Case study
Mansion of Count Juozapas Tiskevicius
The building at Zygimantu str. 3 is located in the historic Radvila dynasty jurisdiction along the Neris River. Designed in 1859, it became the first representative building on the newly formed riverside embankment. In 1891, the property was reconstructed by Count Jonas Juozapas Tiskevicius, including the addition of an orangery that gave the building its distinctive character.
Nationalised in 1940, the building later served as a Red Cross hospital and played an important role during the tragic events of 13 January 1991.
For this project, BOISROIS designed and manufactured historical-style timber windows, preserving the building’s architectural authenticity while meeting modern performance requirements for acoustic and thermal efficiency, airtightness, and durability.
Great George St
We supplied timber windows for one of Leeds’ most exclusive refurbishment projects. In total, we produced 341 sash windows.
As the building is located on one of Leeds’ main streets, the project required exceptionally high acoustic performance.
One of the key challenges was manufacturing extra-large sash windows – some reaching 3 meters in height and weighing over 300 kg. Despite the complexity, our team successfully delivered every unit with the required precision and performance.
Burnsall Street
Nestled just off the iconic King’s Road in Chelsea, Burnsall Street is a charming and picturesque residential enclave celebrated for its quiet elegance and historical resonance. The architecture along Burnsall Street reflects mid 20th century sensibilities orderly façades, classic casement windows, and thoughtful access to light and outlook.
Our project involved a sympathetic yet transformative upgrade: the installation of heritage style double glazed casement windows, along with matching French doors and entrance doors. The goal? To modernize thermal performance and usability, while preserving the street’s elegant rhythm and historic context.
JERWOOD SPACE
At the end of year 2024, we completed the bespoke production of new windows and doors for Jerwood Space on Union Street, London — and now the site is fully finished.
This was a great project to be part of. The brief called for tailored solutions that respected the building’s character while upgrading performance. We’re proud to have contributed to a space that plays such a vital role in the UK’s creative community.
The Mansion
In 2018, Boisrois had the privilege of producing custom windows and doors for a grand Grade II listed mansion in Sandbach, converted into 17 luxury apartments. The project required windows that would maintain the mansion’s historic charm while offering the comfort and efficiency expected in modern living spaces.
For this elegant property, we crafted 96 sliding sash windows to echo the original design, preserving the architectural character that defines this remarkable building. Additionally, we produced 12 bespoke entrance and French doors, each tailored to complement the mansion’s stately aesthetic.
Using advanced glazing techniques, we were able to achieve excellent thermal efficiency and sound insulation, combining classic appeal with modern performance. This project highlights Boisrois’s dedication to blending traditional style with cutting-edge window solutions, adding value to cherished heritage properties.

BOISROIS is proud to produce windows and doors for this historic building.

To meet these needs, our team is using vacuum glazing, which offers excellent sound and thermal performance.

Boisrois was entrusted with the task of crafting Georgian-style windows and doors to complement the architectural style of the development.

The client was keen to keep the windows and doors classy and elegant, and opted for Joa’s White colour for the exterior and Worsted, Cornforth White, Skimming Stone for the interior depending on the floor.
Due to the nature of the project, owners could not be expected to put up with unwanted noise and the windows were specified to meet the specific noise reduction.
Period style entrance doors were made from hardwood and finished in Mahogany 36 Full Gloss on the outside, and Worsted Estate Eggshell on the inside, to match the interiors.
Cotswolds House
BOISROIS produced windows along with lift&slide doors from Larch for this wonderful house in the town of Costwolds.

When opened, it creates a 3.5 meter entrance. The client also required the door to seal firmly and tightly to prevent the winds getting through. Since the house is located in rural area, the doors were produced with enhanced security features so the house owner doesn’t have to worry about the houses safety.
