Z33 settles in continuity with the existing buildings around the béguinage, echoing the dual character of their facades, enclosed towards the street and open with windows’ filigrees towards the garden. The exhibition rooms and the secret gardens compose a spatial labyrinth, amalgaming memories of local passages with ones of foreign villas or palaces. Hasselt béguinage is alike a city in the city. The garden is enclosed by a wall of heterogeneous brick buildings, a place of rest. Z33 is part of this continuous border, as one building made of two: the 1958 existing museum and its extension. Alike the other buildings surrounding the garden, the extension building disposes a long and almost blind brick wall towards the street, echoing Roman opus reticolatum, and displays a score of windows towards the garden. The new wing interior scenography alternates rooms and gardens, offering a plurality of views and parcours similarly to what happens in a city; here rooms are specific in size, proportion and natural lighting, different from the existing wing classical setting, which has been appropriated as an ideal “white cube”. The slender section of the thresholds between spaces do not reveal the real thickness of the walls, so that rooms belong one to another. The process begun from observing the “cultural structure” of the place, meaning the permanencies that cannot be ascribed to a language or a form, though express the relationships between human constructions and a topography and among the constructions themselves. They seem to result from building gestures being repeated over centuries. Hence the strategy was simple: to build in continuity with the cultural structure of Hasselt béguinage, though with a different language and different material means. The process started much earlier than the competition, making converge public actors in a common vision. The international competition was in three steps: 1st screening the teams economical and professional profile; 2nd presenting a text - no design yet - stating the attitude towards the historical context, the space for art and the process management; 3rd the design proposal. We proposed very early a radical redistribution of the budget, combining conventional ways of building with experimental ones. Two public tenders followed, with low budget. The awarded contractor started in June 2017 and ended in November 2019: 365 working days, within time and budget frames. The budget for this ambitious public assignment was low - 7 million € for 4600 sqm (approx. 1500 €/sqm). So from the early stage of the competition, we proposed a screening of architectural details in scale 1:20 and of the installations arrangement strategies. Clay, concrete, lime are all local materials with whom builders are familiar. The new building is a simple concrete structure with non-exceptional spans, where experimentation is specifically and punctually chosen: the jointless load baring masonry façade, one cast in situ lacunar ceiling (beams section between 4-15 cm, height 160 cm), the cast in situ diamond ceiling and the integrated displaced ventilation. All non-conventional details have been developed during definitive design phase as preparation for the public tender. The façade is the most significant example and it can be shortly described as a reinforced layered solid masonry wall, jointless and without cavity so that a brick wall may sound as a full one. 3 years of study, 68 brick colour tests, 20 mortar tests, 103 brick types, 34.000 bricks, 5 mm displacement, 3 mm tolerance, 2 man making bricks, 5 man building façade, (almost) infinite drawings.
