Box windows that preserve the character of the building
Box windows belong to buildings with a face of their own. For owners’ associations, owners and building managers we make them to measure, so that they follow the original architecture and still serve well today. We take care of the survey, manufacture, installation and the agreed finishing work.
- Experience with heritage conservation
- 25,000+ windows made
A traditional look that still makes sense today
With box windows, proportions, depth and divisions are what count. We make them for the specific building, not from a universal template. So our design considers the facade, how the building is used and the technical requirements the new windows must meet.
We will help you find your way around restoration funding
Replacing windows in a conservation area is often funded by a municipal district grant or a subsidy programme. Contracts of this kind are nothing new to us.
For example, we delivered the replacement of the street-facing windows of the residential building at Jaselská 31 in Prague 6 under Grant no. 100 for the restoration of a building of heritage value. (from our list of references)

What you ask us most often
Ideally before you order manufacture or start any work. The sooner we look at the project, the better we can coordinate the technical solution, the documentation and the deadlines.
Yes. We have worked with conservation authorities for a long time and know which documents they need when historic windows and doors are restored. As agreed, we can act as an intermediary or take over the communication entirely.
Approval of the application depends on the funding provider, so it cannot be guaranteed in advance. But we will help you prepare the technical documents, put the paperwork together and make sure everything is submitted correctly and on time.
Send us the address of the building, photos and a short description of the planned work. We will look at your plans and tell you what is worth looking into further.
Replacement usually takes two days. The exact duration of the replacement depends on the number and construction of the windows, access to the apartment and the extent of finishing work. We confirm the schedule before installation begins.
For an indicative price we only need the number and dimensions of the windows, the type of building, and whether it is a listed building. The better the documents we receive, the more accurately we can assess your enquiry.
We use quality solid timber and laminated sections, which guarantee a long service life and dimensional stability.
Wooden windows and doors only need regular cleaning and, from time to time, a fresh coat of finish. Detailed instructions are supplied with every contract.
The choice of hinges depends on the type of window and on the requirements of heritage conservation. We will gladly recommend a suitable solution on site.
The whole process of replacing the windows in a single apartment usually takes two days. The maximum number of box windows replaced in one day is 7. All the work is normally carried out from the interior.
