英國(guó)二級(jí)保護(hù)建筑漢諾威大樓的改造是對(duì)一座維多利亞時(shí)期庫(kù)房的翻新及屋頂?shù)臄U(kuò)建。

漢諾威大樓位于布拉德福德的小德國(guó)區(qū)，那是一個(gè)歷史價(jià)值很高、美輪美奐的保護(hù)區(qū)。這個(gè)地區(qū)獨(dú)到的特色源自風(fēng)格統(tǒng)一的19世紀(jì)建筑。

所用的砂巖和立面的裝飾將街區(qū)統(tǒng)一起來(lái)——盡管與許多其他同時(shí)代的半工業(yè)區(qū)一樣，小德國(guó)區(qū)的建筑大小和形式各不相同。因此，屋頂?shù)木坝^(guān)也是豐富多樣的。

這就為新屋頂?shù)脑O(shè)計(jì)帶來(lái)了靈感，并對(duì)周?chē)慕ㄖ问?、大小和朝向作出新的闡釋。

屋頂輪廓的雕刻特征并非只是一場(chǎng)建筑幻想，而是與周邊建筑的屋頂景觀(guān)相映成趣，并構(gòu)成了生活的空間。

為了建造一個(gè)高效的結(jié)構(gòu)，這個(gè)屋頂被設(shè)計(jì)成一個(gè)自承重體系，避免給現(xiàn)有的樓板增加荷載。我們用人造木板作為可持續(xù)的高性能材料，以外墻為支撐創(chuàng)造出一個(gè)反復(fù)折疊的屋面。

屋頂折射出主體的結(jié)構(gòu)、日照方向和各種景象。

進(jìn)深15m的樓層平面需要精心設(shè)計(jì)的方案，以避免出現(xiàn)梁架過(guò)大的低效屋頂結(jié)構(gòu)。所以屋面是順著折板反復(fù)折疊的，這樣就形成了一個(gè)以外墻為支撐的自承重結(jié)構(gòu)。在高處，屋頂?shù)某兄攸c(diǎn)深入建筑內(nèi)部，將結(jié)構(gòu)的跨度從15m縮短到10m。傾斜的陽(yáng)臺(tái)側(cè)墻將這些點(diǎn)上的反作用力傳到外墻上。任何形成的側(cè)向力都被傳導(dǎo)在起拉結(jié)作用的樓板上。

屋面由交錯(cuò)層壓人造木板制成。140mm厚的木板傳熱系數(shù)很好，構(gòu)成了保溫良好的屋頂。

所選的屋頂掛板用現(xiàn)代材料對(duì)街區(qū)傳統(tǒng)的石板瓦屋頂進(jìn)行了新的闡釋。新屋頂采用無(wú)煙煤預(yù)銹化立縫鋅掛板，外觀(guān)與原屋頂相似。這個(gè)復(fù)雜的屋頂造型包括各種屋脊和天溝、斜墻、折面、曲面和輻射狀轉(zhuǎn)角。這就需要一種能夠滿(mǎn)足這些條件的施工技術(shù)。立縫鋅屋頂是克服這一難題的最佳方案。

其空間概念已融入施工和結(jié)構(gòu)，并構(gòu)成了一個(gè)整體?！酰ㄉ袝x 譯）

The development of the grade II listed Hanover House involves the refurbishment and roof extension of a Victorian warehouse building.

Hanover House is located in Bradford's Little Germany, a conservation area of great historical interest and beauty. The unique character of the area is created by the uniformity of buildings dating from the 19th century.

The used sandstone material and the ornamental treatment of the facades unify the blocks - although, as with many other semiindustrial areas from the period, the buildings in Little Germany vary in size and form. Accordingly,the roofscape is one of great diversity.

This informs the design of the new roof, which reinterprets the surrounding forms, sizes and orientations.

The sculptural aspect of the roof silhouette is no mere architectural fancy, but ref l ects the roofscape of the surrounding buildings and has been used to form the living spaces.

Aiming to create a highly efficient structure, the roof has been designed as a self-supporting system to avoid additional loading onto the existing floors.We used engineered timber as a sustainable highperformance material, creating a roof surface which folds up and down and bears on the external walls.

The roof form reflects the construction of the primary structure, daylight direction and views.

The deep floor plan of 15m required an engineered solution to avoid an inefficient roof structure with oversized beams. Therefore the roof surface folds up and down to a folded plate creating a self supporting structure, which bears on the external walls. At high level the load bearing points of the roof are taken further into the building in order to shorten the span of the structure from 15m to 10m. The inclined balcony side walls transfer the reaction forces at these points into the external wall.Any resulting lateral forces are transferred into the floor plate which acts as a tie.

The roof surface is made of cross laminated engineered timber boards. The 140mm thick board has a good value and adds up to a highly insulated roof.

The chosen roof cladding re-interprets the traditional slate tiled roofs of the neighbourhood with a modern material. Similar in appearance the new roof is clad in anthracite pre-patinated standing seam zinc. The complex roof geometry with various ridges and valleys, inclined walls, folds, bends and radiused corners required a construction technique to accommodate these conditions. The standing seam zinc roof was an optimal solution for this challenge.

The spatial concept has merged with the construction and structure and has formed one entity. □
