Once again Rose Line Premier has delivered an exceptional extension and refurbishment project to an existing home in one of London’s most picturesque neighbourhoods, Richmond. This development on Townshend Road is an example of our ability to harmoniously combine functionality with aesthetics, even when working in demanding conditions.
The building project involved a wide range of works including:
- Enlarging the existing basement and extensively renovating the interior.
- Installation of new flooring, construction of stairs and installation of a bespoke designed kitchen.
- A complete remodelling of the upper floors, including the construction of new partition walls and replacement of windows.
- Extending the plumbing and electrical systems, which ensured the entire property was modern and efficient.
- Finishing the patio and creating a new garden arrangement that enhanced the aesthetic qualities of the property.
Logistics and construction challenges.
The completion of this project required careful planning due to the close proximity of other residences. A key challenge was the logistics of the earthworks, which were carried out with the utmost care to ensure the safety of the surrounding buildings. The Rose Line Premier team successfully met this challenge, creating an open and welcoming space, ideal for family living.
Creating an open living plan.
One of the key elements of the project was a partially basement rear extension, which required major structural changes. This provided our client with a spacious, open plan living area on the lower ground floor. This new extension project allowed a seamless connection between the interior and the charming garden at the rear of the property, creating an ideal place for relaxation and family gatherings.
The end result – a harmony of aesthetics and functionality.
In 7 months, it was possible to completely transform this existing property, combining modern technology with elegance and functionality. Thanks to detailed planning, efficient project management and attention to detail, the project was completed on time, meeting all the client’s expectations.
