As a vast natural area, the centuries-old Sonian Forest is unique in Belgium's heritage. With its robust trees, the forest is known as an ecological zone with a diverse range of recreational possibilities. The Sonian Forest is spread over three regions, which gave rise to very fragmented communication.

The assignment included research into the possibilities of harmonising the identity of the forest and the development of a logo with a house style with which the Sonian Forest can profile itself. In addition, we investigated which graphic and typographic requirements are necessary to achieve a quality image of the Sonian Forest and develop the complete signage. The established graphic and typographic identity will be translated into various communicative carriers.

Custom designed wordmarque

We built the Sonian Forest’s corporate identity around an sober wordmarque. We designed new letters for the logo. In the design, we tried to portray the atmosphere and character of the Sonian Forest: a natural mix between old and new, between history and future.

The Sonian Forest stretches over the Flemish, Brussels and Walloon region. We brought  the visualization of the three regions together by using the Greek ‘E’. A striking and yet discreet reference to the three governments that manage the forest.  The addition of this symbol created full but sober wordmarque Zoniënwoud/Forêt de Soignes.

The typeface

In this house style, the Sonian Forest has not only been given a unique and recognisable logo, but also a specially developed typeface. The ‘characters’ are an important element in the recognisability of the house style. The ‘SonGrotesque’ typeface conveys the atmosphere of the wordmark in all possible communication applications. The name of the typeface has its origins in the oldest name of the Sonian Forest: ‘Sonia’. The appearance of the letters refers to the slender, grand shapes often found in the Sonian Forest.
