位于挪威Brumunddal的Voll Arkitekter公司的Mjøstårnet大楼已被高层建筑委会和城市人居环境委员会证实为世界上最高的木构建筑。

这座高85.4米的高层建筑是用交叉型复合木材（CLT）建造的，这是一种可持续使用的新型材料。

继Vancouver的53米高的Brock Commons Tallwood House后，该建筑被命名为世界上最高的木构建筑，它是一个木材和混凝土的混合结构。位于挪威Bergen的Treet有49米高，在2019年3月Mjøstårnet完工前曾是最高的全木建筑。

Mjøstårnet by Voll Arkitekter in Brumunddal, Norway, has been verified as the world's tallest timber building by the Council on Tall Buildings and Urban Habitat.
The 85.4-metre-high tower was built using cross-laminated timber (CLT), a pioneering material that allows architects to build tall buildings from sustainable wood.
It has taken the title of world's tallest timber building from the 53-metre-high Brock Commons Tallwood House in Vancouver, which has a hybrid wood and concrete structure. Treet in Bergen, Norway, which is 49 metres high, used to be the tallest all timber building until Mjøstårnet completed in March 2019.

这座第三高的Mjøstårnet是由挪威实践公司Voll Arkitekter为AB Invest设计的。这座18层的多功能建筑涵盖了公寓、酒店、游泳池、办公和一家餐厅等功能。

木材专家 Moelven Limitre 公司是该工程的木结构承包商，他们设计了由CLT构成的电梯轴，以及由Glulam制成的立柱。Glulam是用木头制成的，将它们黏在一起作为建筑内部的梁柱结构，用来代替混凝土或钢构件。

Mjøstårnet, the third-tallest building in the country, was designed by Norwegian practice Voll Arkitekter for AB Invest. The 18-storey mixed-use building contains apartments, the Wood Hotel, swimming pool, office space, and a restaurant
Timber specialist Moelven Limitre installed the building's timber structure, including elevator shafts made entirely from CLT, and columns made from glued laminated timber (glulam). Glulam is made from wood that is planed then glued together to form columns or beams, and can be used in the place of concrete or steel elements.

Mjøstårnet在五个施工阶段中每阶段修建四层。施工时利用一个内部脚手架和一个大型起重机来吊起工厂内预制的结构，在相应的位置进行组装。

由于Brumunddal是挪威的一个主要林业和木材加工业地区，因此建筑所用的材料都是在当地的特色材料。

CLT和Glulam材料吸收了空气中较多的碳元素，因此它们的强度足以承受较大的荷载。

针对高层木构建筑数量不断增多的情况，高层建筑委会和城市人居环境委员会最近修订了他们关于木构建筑的准则。

Mjøstårnet was built four storeys at a time in five construction stages. An internal scaffolding and a large crane was used to hoist the pre-fabricated sections and floor slabs into place.
As Brumunddal is an area of Norway with a major forestry and wood processing industry the materials were sourced locally.
CLT and glulam are strong enough to support large loads, and using timber means the carbon absorbed from the atmosphere by the trees is locked into the structure permanently.
The Council on Tall Buildings and Urban Habitat (CTBUH) recently revised its guidelines to recognise timber as structural material in response to what it described as an "uptick" in the number of tall timber buildings around the world.

随着城市内的建筑密度越来越大，全球范围内的高层建筑数量在持续的增加。CLT作为一种新的可持续材料正在成为越来越多建筑师的首选。

Penda设计了一个高层住宅和垂直结构农场的概念性方案，Anders Berensson建筑事务所为斯德哥尔摩设计了一个由31座木制摩天大楼组成的城市概念方案。

在英国，建筑师们呼吁政府废除CLT不可做耐燃材料的禁令。因为这种材料不仅比钢材更环保，而且具有耐燃的性能，同时在燃烧时不会释放有毒的气体。

As urban areas grow denser than ever and the number of tall buildings being built globally continues to rise, many architects have turned to CLT and other engineered timbers as a more sustainable building material.
Penda has designed a concept for a residential tower and vertical farm hybrid, and Anders Berensson Architects has developed a proposal for a city of 31 wooden skyscrapers for Stockholm.
In the UK, architects  have called upon the government to make CLT exempt from the ban on combustable cladding materials. Not only is the material more environmentally friendly than steel, it also claims to be slow-burning and self-extinguishing without releasing toxic fumes.
