Dutch ornamental-plant grower Pligt Professionals is developing a new high-roof greenhouse in ‘s-Gravenzande, in the Westland growing region, to expand and reorganise production of 14-centimetre potted roses. A 22 September 2026 FloralDaily interview describes a 12-metre-high building concept intended to accommodate more automation and vertical use of space. The project is under construction, not an operating facility delivering measured gains.
Greenhouse contractor VB identifies the current Pligt project on Naaldwijkseweg as approximately 3.3 hectares, consisting of a lower section of about 1.5 hectares and a higher section exceeding 1.7 hectares. VB says the lower area is under construction, with the taller section to follow, and indicates an expected end-2026 completion. The builder specifies column heights of 6 and 9.8 metres respectively; these are structural measurements, not necessarily the same as the 12-metre overall building height described in the interview.
Design targets potted-rose handling and automation
Pligt’s commercial representative Gerard van den Assem told FloralDaily that the height and layout are intended to make room for more efficient logistics, plant handling and vertical use of the greenhouse. The grower is considering further automation of labelling, cutting placement and packaging. Insect screening is planned for the vents, supporting the company’s goal of reducing pest pressure and dependence on crop protection products.
Energy plans described in the interview include geothermal heat, readiness for electric heat pumps and dimmable LED lighting. Pligt aims to reduce fossil-energy use through these measures, but the proposed savings should not be presented as already measured results of the new greenhouse.
Why the project matters to greenhouse suppliers
The development links commercial floriculture growth to equipment choices involving structure height, internal handling, climate control, lighting and pest exclusion. The combination of two structural sections also indicates that production and logistics functions may be planned together, rather than adding conventional growing area alone.
For suppliers and investors, the relevant next milestones are the remaining construction stages, actual equipment deliveries and commissioning. Pligt’s earlier greenhouse expansions are separate projects and should not be conflated with this 2026 site.
What remains undisclosed
The total investment, final technology vendors, production capacity in plants per year and measured operational savings have not been confirmed in the sources. VB’s expected completion timing is a project forecast, not proof of handover.
Key takeaways
- Pligt Professionals is building a new approximately 3.3-hectare potted-rose greenhouse in Westland.
- Project plans include contrasting structural heights, automation, insect screening and new energy systems.
- End-2026 completion is the builder’s expectation; cost, equipment contracts and actual performance are not yet verified.
