The 1992 Kita 102 in Frankfurt – Griesheim was one of BOLLES+WILSON’s first buildings in Germany. 22 years later it has been extended. What does it mean to revisit an early work? To measure if it has stood the test of time? Or even if the architectural themes of that time are still pertinent today?

What is immediately obvious is that a generous two floor, curvaceous and somewhat expressive sculpted volume is no longer feasible under today’s stringent budget restrictions (the political promise to deliver a kindergarten place for every child). The new extension is single storey, docking on to and sloping down from, an original 7 m high sport and sleeping hall.

The 3 original ground floor classrooms were for conventional pre-school kindergarten use, and the upper 2 rooms after-school homework facilities for older kids. The 3 new ground level classrooms extend kindergarten functions, kids can run out directly from group to garden.

The original building expands in width and height, a conical volume explained at the time as a metaphor for growing – spaces expand and contract as kids run from one end to another. A narrative scenario that extended to details like 2.10m high doors for teachers beside 1.50 m doors only for kids. Draconian budgets preclude such whimsical game playing in the new extension, perhaps it is also no longer the time for architecture to reflect on its syntactical potential. In the original Kita four windows conspired to inscribe a giant letter K across the facade. A readable building for children who are learning to read. Today it is left to colour to signify. A thematized May-Green has been here co-opted (as in almost every second contemporary Kindergarten) to signal a fresh, playful optimism. It is the only internal colour. Also a green horizontal beam/gutter above a south facing glass facade benevolently grows extended sun-blinds (also May green) to wrap the sunny side in a Mediterranean-like slab of shade. Window articulation is no longer expressive, a tough neighbourhood requires defensive measures if night cooling is to be activated.

What was in 1993 described, as an east-west slab turning its back to the noise of a nearby autobahn is now a very long east west slab, still turning its back and opening southward to an extended linear play-ground.

An observation Tower connects an archaeological dig to its wider landscape. Nearby the Corten clad visitors centre with its cargo of sky disk (4,000 years old sky map) paraphernalia wriggles a few metres above rolling fields casting at its extremity a laconic glance skywards.

Finished in late 2020 Frobenstraße 1 offers for renting 11 variously sized apartments and 2 commercial units in an area of fashionable shops and galleries (Potsdamer Straße), street prostitution, social housing and huge investor driven developments of owner occupied apartments.

Frobenstraße 1 is a chorus member. It is not a Primadonna that steps out to front stage. The choreography of urban choruses is the Großstadt-DNA of Berlin, Paris or Barcelona. It defines the street line and the eaves line. In Frobenstraße 1 the upper facade limit is articulated with a recessed shadow line, a modest but significant detail.

The well behaved chorus anticipates a fictive future block-perimeter conclusion to the south, where there is now a Kindergarten with luxurious trees. Here the pink side wall (fire wall) presents itself for the kids with its giant footprint graphic.

Unlike the Bel étage of a Paris House the first floor here has the standard 3,10 m room height, but its special relation to the street is prescribed by the delicate and continuous railing.

The window composition to the street describes the internal layout where three apartments break out of the standard, but generous room height to 4,80 m and 6,50 m. The grey facade has therefore aspirations to be read as a palazzo, with the projecting penthouse window playing the classic attica.

The garden facade is more domestic, balconies meandering out for afternoon sun and individual planting.

For the interior communal stair and lift black and white tiles dignify homecoming.

The anatomy of redundant bus and tram workshop/sheds was co-opted as the organising template for this 1999 premiated Quartier Masterplan. An east west piazza focusses the networked block interior.

The principles of the Masterplan were: The ‘loftising’ of one workshop shed, a brick administration building which grows into penthouses and bus garage doors which envelope row-houses.

Southward from the piazza a spatial choreography of Office Slab and Housing Tower leads over a raised terrace with a second (zigzag) office facade, past a café/bar, down an Eisenstein stair to street and canal. This perspectival sequence – an opening and closing of large scale urban rooms – is homogenised by its rich and tactile material, a ‘Hamburg-solid turf-fired brick’.
