There are buildings that shelter, buildings that impress, and, rarely, buildings that teach. The Museum of Solutions — MuSo — belongs to the last category. Commissioned by the JSW Foundation and designed by Bricolage Bombay under the leadership of Vinit Nikumbh, MuSo is India’s first children’s museum dedicated to the United Nations’ Sustainable Development Goals. It is housed in a purpose-designed structure of approximately one hundred thousand square feet in Lower Parel, Mumbai — a neighbourhood that has, over the past three decades, transformed itself from a graveyard of dying textile mills into the cultural and commercial centre of the city’s aspirations. MuSo stands at the apex of that transformation: a LEED-certified building that makes the argument, in concrete and steel and glass, that architecture itself can be a pedagogical instrument.

The site presented immediate challenges. Located on a dense urban parcel closely flanked by heritage mill buildings, the structure had to be efficient in its footprint while generous in its interior volumes. Bricolage Bombay’s structural response was a hybrid system: forty percent concrete core providing stability and lateral resistance, sixty percent steel framing giving the building its open, adaptable floor plates. This combination allowed the architects to maximise usable area on each level without compromising the structural integrity demanded by a building that will welcome millions of young visitors over its lifetime. The floor plates are intentionally flexible — designed so that exhibits can be reconfigured as themes and educational programmes evolve over coming decades.

Inclusivity is embedded in the architecture from the foundation upward. The building’s vertical circulation is organised to be fully accessible: ramps and lifts are not afterthoughts or compliance gestures but primary routes through the building, sized and lit with the same generosity as the staircases. Wide corridors accommodate the unpredictable spatial patterns of children — the sprinting, the stopping, the turning in tight circles — while the double-height lobby creates an arrival moment of genuine civic grandeur. Walking into MuSo for the first time, whether you are six years old or sixty, you feel that something important is happening here.

The building’s services — ducts, pipes, conduits, structural members — are left deliberately exposed at child eye level. This is not an aesthetic accident; it is a design decision rooted in educational philosophy. If MuSo’s mission is to demystify the world for children, then the building itself must begin that demystification. A child who can see how a building breathes and carries its loads is a child who understands that the built world is not magic — it is engineering, it is material, it is human decision-making made physical. This ethic of visible making runs through every layer of the project, from the structure to the exhibit cases.

The facade is one of the building’s most expressive elements. Designed to communicate dynamically with the street, it reads differently at different times of day. In daylight, the glass and metal skin is transparent, showing glimpses of the activity within — a perforated veil rather than a barrier. As darkness falls, the building transforms: internal lighting turns the facade into a luminous white box, a radiating advertisement for the ideas nurtured inside. This day-night duality is not theatrical contrivance but a considered response to the urban context. Lower Parel is a neighbourhood of office workers, residents, restaurant-goers, and commuters. The building’s night face is a beacon for all of them — a reminder that the museum exists, that it is open, that it belongs to the city.

The interior is organised around a sequence of distinct but interconnected floors, each housing a different learning environment. The ground floor anchors the civic relationship with the street: the lobby, the Subko café, the information desk, and the entry to the Play Lab. Upper floors house the Make Lab — where children fabricate, code, and engineer — and the Discover Lab — where interactive exhibits explore global sustainability challenges through the lens of water, forests, and the commons. The programming, developed by the JSW Foundation’s curatorial team alongside content specialists, guided the spatial organisation at every level. Architecture followed content, not the reverse.

Bricolage Bombay’s involvement at MuSo began years before the main building was designed, through the experimental prototype MuSo Mini — a full-scale proof-of-concept installed in a two-bedroom apartment in Worli. MuSo Mini allowed the team to test programming, aesthetic assumptions, lighting, furniture proportions, and children’s behavioural responses in a low-cost, low-risk environment. Many of the decisions embedded in the final building — about colour, about material, about the relationship between open and enclosed space — were first discovered and refined in that small apartment. It is a model for how serious, resource-conscious design research should work: prototype before you build, test before you commit, learn before you spend.

The Museum of Solutions has, since its opening, established itself as one of India’s most significant new cultural institutions. It has been celebrated by educators, urban designers, and cultural commentators as evidence that Indian philanthropy, when combined with serious architectural and curatorial ambition, can produce institutions of international quality. For Bricolage Bombay, MuSo is not merely the largest project in the portfolio — it is the fullest expression of the studio’s conviction that design, at its best, changes the way people understand the world.
