Exhibition ‘City in Densification’ – City Hall The Hague. Our design for the roof structure at Stuyvesantstraat 290 in The Hague was exhibited at the exhibition ‘City in densification’ from the annual report of the Welstands and Monuments Commission 2021-2022 in the city hall in The Hague.
the annual report of the Welstands and Monuments Committee 2021-2022
Every year, the Buildings and Monuments Committee, in collaboration with the Monuments Care and Buildings Department, presents its activities in an annual report. It also explains who sits on the committee, how they work and which plans have been reviewed. This annual report focuses on the ‘City in Density’, the results of which can be seen from 23 June to 28 August in the poster wall of the Hague Municipal Archives in the Atrium The Hague.

In roof design and construction the design principles have a balanced and coherent streetscape while also integrating sustainable construction methods. Various sustainable methods have been brought to life in the roof structure for Stuyvesantstraat 290.The roof structure also fits naturally within its context as the design follows the symmetrical street profile and a coherent streetscape with solar roof tiles shaped in a traditional way as for the the rear it is a green roof system.
At the back there is a clearly elaborated concept of frame that is cladded in zinc. The planters, the fencing and the frame are generic elements of the roof structure connecting to the surrounding context. The roof has multiple functions but one of the focus points is the rear portion as it is designed as a ‘conservatory’, where the residual heat from the greenhouse is used to heat the roof structure and the house below in a sustainable manner. The sustainable construction methods in combination with the use of a green roof and solar panels ensure a roof structure enhance the living environment within and surrounding.

Spatial foundation
Last year, Global Architects, in collaboration with Rike Speelman of Natural Less and TU Delft, researched a new sustainable heating concept. Passive heating in the “conservatory” plays an essential role in this. This concept is grounded in construction engineering by Gwynn van Broekhoven with her graduation research at The Hague University of Applied Sciences. As a pilot for this research, Global Architects, in collaboration with Rike Speelman, designed a roof structure on top of its existing 1930s apartment on Stuyvestantsestraat in the Bezuidenhout district of The Hague.
Construction method: The roof structure will be built from recycled wood, dried grass as insulation material and meet all modern requirements.
Rike Speelman says the following: We are looking for ways to apply sustainability in existing buildings. Modern without losing sight of old style elements. In short, appropriate innovation. Appropriate for the preservation and aesthetic to the architectural style.

The conservatory of the roof structure is integrated in such a way that it is fully equipped with HR++ insulated folding front and this is the actual rear facade of the roof structure. Due to the large glass surface in the rear facade and the last part of the roof surface, this space will quickly be heated by the sun. By placing an internal wall with sliding doors, we can realize the desired energy concept.
The facade of the roof structure must match the existing architecture and previously roof structures in the street.
It was decided to raise the planter and to execute it in the ‘same’ facing brick as the existing architecture. The planters ensure that the 1930s architecture is continued in the new layer of the roof structure. The green character that the planters bring with them underlines the sustainable character of the roof structure and forms a natural transition to the roof structure.
Subsequently, a zinc frame was designed, with a gap of 350 mm to the closed facade panel, making the frame clearly legible. A decentralized heat recovery system is placed in a closed facade panel, so that the roof structure is ventilated in a sustainable way. The planters, the fencing and the frame are the generic elements that touch back. The infill within the frame can change within the proposed measurement system. As a result, future neighbors, who also want a construction, have the option of moving the closed panel so that it can connect to an inner wall, if they want 2 bedrooms at the rear.
The future neighbors, who also want a structure, can choose the distance from the frame to the planter themselves and therefore have an influence on the size of the roof structure and the outdoor space. The zoning plan provides for a complete development of the building area. In the case of the client, we choose this option. The last part of the roof structure will be designed as a conservatory, where the residual heat from the conservatory will be used to heat the roof structure and the house below in a sustainable manner.
Research into sustainable roof construction in The Hague
The environmental permit was granted in 2022. The roof construction will be realized in 2023. The roof structure will become a pilot house for an innovative sustainable way of building.
The following sustainability principles will be reflected in the roof structure:
– conservatory for sustainable heating and ventilation of the house
– the shell is made of recycled wood
– environmentally friendly insulation material made of dried grass
– sustainable green roof
– electricity generation by PV panels in the form of roof tiles
– hot water through a solar boiler
– LED-lighting
