代尔夫特水务局位于Oude Delft的Gemeenlandshuis历史建筑内。这座纪念性建筑建于1505年，最初作为Jan de Huyter的住宅使用。该建筑的砂岩立面在当时是独一无二的设计，同时它也是为数不多的在1536年的城市火灾中幸存下来的建筑之一。而现在，这座建筑由Delfland水务局接管使用。

The Delfland Water Authority is located in a historical building on the Oude Delft: the Gemeenlandshuis. The monumental part was built in 1505 as a house for Jan de Huyter. The sandstone facade was unique for that time and it was one of the few buildings to survive the 1536 city fire. More than 100 years later, the house came into the hands of the Delfland Water Authority.

新的房屋|A new housing
Over time the Water Authority expanded to include several adjacent monumental buildings, and in 1975 a new building on the Phoenixstraat was added. In 2014, the Water Authority decided to revise its housing strategy. The most important task was to make what was once a fragmentary complex into a cohesive whole. The ambition was to transform it into a pleasant, flexible working environment that reflects both the requirements of modern time and the identity of the Water Authority, while maintaining the special characteristics of the monumental elements.

Mecanoo团队选择了 “View of Delft” 作为此次设计的主题。首先，设计师对所有的建筑都进行了分析，分清它们的优缺点所在，由此形成设计策略，一条新的通道被建造在场地上。这条通道连通内部特定的位置，并穿透整个建筑，同时将内外空间相互连接。在该通道中，人们可以看到造型独特的炮塔、历史悠久的周边建筑、老教堂和庭院。这一设计也帮助游客辨明自己的位置。其中一部分被打造为“荣誉画廊”，用于展示水务局在建立的百年间收到的各式礼物。
Mecanoo chose the theme ‘View of Delft’ as the starting point for the design. First, all parts of the building were analyzed: what are the striking qualities and what are the defects? By making openings at strategic locations, a clear route has been created. The route links special interior objects and see-throughs in the building, but also connects the inside and the outside with views to the characteristic turret, the surrounding monumental buildings, the Old Church, and the courtyard. This helps visitors to orient themselves. Along part of the route, an exhibition was arranged in the form of an ‘honorary gallery’ with objects and gifts received by the Water Authority during the hundreds of years of its existence.

The historic rooms have been restored and the technical installations have been (unnoticeably) renewed. Where building parts adjoin each other, a clear node has been created. Elements from different periods create beautiful contrasts. This is clearly visible at the new glass entrance where a glass front has been placed in front of the original facade, creating a covered patio. The windows in the old facade have been replaced by open wooden frames. An oak walkway crosses the entrance area and forms the connection between two building parts. The striking round reception desk features the Delfland Water Authority logo.

The graphics on the glass walls of the conference center were designed by Silo and inspired by the enormous wealth of antique water maps belonging to the Water Authority. In cooperation with the Textielmuseum Tilburg, Silo also designed a tapestry, made of millions of water droplets. It is the eye-catcher of the central hall.

The parking lot at Phoenixstraat has been transformed into an attractive square that leads to the entrance. The existing yellow pavers are laid in the original pattern, from which the round wind rose emerges beautifully. Behind the square is a meeting garden where something is to be experienced during all seasons. The garden also serves as a water buffer. Vegetation is planted in a playful geometric pattern, intersected by walking paths. Here and there, private squares have been created where one can sit in the green. Where once was a busy loading and unloading area, now lays a welcoming oasis of peace.
