure. Concrete provides necessary support and durability, while timber adds warmth and texture to the interior. The relationship between the two materials enhances the overall design and improves the building's energy performance. This thoughtful material selection enriches the experience of those who live and work in the space.

Natural Light and Ventilation

Natural light and ventilation are integral aspects of the design. A parabolic light channel allows daylight to fill communal areas, creating a bright and inviting atmosphere. The greenhouse wall also plays a crucial role, allowing fresh air to circulate. It enables the growth of herbs while seamlessly connecting the interior to the outdoors. This feature promotes a sense of well-being and fosters a connection to nature.

Spatial Dynamics

The design carefully balances public and private spaces to meet varying needs. Flexible partitions allow for adjustments in how spaces are used throughout the day. Curtains create fluid transitions between work areas and living quarters, offering privacy when necessary. This adaptability demonstrates a responsive approach to modern living within a rural context.

Natural light flows into the building through thoughtful window placement. The shifting light throughout the day adds to the experience. It creates a dynamic environment that evolves with the sun's path, inviting residents to engage with their surroundings in different ways.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
