In the landscape of contemporary architecture—where technical innovation coexists with environmental urgency—the studio Alventosa Morell Arquitectes stands out with clarity. Founded in 2012 by Marc Alventosa Zaidín and Xavier Morell Jané, and based in Barcelona and Lleida, the practice has made sustainability a fundamental principle—the true DNA of the way it conceives architecture.
Their architectural practice is grounded in a firm conviction: architecture must respond to climate, landscape and people with solutions that, through sensibility and beauty, ensure comfort, efficiency and environmental respect. This is not about adding a “green” layer to construction, but about designing projects that are born already integrated into a natural balance.
A methodology that listens to place
Each project begins with a gesture of attention: observing the territory, reading the topography, studying the sun, the wind, the shadows. From this initial dialogue emerges a design that combines passive strategies, noble materials and responsible construction systems. Handmade ceramic brick, certified timber or natural insulation coexist with technical innovations that make it possible to reduce energy consumption by more than 70% compared to a conventional dwelling.
Intermediate spaces—porches, courtyards, pergolas—become true climatic refuges, places of transition where architecture reveals its ability to soften the seasons and celebrate everyday life.
Projects that become manifestos
From their hands have emerged homes that are almost manifestos of a new way of inhabiting. Casa GJ in Matadepera (Barcelona) unfolds through nine south-facing structural modules that connect interior and exterior. MM House in Valldoreix (Barcelona) recovers and transforms a 1947 home, combining thermal mass and natural light in a dialogue between memory and future. LA House in Llinars del Vallès (Barcelona) explores the honesty of traditional materials to achieve low energy consumption standards. And Casa CG in Creixell (Tarragona) distils their philosophy into two words: resource optimisation.
Each project reaffirms their commitment to an architecture in which excess has no place—only precision, restraint and environmental generosity.
Their work has been recognised with national and international awards such as the 2025 Architizer AA+Awards, 2024 DNA Paris, 2024 Architizer Awards, 2024 ArchDaily Awards, 2023 4 Future Awards, 2023 Dezeen Awards, the 2022 Mapei Award for Sustainable Architecture and the 2019 BUILD Architecture Award. These distinctions underline that their approach resonates not only with clients and users, but also with specialised critics.
Marc Alventosa, the son of an architect, grew up among drawings and construction sites, learning to observe spaces with the patience of someone who knows how to listen. His sensitivity leads him to reflect on nearly zero-energy buildings as an urgent necessity in the face of climate change.
Xavier Morell, whose career has been shaped by both public and private projects, contributes a broad vision that integrates rehabilitation, industrialisation and research into materials as part of the natural evolution of contemporary architecture.
Together they form a balanced partnership, in which creativity and technique complement one another to give life to a studio whose work is recognised above all for its ethical commitment.
