Small is beautiful (+ energy efficient) – compact 140 sqm private house with outstanding ‘sustainability credentials’.

Plastered monolithic insulating ‘Poroton’ brick walls, triple glazing and a deep bore heat exchange pump lead to a non-fossil fuel energy classification (KFW 70) – 30 per cent below the current energy regulation.

MONTELUCE MASTERPLAN

On 12th sept. 2006 the office of Bolles+Wilson was awarded the first prize in the International Design Competition for Monteluce in Perugia.

The jury lead by Axel Sowa, director of “Architecture d’ aujourd’hui” commended the winning entry for its respect and sensitivity to the scale of Monteluce, its morphological compatibility with the historic structure of Perugia and its sympathetic relationship to the surrounding Umbrian landscape.

The Convento delle Clarisse of S. Maria di Monteluce originating in 1218 stands outside the Etruscan walls of Perugia, an outpost protecting one of the main access roads. Expansion outside the medieval walls reached Monteluce at the end of the nineteenth century. A concurrent appropriation of religious assets by the State instigated the opening of a gate to the Piazza Monteluce and between 1910 and 1923 the construction in the monastery garden of a series of hospital pavilions.

The Competition Program developed in close co-operation with the Commune di Perugia called for a total of 65,000 sqm – 43% of which is student and private housing and 25% subsidised housing. The new urban Quartier is networked in terms of a continuity of urban spaces and a rich programmatic mix including a maximum of 10% retail and 5% office use as well as hotel and conference facilities, local health offices, kindergarten and a new public park.

The Bolles+Wilson design developed and presented in 1:500 model format rejects authoritative geometry in favour of a sequencing of localised responses tailored to the dramatic topology and framed views out and across the luxurious Umbrian landscape. For economy and continuity many new structures occupy the footprint of redundant hospital buildings, a strategy that preserves the extensive terraced system of retaining walls and protected trees.

Bolles+Wilson describe their scheme as Urban Choreography, a sequence of public spaces unfolding from the S.Maria di Monteluce church in the west to the new Park d’Este. A first Piazza is framed by the Monestry portico and the one remaining Hospital Pavilion (Public Health Offices). To the north are offices and a submerged supermarket. To the south a Hotel and Conference Pavilion frame the view in the direction of Assisi. A second Conical Piazza is enclosed by a row of student housing buildings to the north and an opposing commercial/ restaurant Acropolis. Here deck- like upper terraces offer spectacular views of the historic skyline and Umbrian landscape.

MONTELUCE QUATTRO

The core of the new urban quarter became the (architectural) responsibility of BOLLES+WILSON (see siteplan). In realization it follows very closely the competition proposal of two Piazzas on the crest of the hill/ridge, underneath these two levels of carparking ensure car free public spaces (500 cars disappear underground). The strategic placement of these two Piazzas follows the typical Perugian trope of leaving one side of a space open for cooling winds and views out across the sensuous and gently rolling Umbrian landscape (views across the valley to Assisi).

The strategy of two piazzas introduces a spatial sequence resulting from the integration of the historic monastery and the12^th century chapel – their arched entrance portal announces the entry to the first new Piazza, now named Piazza Cecilia Coppoli (1426-1500, poetess and humanist) and opened on 19^th March 2015 by Catiusca Marini – President of the Region of Umbria. Signora Marini described the Monteluce spaces as ‘an investment in the culture of the city, also in the public patrimony of Perugia, an exemplary work and graceful urban transformation, one that experiments with a new contemporary urban architecture.’

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’.

The Cinnamon tower was conceived as freestanding campanile – a pin on a piazza was the concept behind the premiated competition design by BOLLES+WILSON for the existing 19th century Harbour Masters Building.

A tower was not anticipated in the competition programme, but the jury agreed that a tower anchors the public functions around the only remaining historical building to survive between the megablocks of the ‘Overseas Quarter’ master plan. The historic building will also be more autonomous.

Slenderness is essential for a campanile. Over the course of its 8-year gestation this was respected – even while its function mutated from stacked restaurants to housing. The 13 x 16 m floor plan tapers towards the top. With a height of 56 meters the tower is 4-times higher than it is wide.

How can such a thin chap be efficient?
The efficient answer is duplex apartments. Originally the concept foresaw seven apartments, each on 2 floors, a panoramic living deck on the upper level and bedrooms with punched windows below. Precise market analysis led to a variation of this formula: one triplex apartment at the top and some 1-floor apartments at lower levels. Built were ten apartments, four with 130 sqm, five with 185 sqm and one with 300 sqm. The tower has a gross floor area of 4.300 sqm and a volume of 16.000 cubic metres. At the ground level, the piazza level is a commercial area of around 300 sqm.

Strict high-rise regulations demanded an escape route from every floor via secured escape stair. The possibility to clean every window from the inside was also a criterion to be met. The spectacular view of the New Elbphilharmonie should not be blurred by dirty windows. Room-high windows on three sides of the living room also allow the tracking of incoming cruise ships.

Facade panels of anodized aluminium sheets in different gradations of dark red correspond to the patchwork of BOLLES+WILSON’s pavilion from 2008. This was the first realized component of the Harbour Masters ensemble. In sunlight these aluminium panels take on colourful nuances while on cloudy days they assume a darker, more serious Paul-Klee like appearance. This is a building that changes its character according to the incidence of light, a new figure on Hamburg’s skyline.
