項(xiàng)目的任務(wù)是提高一處1950年代住宅區(qū)的密度。建筑位于城市邊緣，環(huán)境優(yōu)美。改造將以當(dāng)代方式對(duì)原有住宅樓進(jìn)行修整，并保留其原始?xì)v史特征，同時(shí)更新供能基礎(chǔ)設(shè)施。

為保留居住區(qū)的開(kāi)放性，決定向上增加若干層，提高原建筑的高度。項(xiàng)目的設(shè)計(jì)條件要求更新供能基礎(chǔ)設(shè)施，并延續(xù)居住區(qū)原有的建筑和構(gòu)造特征，同時(shí)新增樓層要滿(mǎn)足可持續(xù)性建筑的要求。

新增的樓層決定采用預(yù)制木鑲板的輕質(zhì)結(jié)構(gòu)，其優(yōu)勢(shì)在于相對(duì)緊湊的施工進(jìn)度，將給原單元居民帶來(lái)的噪音和干擾降至最低程度。

新的木樓層所有的墻板和天花板構(gòu)件都是工廠預(yù)制的（包括礦棉保溫材料），并在現(xiàn)場(chǎng)裝配。

立面翻新的目標(biāo)是對(duì)原建筑進(jìn)行更新，以便長(zhǎng)期出租，并傳承德國(guó)北部的建筑文化：原立面上增加了外保溫，并包新磚面——與過(guò)去的丹麥薄板規(guī)格相同，但色調(diào)不同。斑駁的光影讓燒結(jié)磚展現(xiàn)出粘土材料的天然魅力。

原住宅樓陽(yáng)臺(tái)外貼人造黃色燒結(jié)磚和青綠面磚；現(xiàn)在改為手工模制磚，體現(xiàn)出古樸的質(zhì)感。

上幾層的立面以能形成天然變化的粗糙雪松片瓦做為立面材料。這樣，新建筑的輕質(zhì)特征就會(huì)一目了然；新的樓層從下方碩大的原有建筑上凸起，并呼應(yīng)著周?chē)鷺?shù)木的材質(zhì)（故稱(chēng)樹(shù)屋）。

新增的47個(gè)單元大多為復(fù)式。遵照樹(shù)屋的概念，所有的公寓都設(shè)有寬敞的屋頂平臺(tái)，而且復(fù)式公寓還有敞廊。

從配置和尺寸看，新公寓的平面設(shè)計(jì)特別考慮了家庭因素，而這是為了吸引未來(lái)的年輕租戶(hù)。

總的來(lái)看，設(shè)計(jì)策略追求的目標(biāo)是讓住宅樓的總可用面積加倍，同時(shí)讓碳排放減半?！酰ㄉ袝x 譯）

The task was to densify a residential district dating from the 1950s – which is attractively located at the edge of the city – in a contemporary way and to rehabilitate the existing housing stock without masking its origins or historic character, at the same time updating the energy infrastructure.

Opted for in order to retain the open character of the settlement was the addition of upper stories,a new development which heightened the existing structures. The design parametres for the project entailed updating the energy infrastructure in a way consistent with the settlement's existing constructive and architectonic character, while at the same time satisfying requirements for sustainable building in the additional stories.

The decision for the addition of new upper stories by means of lightweight construction in prefabricated timber paneling also featured the advantage of a relatively com-pressed construction schedule, and hence minimal noise and disturbance for residents of the existing units.

All of the wall panels and ceiling elements of the new wooden stories were prefabricated at the factory (including mineral wool insulation) and assembled on location.

The objective of the fa?ade renovation was to upgrade the existing structures for the sake of longterm rental possibilities, and to support the building culture of northern Germany: the existing fa?ades were given an external layer of insulation and clad in a new layer of exposed brickwork – a Danish thin format as before, albeit now in a different tone. In its variegated shadowing, the clinker brick brings out the natural character of the clay material.

The original estate, with its seemingly artificial yellow clinker and turquoise tiling as balcony cladding, was replaced by hand-molded brickwork featuring a rather archaic materiality.

The building material for the fa?ades of the upper stories was wood, in the form of rough,split cedar shingles whose finish features qualities of natural variation. In this way, the lightweight character of the new construction is visible externally; the new stories are set off distinctly from the massive existing structures below, at the same time echoing the surrounding stands of trees in their materiality (treehouses).

The majority of the altogether 47 new units are configured as maisonette types. In keeping with the treehouse concept, all of the apartments enjoy spacious roof terraces, and the maisonette apartments have loggias as well.

In terms of configuration and dimensions, the plans of the new apartments are designed to be especially family-friendly, a measure designed to attract younger tenants in the future.

In general, the planning measures pursued the objective of doubling the estate's overall usable area while at the same time halving CO2emissions.□
