b+ (bplus.xyz), formerly brandlhuber+, is a collaborative architecture practice operating at the intersection of theory and practice through various media and formats. The practice engages with contemporary challenges, especially the social-ecological transformation of existing buildings, offering economically viable solutions.
The studio understands architecture as an open process, viewing buildings as part of larger systems that require systemic approaches. It considers existing buildings and legislation as active design tools with transformative potential. Thus, b+ celebrates the existing built environment and aims to reveal latent potentials within.
The practice emphasizes collaboration with different actors and stakeholders, valuing their expertise and creating spaces for exchange. b+ seeks to advance a new value system in architecture focused on collective responsibility, systemic thinking, and ecological and economic viability.

2025 Biennial Project

Project Overview

Terrassenhaus/LoBe Block

Terrassenhaus Berlin/LoBe Block is a ziggurat-shaped complex of studios and galleries with broad, semi-public terraces. Built under unique zoning rules—including a 1958 regulation that allows only commercial buildings, a grandfather clause preserving the area’s residential character, and no binding land-use plan—the project functions as a commercial space today but can be converted to residential use in the future. Floor-to-ceiling doors open directly onto the terraces, while the interiors remain purposefully undefined.
