Great Portland

Office Building Redevelopment

One of our recent projects involved transforming a seven-storey former school building that had stood vacant for 8 years into a modern office building. DS5 Construction Ltd took full responsibility for this ambitious redevelopment, bringing the property back into use and upgrading it to meet current commercial standards.

The result is a collection of contemporary, functional office suites on all seven floors, tailored to accommodate diverse businesses.

The project began with strip-out and demolition works, including the removal of outdated partitions and sanitary installations that no longer met current requirements. We then reinstated key services, including the gas supply and electrical systems, while also developing a new internal layout designed around the client’s current and future needs.

Our construction team managed every stage of the redevelopment. This included installing new walls, floors, and ceilings, reconstructing the staircase, and installing new balustrades. We also delivered modern washroom facilities, changing areas, office rooms and a fully fitted kitchen, creating a practical and well-organised working environment throughout the building.

All works were carried out in line with the project plans, under close project management, and in accordance with current construction and design standards. The programme was carefully controlled to ensure that each stage was completed on schedule.

After 12 weeks of intensive work, the building was successfully transformed into a functional and visually coherent office environment, providing a modern setting for business activity and future growth.

Reviews

Our clients' reviews

“We discovered Ivan and DS5 through our work on a new bathroom. This was step one of a major, full apartment refurbishment. We had never done anything like this before, so we were complete newcomers to the challenges of managing a complex project of this kind. Ivan and his team impressed us so much with the work on our en-suite that it was.”

Throughout the process Ivan, Max and team provided a superb service. They gave excellent guidance and reassurance as we finalised our plans, kept us informed and the project was completed exactly.”
