The Westerwal project in Oudewater is the result of the transformation of a small-scale industrial site into a residential neighbourhood, based on an urban design masterplan by West 8. Within this plan, Monadnock designed six small-scale projects, each occupying a location that called for a distinctive architectural response in the new district. These include four single-family houses, an apartment building, and a parking garage. Together, they anchor the site's industrial heritage within the new neighbourhood.

At the heart of the plan stands de Pleinwachter, containing seven starter apartments. The building can be read in two different ways. A subtle bend and variation in height suggest that it consists of two separate volumes, creating a distinctive silhouette, while the central entrance and the consistent material palette unify both parts into a coherent whole. Bright and optimistic in character, de Pleinwachter contrasts with the adjacent dark parking garage. The façades are finished in stucco, with subtle ornaments above the windows that reference traditional façade decorations. Green window frames and roof edges add refined depth and establish a visual connection with the parking garage.

In contrast to de Pleinwachter, the black parking garage has a restrained appearance and a familiar, archetypal form. Its large asymmetrical hipped roof gives the building a low profile that responds to the scale of the surrounding neighbourhood. The entrance to the garage is marked by the distinctive termination of the roof ridge. On both long sides, storage units for the surrounding homes are integrated into the building and are clearly distinguished from the main volume by their stepped composition.
