Architecture studio 3XN is developing a carbon-negative extension for Hotel GSH on the Danish island of Bornholm that will be built almost entirely from wood.

Designed by 3XN in collaboration with its sustainability-focused sister studio GXN, the new eco-friendly wing will provide 24 rooms, a conference room and rooftop spa for the hotel.

It follows the studio’s completion of Hotel GSH, which is an acronym for Hotel Green Solution House, in Rønne in 2015.

The Danish studios’ goal for the extension is for it to be carbon-negative over its lifespan, which they claim “has not been seen in a commercial building in Denmark before”.

Carbon-negative buildings, also described as climate positive, are designed to absorb more carbon than they consume during their lifetime.

To achieve this, it will be built with a cross-laminated timber structure, insulated with wood fibres and clad with wooden panels. It will also utilise passive design and renewable energy technologies, and contain furnishings made from recycled materials.



為此,它將採用交叉層壓的木結構建築,並用木纖維絕緣並用木板覆蓋。 它還將利用被動設計和可再生能源技術,並包含由可再生材料製成的家具。

“If we in Denmark want to be able to achieve our climate goals, the construction industry needs to think and act differently, and there is, therefore, a great need for lighthouse projects like this,” said Kasper Guldager Jensen, partner at 3XN.

“The idea is simple – we believe that climate positive architecture combines good design and good business,” Jensen continued.

“Hotel GSH will provide a blueprint for a climate positive future and this experience is a destination worth travelling for, which ultimately makes it a good business for our client.”

3XN的合夥人Kasper Guldager Jensen說:“如果我們丹麥希望能夠實現我們的氣候目標,那麼建築行業就必須採取不同的思維和行動,因此,非常需要這樣的燈塔項目。”


“ GSH酒店將為氣候良好的未來提供藍圖,這種經歷是值得旅行的目的地,最終使它成為我們客戶的一項好生意。”

Sequestered carbon will offset carbon emissions|固碳將抵消碳排放

According to 3XN and GXN, the sequestered carbon contained in the wood used to build the new wing is expected to offset the carbon dioxide emitted by the building over its lifespan.

Sequestered carbon refers to the amount of carbon dioxide a tree removes from the atmosphere as it grows and subsequently stores as carbon. When a tree is logged for use as timber, it will continue to store it.


固存碳是指樹木生長時從大氣中清除並隨後以碳形式存儲的二氧化碳量。 砍伐一棵樹用作木材後,它將繼續存儲它。

Once complete, the studios also intend to utilise renewable energy and passive design strategies to help reduce its carbon footprint further.

According to GXN, this will include harvesting solar energy to heat water, connecting to a local energy grid that relies on renewable energy technologies and using natural ventilation to negate dependence on mechanical systems.



All building materials will be reusable|所有建築材料將可重複使用

3XN and GXN will use reversible joints throughout construction to ensure the extension and its components can be dismantled and reused at the end of its useful life.

Any offcuts from the structure will be transformed into furniture and furnishings for the wing’s interiors, ensuring there is minimal demolition waste.



In the new conference room, 3XN and GXN plan to use some debris from local granite quarries in Bornholm as decoration. This stone will also help regulate the temperature of the conference space using thermal mass.

在新的會議室中,3XN和GXN計劃使用博恩霍爾姆當地花崗岩採石場的一些碎片作為裝飾。 這塊石頭還將有助於利用熱質量來調節會議空間的溫度。

Hotel GSH also built with recyclable materials|GSH酒店也採用可回收材料建造

3XN is a Copenhagen-based studio that was founded in 1986 by Nielsen alongside Lars Frank Nielsen and Hans Peter Svendler Nielsen. Its innovation arm GXN was established in 2007.

The studios’ design of Hotel GSH in 2015 was intended to demonstrate how architecture can adopt the principles of the circular economy and utilise green building solutions. Like the proposed extension, it was built with materials that can be disassembled, recycled or are biodegradable, and utilises on-site energy production.

Elsewhere, the studios are collaborating on the 2 Finsbury Avenue office complex in central London, UK, which includes a 35-storey skyscraper.

It is being developed with the goal of being net-zero carbon in both its construction and operation through the use of low carbon materials, passive design strategies and possibly the re-use of elements from existing buildings on site.

3XN是一家位於哥本哈根的工作室,由尼爾森(Nielsen)和拉斯·弗蘭克·尼爾森(Lars Frank Nielsen)和漢斯·彼得·斯文德勒·尼爾森(Hans Peter Svendler Nielsen)於1986年成立。 它的創新部門GXN成立於2007年。

工作室在2015年設計的GSH酒店旨在展示建築如何採用循環經濟原理並利用綠色建築解決方案。 與擬議的擴展一樣,它由可拆卸,可回收或可生物降解的材料製成,並利用現場能源生產。

在其他地方,這些工作室正在英國倫敦市中心2 Finsbury Avenue的辦公大樓內進行合作,其中包括一座35層的摩天大樓。
