IB Studio works primarily on the rehabilitation of country homes, farmhouses, mountain chalets, beach houses and urban apartments



It all began in 1980 when Isabella Invernizzi, after graduating in Architecture from the Milan Polytechnic and collaborating with Marco Zanuso, opened IIAW – Isabella Invernizzi Architecture Workshop. The firm, based in Milan, specialized in prestigious renovations and over the years also a significant number of international projects were completed. 

In 2009 Beatrice Bonzanigo graduated from the Academy of Architecture of Mendrisio (CH), joined the firm and contributed to the development of a humanistic design culture inspired by the philosophy pursued by her mentoring architects: Peter Zumthor, Valerio Olgiati, Manuel and Francisco Aires Mateus and Mario Botta. 

IB Studio was opened in 2014. From the elegant apartments in the city centre, to the farmhouses in the Tuscan countryside and from the villas on the Riviera to the chalets at the foot of Mont Blanc, IB Studio’s design language is never limited to simple philological recovery, but aims to a functional and aesthetic improvement of the buildings.
IB Studio’s portfolio also includes other types of projects, such as a hotel in the Umbria region, a chain of restaurants in Japan, a villa in Australia and a winery in the Tuscany region, for which the firm was awarded the prestigious American Architecture Prize in 2016.

IB Studio participated in several installations of exhibitions, including one at the Venice Architecture Biennale in 2018, one at MADD – Musée des Arts Décoratifs et du Design in Bordeaux in 2019 and for MK Gallery in London in 2020.

For the project Casa Ojalá the Firm has been awarded with the international prizes Gold A' Architecture, Building and Structure Design Award, 2019 and AHEAD EUROPE & GLOBAL AWARD in hospitality in 2021..

IB Studio received a nomination as “Best Country Home Renovation Firm 2019 – Italy” from the English magazine BUILD and “Best of Houzz Design 2019, 2020, 2021” from the global leading online home renovation and design platform Houzz and recently received the prestigious prize “Luxury Lifestyle Awards 2022.”

In recent years, Isabella and Beatrice expanded their activities to the USA, Latin America and Taiwan.
