There is a new sports field at the unlikely location of E Pike and Bellevue. Look up.

Monday morning, the 6th through 12th graders at Capitol Hill’s Northwest School explored their new 38,300 square-foot facility at 401 E Pike that somehow houses “a league-size Gymnasium, 175-seat Black Box Theatre, two-tiered Dining Room, and a 6,000 square foot Rooftop Sports Field.”

“We used every inch from basement to roof,” Head of School Mike McGill told CHS as he watched students take their first kicks on the new rooftop turf and cork pellet field.

500 students currently attend classes at Northwest including 50 in the school’s international boarding program, the only one of its kind in Seattle.

The $19 million project designed by Mithun is one of a wave of big-money construction projects planned and underway for the doing very well, thank you roster of private schools on Capitol Hill. The Northwest project broke ground in September 2012 and was completed ahead of schedule and slightly under budget thanks to incentives for contractor Exxel Pacific to bring the job in on time.

Developer HFZ Capital picked up the iconic Chatsworth apartments at 340 West 72nd Street for a cool $150 million in 2012 and announced plans for a penthouse addition in October. Yesterday, representatives for the developer shared with the Landmarks Preservation Commission the plans by Montroy Anderson Demarco for two new floors atop the main building of the 1904 Beaux Arts structure and one extra floor on its annex building next door. But the team pushing for the rooftop additions, an external facelift for the façade, 24 new windows, and extra entrances could only sit and watch in silence as a dozen community members and preservation advocates bashed the design and representatives for three elected officials registered their bosses’ disapproval. The commissioners pointed out that it’s even more difficult to get approval for work on an individually landmarked building. “That really says to me that we need to scrutinize any changes more carefully,” said Commissioner Elizabeth Ryan of that designation.

Elevated park at trade center site comes into view

The World Trade Center’s best-kept secret has finally come to light.

It is an elevated park, slightly larger than an acre and 25 feet above Liberty Street, that will command a panoramic view of the National September 11 Memorial when it opens to the public, probably in 2015.

Liberty Park, as it is called, is meant to offer a pleasant and accessible east-west crossing between the financial district and Battery Park City; to create a landscaped forecourt for the new St. Nicholas Greek Orthodox Church; to provide a gathering space for as many as 750 people at a time; to allow visitors to contemplate the whole memorial in a single sweeping glance from treetop level; and to serve as the roof of the trade center’s vehicle security center.

For the moment, the park is an empty concrete expanse. The pedestrian bridge over West Street that will connect it to Battery Park City — the bridge that survived the Sept. 11 attack — currently falls several yards short of its future landing spot.

While the general outlines of the park have been known for years, the Port Authority of New York and New Jersey has been sparing in its public discussion of the project, in part because not every detail of its design and construction has been settled.

But the Port Authority’s hand was forced somewhat last month when sumptuous images of St. Nicholas Church and Liberty Park appeared on the website of the architect Santiago Calatrava, who is designing the church. The park was rendered in sufficient detail that it was possible for the first time to understand its basic design. […]

Des étages en plus pour créer des logements

Paris ne peut pas s’étendre indéfiniment, il doit se réinventer à l’intérieur de ses propres limites. Et si la solution se trouvait sur les toits?

Il faut débloquer le foncier», a asséné Nathalie Kosciusko-Morizet, ministre de l’Ecologie et du Logement, jeudi 2 février, sur les ondes de France Inter, après avoir commenté la mesure annoncée dimanche par Nicolas Sarkozy d’augmenter de 30% le coefficient d’occupation des sols (COS); selon elle, avec cette décision «la constructibilité augmente partout [y compris] les limites de hauteur, les limites de gabarit. (…) Ce n’est pas de l’étalement urbain, c’est tout le contraire».

Avec une des densités les plus élevées au monde (près de 22.000 hab/km contre seulement 13.500 pour Tokyo et près de 11.000 pour New York), Paris suffoque, ceinturé par un périphérique et un habitat de banlieue qui n’attire pas les jeunes urbains.

On crée pour l’instant 40.000 logements par an à Paris et le programme du Grand Paris projette d’en construire 70.000.

L’extension horizontale de la ville n’est plus une solution viable. Mais comment absorber la population parisienne de plus de 2.200.000 habitants tout en préservant la qualité de vie? Comment faire face à la pénurie des sols?

‘Innovative’ housing with rooftop farms set for southside

City zoning board members approved a 77-unit mixed-use housing development near downtown Berkeley late last week, expressing excitement about a “unique” design set to include more than a dozen working rooftop farm plots and a novel approach to parking.

“Garden Village,” at 2201 Dwight Way at Fulton Street, brings with it a number of innovative features, from its composition — it’s made up of 18 distinct but connected “volumes,” or towers, that range in height from 3 to 5 stories and are connected by open-air walkways; its more than 12,000 square feet of rooftop farming plots; and its small garage, which offers just enough space for a fleet of shared vehicles that will be rentable by tenants.

Without the car-sharing idea, the project would have required room for 71 vehicles. Instead, Berkeley-based developer Nautilus Group decided it would purchase a fleet of four to 10 automobiles and contract with a car-sharing operator called Getaround to run the “car-share pod” operation. (The city required Nautilus to pay for a parking demand study to bolster the justification for that approach.)

Zoning board Commissioner Shoshana O’Keefe described the concept as potentially “genius,” adding that the notion of projects that fold effective car-sharing programs into their plans “might be the magic solution” to the hairy issue of meeting parking demand efficiently in a densely-populated community.

« Dans l’avenir, il n’y aura plus d’immeubles tertiaires sans une réflexion préalable spécifique sur la végétalisation »

Alors que se tient à Nantes jusqu’au 13 septembre le Congrès mondial de la végétalisation du bâtiment (World Green Infrastructure Congress), LeMoniteur.fr a interrogé Stéphane Carpier, Directeur technique Développement durable et innovation de Gecina. La foncière a fait depuis quelques années de la végétalisation un élément incontournable de ses projets immobiliers.

Qui est le premier prescripteur de végétalisation sur les projets de Gecina ?

Stéphane Carpier : Gecina s’est lancée dans la végétalisation depuis quelques années déjà. Et tous les cas de figure existent.

A Boulogne-Billancourt par exemple, l’aménageur, la SAEM Val de Seine Aménagement avait expressément requis des toitures végétalisées. On a donc réalisé les premières toitures pour les immeubles Khapa (Foster+Partners, Ateliers 234) et l’Angle (Jean-Paul Viguier) (2008-2009). L’aménageur voulait pour ces bâtiments une sorte de « cinquième façade ». Sur ces toitures, nous avons opté pour une végétalisation « extensive ».

Pour l’immeuble Anthos (Naud et Poux), le végétal est entré dans la conception du bâtiment : la toiture se retourne en façade (mur pignon) et devient un mur végétalisé. La demande de l’aménageur est devenue une idée architecturale. Dans ce cas précis, Gecina a accompagné le projet, à l’époque le plus grand mur végétalisé d’Europe pour un immeuble de bureaux.
