Je recommande vivement le bureau Alexis Müller Architecte pour ses services compétents, efficaces et professionnels. M. Müller est parfaitement à l'écoute des besoins du MO, est capable de s'adapter à des contraintes complexes comme la rénovation d'un bâtiment classé, et connaît très bien les normes et exigences pour des projets élaborés. Il est réactif, présent et de bon conseil, et propose des solutions cohérentes et esthétiquement bien intégrées. La gestion et la direction technique sont bien maîtrisées et le cadre contractuel avec les entreprises très claires. Tout cela, avec sourire, humour et décontraction.
