A solar greenhouse integrates with a cross-laminated timber house, providing flexible living spaces and an art workshop that seamlessly connects to the serene lakeside environment.
5 key facts about this project
01
A solar greenhouse acts as a communal space and captures winter sunlight.
02
Cross-laminated timber panels provide structural integrity and promote sustainability.
03
Glazed walls enhance natural light and connect interiors visually with the lake.
04
Flexible workspaces in the art workshop allow for both collaboration and privacy.
05
Protected basements accommodate local bat habitats, supporting biodiversity.

The redevelopment of a lakeside site focuses on creating a painters' house and workshop that harmonize with the natural surroundings while addressing user needs. This project retains the existing structures’ footprints, which will be demolished and replaced by new buildings. The design concept emphasizes lake views and integrates functional spaces to enhance the overall experience.

Design Concept

The design prioritizes several essential elements: respect for the natural environment, an emphasis on views of the lake, the use of renewable energy, and the provision of flexible living and working arrangements. A walkway connects the new structures, providing easy access to the lake while considering local wildlife, such as having protected areas in the basements for bat populations. This pathway not only links the project site to the main road but also ensures year-round accessibility.

Spatial Organization

The layout of the painters' house consists of two apartments, each with two bedrooms located on the ground floor. The upper level is dedicated to living and kitchen spaces, designed to maximize the experience of lake views. A communal area sits between the two residences, surrounded by large glazed walls that allow sunlight to enter, turning it into a usable solar greenhouse during the winter months.

Workshop Integration

The design of the painters' workshop centers on flexibility, accommodating the diverse needs of the artists. Adaptable spaces within the workshop can be configured for communal events or separated into smaller rooms for individual projects through movable curtains. This versatility allows for both social interaction among artists and spaces for focused work.

Materiality and Sustainability

Drawing elements from Latvian vernacular architecture, the design features ground floor cladding that resembles traditional stone basements, while the upper portions incorporate modern wooden cladding. The main structure utilizes laminated wood and cross-laminated timber walls. The roof is made of sheet metal, contributing to the durability of the buildings. Renewable energy systems, including wind turbines, are included, emphasizing a commitment to sustainability and enhancing the connection to the surrounding environment.

Large glazed walls in the communal area serve practical purposes while providing abundant natural light. This design decision enhances the indoor experience, allowing occupants to engage with the seasonal changes outside and the calming presence of the lake.

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.
