这是由NOMADE Architects设计的班多尔赛马场。这个修复和扩建项目位于法国伊菲尼阿克，距市中心Saint-Brieuc约几公里。建筑师营造了一种独特的场地环境，对建筑加以改造，建立了新旧建筑之间的动态联系。整体设置中整合了一个大胆的形态类型，这是一个双重挑战，一方面旨在改善马术比赛活动的公共接待能力，另一方面提供集体活动的功能空间，如讲座、婚礼等。

该项目由两部分组成，现状的赛马场是一个配有看台的有屋顶的大厅，它包括四个区域：公公接待厅、专业接待厅、更衣室和公共酒吧。这部分主要以翻新为主，使其满足PAB标准（消防安全、PRM通道）以及改善技术、声学和热性能（隔热、外部细木工改造）。这些升级将大大改善用户的使用舒适度。而新建部分将提供新的空间和功能：餐厅、专业会议室及相关配套。它是由几个脚柱上的模块，悬挂在现状大厅的西北立面，以及西南里面的不透明体块。这种建筑解决方案减少了占地，并避免了影响整个赛马场的运营。
From the architect. NOMADE architects recently delivered the project for rehabilitation and extension of the “Hippodrome de la Baie racecourse in Yffiniac”, a few kilometres from the downtown Saint-Brieuc, in Brittany. NOMADE architects developed a unique context-sensitive yet singular design to renovate this structure, establishing a dynamic dialogue between the old and the new.An audacious morphology integrated in its setting. This is a two-fold challenge, intended on one hand to improve public reception conditions during equestrian events, and on the other, to provide a function room for group events (seminars, weddings, etc.).

The project is organized in two parts; The existing racecourse is a covered hall with bleachers. It has four areas: the public reception hall, the professional reception hall, the changing rooms and the public bar.This building was refurbished to bring it up to PAB standards (fire safety, PRM access) and to improve technical, acoustic and thermal performance (insulation, renovation of external joinery). These upgrades significantly contributed to improved user comfort.The extension will offer new spaces and uses: a restaurant, a professional meeting room and the service associated with the main areas that distribute the space.

It consists of several modules on stilts, hung from the northwest fa?ade of the existing hall, together with an opaque block in the southwest side. This architectural solution minimizes the footprint and avoids affecting overall racecourse operation.NOMADE has made an audacious choice to embody this reinvented identity, making use of its considerable expertise in bio-climatic design: orientation, compactness and sun protection.

Alternating between continuity with and divergence from the existing design, the modules on stilts play with this duality: opacity and transparency, shadows and light, sky and land. Far from being futile, this play makes it possible to manage sunlight and internal heat, ensuring summer and winter comfort. A naturalistic pattern increases the architectural expressiveness, stimulating the imagination and playing with the concept of a double skin.

The covered hall with a 43m x 64m rectangular floor plan is organized into two distinct entities: the space reserved for jockeys, combining a hall and the changing rooms located under the bleachers, and the public reception area.The public reception hall is a generously-proportioned space, open and friendly.A system of mezzanines, walkways and open landings enhances this vast volume, promoting clear views that make its distribution easy to understand. This makes the hall the perfect place for gathering, meeting and providing directions. It also offers a wide variety of uses.

The extension offers new spaces and uses on the ground floor. Its design is modular: three metal frame modules, two of which stand on concrete-filled metal posts, hang from the glass north wall of the covered hall.A concrete monolith connects it to the glass gable end of the existing buildings. This connection houses the circulation between the racecourse’s two entities and distributes the various spaces and programmes, as well as housing the technical premises.This monolith is designed as an opaque volume, pierced by random windows. Rough concrete is used outside, contrasting with the coloured concrete inside, creating a friendly atmosphere. Its rough appearance serves as a harmonious foil to the main hall.

In terms of structure, NOMADE sought to design an extension that respects the structure and operation of the existing covered hall. The project limits its overall impact and establishes a true architectural interaction with the existing building through a steadfastly unique stance.The new building will connect to the existing one by the glass gable of the northwest fa?ade. The extension chooses to mark a strong contrast with the existing structure through its design and materials, yet respects the longitudinal layout naturally imposed by the racetrack.

The combined use of metal and concrete offers considerable latitude to architectural creation. This is why the modules have a metal or mixed structure mounted on concrete-filled metal posts.The supporting structure on the fa?ade is mainly made up of steel beams carrying composite floor slabs (concrete slab in metallic formworks).

The facade consists on a filter that alternates clear and opaque surfaces, creating several sequences. This filter consists of aluminium cladding placed against the primary structure of the building. It covers the fa?ades with a greater or lesser density, according to the need to open up or obscure the view or provide protection from the sun.The stairwells and lifts have a concrete structure (load-bearing walls) and brace the entire extension building. An expansion joint has been created between the existing building and the extension.The accessible terrace overlooking the show ring consists of a concrete slab. The roof is a waterproofed and insulated concrete slab finished with a vegetated roof.
