One partner for everything that has to be visible in your project
Anyone running projects or managing several sites rarely needs one supplier — they need eight. With us, façades, signage, wayfinding, bicycle parking, street furniture, interiors and events all come from one party. We define the concept, design it, produce it in-house, install it with our own teams and stay available once it is up. You keep one point of contact and one party responsible.
No obligation. We get back to you within two working days.
For anyone who has to have more than one thing made at once
Whether you build, design, manage public space, have several sites in your care or put on events: as soon as a number of visible elements have to add up, fragmentation becomes your problem. These are the four situations we see most often. Don't recognise yourself in them but work on a project basis? Request the partnership anyway — we look at each organisation on its own terms.
You build or renovate
Contractors, developers and clients of works
You hand over the building, we supply everything visible on and around it. Façade cladding, signage, wayfinding, bicycle shelters and site furnishing all come from one party, with one schedule and one site contact. No five subcontractors pointing at each other as handover approaches.
You design and specify
Architects, engineering firms, interior architects and design studios
You design, we make it buildable. Our experts think along about material, fixing and maintainability, supply the technical drawings and visualisations for your file, and then produce what was drawn. Your design intent survives all the way to the site.
You manage public space
Cities, municipalities, inter-municipal bodies and public institutions
One supplier for street furniture, bicycle parking, signage, election equipment and event dressing. We follow tender specifications, supply the technical sheets and certificates your file needs, and remain reachable for maintenance and replacement parts — even years after installation.
You manage multiple sites
Facility managers, property managers, retail chains and multi-site brands
What stands at one site has to match the next. We keep your brand consistent across every location, deliver in phases and keep track of what was installed where. A replacement or a new site therefore does not become a new project, but a reorder.
What taking work off your hands actually means
One point of contact for the whole package
One project lead for concept definition, design, production, installation and aftercare. You call one number, also when something changes halfway.
Concept definition up front
Our experts, each with more than fifteen years of experience in their own field, jointly determine what works best for your project. Only then is anything drawn.
Our own production in Olen
What we design, we largely make ourselves. That removes links in the chain, and above all it saves time when something changes halfway.
Our own installation teams
Including at height and in public space. We do not just deliver.
Technical support inside your file
Drawings, visualisations, material sheets and certificates for permit applications and tender specifications.
Maintenance and replacement
Cleaning, repair and replacement of parts, also across multiple sites and years after handover.
Access to the Herva-Doublet Platform
As a partner you get your own login to our facility platform. It holds the full range with your partner terms, lets you build and track quotes, and shows you what has previously been supplied for your projects. Reordering for a second site or a next phase therefore takes minutes instead of e-mails.
Prices never appear on the public site. They are visible only behind your login, once your request has been approved.

Frequently asked questions
What does a partnership cost?
We discuss that at the introduction, matched to the kind of projects you run. The request itself is free and without obligation.
Do we have to meet a minimum volume?
We look at what makes sense per organisation. Even a few projects a year is enough to join.
Do you work as a subcontractor on our site?
Yes, we do that regularly, with our own installation teams. Arrangements on scheduling and site safety are agreed beforehand.
We already have a fixed supplier for one item.
Not a problem. Many partners start with a single family — signage or bicycle parking, for instance — and expand once it works out.
What about public tenders?
We follow tender specifications and supply the technical sheets, certificates and references a file needs. For local authorities that is often where the collaboration starts.
How soon do we get access to the platform?
After the introduction and the approval of your request, in practice within a few working days.
