Plas Gwyn位于威尔士北部Pwllheli的一处数英亩的牧场上，是一栋建造于16世纪、被列为二级保护建筑的石砌住宅。阶梯状的山墙使其成为了在当地独一无二的建筑类型。

Plas Gwyn is a Grade II* listed 16th Century stone farmhouse located in Pwllheli, north Wales within acres of farmland including pastures for cattle. The stepped gables make the ’plas’ a distinctive building type in the region.

Plas Gwyn的所有者是该农场的第三代经营者，他委托Donald Insall Associates将这座住宅扩建为一座可租用的度假屋，借助设计来吸引更多的游客。设计的重点是尽可能地利用Plas Gwyn的位置优势，最大程度地引入斯诺登尼亚山与湖泊的壮观视野。

The owner of Plas Gwyn, a third generation farmer, commissioned Donald Insall Associates to expand the existing house into lettable holiday accommodation that would inspire and attract visitors through its design. It was important that the new extension would make most of Plas Gwyn’s rural location and maximise the spectacular views onto Snowdonia and the Llyn.

建筑团队在既有房屋的基础上打造了一座以锌板覆盖的单层体量，用于容纳开放式的餐厨空间。充满现代感的设计展现出21世纪的介入特征，紧凑的体块和低屋顶使住宅与周围的农场建筑形成了和谐的关系。通高的玻璃提供了充足的日照，同时将扩建的部分与周围景观连接起来。

Donald Insall Associates created a single storey zinc-clad extension to accommodate an open-plan kitchen and dining area. The contemporary design of the extension clearly expresses this 21st century intervention at Plas Gwyn.  Yet the compact massing and low roofline of the extension sit comfortably within the context of the farmhouse architecture.  The floor-to-ceiling height glazing provides generous daylight and connects the extension to its surrounding landscape.

除扩建之外，该项目还对既有房屋尤其是基座部分进行了修复。所幸构成住宅的主要材料并未受潮，既有的木板也仍然保持着坚固。建筑团队希望将原始的内部石墙暴露出来，同时植入耐用且与之相配的新饰面（如抛光混凝土地面）。总体上看，新的材料组合很好地适应了既有的住宅原型。

Plas Gwyn required repairs including attention to its foundations but, fortunately, its fabric had not suffered from damp and its timbers were by in large sound.  Together with their client, Donald Insall Associates wanted to make the most of original stone walls by exposing these inside the house and by opting for robust and paired down new finishes in the interior, like polished concrete floors. Overall, the palette of new materials is very much in keeping with the farmhouse typology.

Plas Gwyn包含3间卧室，可以通过Airbnb预定。住宅旁边的牛棚安装了太阳能电池板，有助于提高小屋的环境效率。同时，为了保证房间的舒适度，业主还为小屋增设了采用燃油加热的地暖系统。

Plas Gwyn has three bedrooms and is available via Airbnb. Solar panels were installed in nearby cattle sheds to make Plas Gwyn environmentally efficient; but to ensure levels of comfort in the house, the client added oil-fired underfloor heating.
