The Sonnenhof site is centrally located between Bahnhofstrasse and Schaffhauserstrasse and covers a good 20,000 square metres. Today, the site is dominated by a shopping centre from the 1970s, other commercial and residential buildings and a large sealed car park. It is precisely this structure that is now to be fundamentally changed.
The plan is to create a new, mixed-use district with a public passageway, green courtyards and squares, businesses, restaurants and a cultural and meeting centre. The existing shopping centre will not disappear, but will be modernised and integrated into the new structure.
Urban densification
At the heart of the project are around 240 rental flats in various price categories and with different floor plans. In addition, there are around 12,000 square metres for commercial, cultural and public uses on the ground floors and in the passages.
In terms of urban planning, the project focuses on density and orientation. Four taller buildings will mark the site and give it a clearly recognisable address. The design plan allows for a maximum building height of 55 metres on the north-eastern corner. This shows how clearly the Sonnenhof will stand out from the previous scale.
Open space instead of tarmac
The message is particularly strong in the outdoor space. Where heat-retaining pavement dominates today, unsealed surfaces, trees, courtyards and climate-resistant planting will improve the microclimate in future. Rainwater will be able to seep away and evaporate, roofs will be greened and supplemented with photovoltaics.
The project also aims to reorganise traffic flows. Most of the above-ground parking spaces will be moved to the underground car park, while paths and squares will be designed primarily for pedestrians and cyclists. Nevertheless, around 450 car parking spaces will remain on the entire site.
Culture as part of the development
The combination of property development and public use is striking. The planned KUBEZ cultural and meeting centre at Sonnenhof will not only be built, but will also create a regional meeting place for culture, education and leisure. The project is being developed in collaboration with the town of Bülach and neighbouring municipalities.
This is what makes the Sonnenhof more than just a classic development. The site should not only provide living space, but also create a new centre that expands the everyday life of the town and strengthens the connection between the railway station, town centre and neighbourhood.
A long road to the new centre
Sonnenhof is still a planning project. the private design plan is due to be submitted in 2026, with approval scheduled for 2027. The first stage could start in 2029 and be completed in 2031, with overall completion scheduled for 2034 according to the project status.
This shows the true scale of such projects. The transformation of a central site requires not only capital and design power, but above all time, procedures and political coordination. If Sonnenhof succeeds, Bülach will not simply gain new flats. The town will gain a new piece of urbanity.
