DS5 Construction

About Us

Who we are

DS5 Construction Ltd is a family-run construction company based in London. We deliver residential and commercial projects, including renovations, extensions, refurbishments and new builds.

Founded by Ivan Shushvar, the company is built on hands-on construction experience and a practical understanding of how projects are delivered on site. That background continues to shape the way we work today, with a strong focus on clear communication, careful organisation, attention to detail and reliability at every stage.

Our services include house renovations, house extensions, summer houses, structural works, full property refurbishments and new builds. We oversee projects from start to finish, working closely with architects, engineers, and other consultants to maintain clear coordination and on-time delivery.

Our team brings together practical experience, technical knowledge and a strong understanding of current materials, methods and regulations. We take a considered approach to each project, focusing on solutions that are appropriate to the property, the brief and the long-term performance of the finished space.

At DC5 Construction Ltd, we place strong emphasis on qualification, compliance and professional standards. We work with fully trained and qualified specialists, and we provide all relevant certification where required, including certification for electrical works, gas works and boiler installations. This helps ensure that key systems are installed correctly, safely and in line with current UK requirements.

All works are backed by a workmanship guarantee, providing additional assurance of quality, reliability and long-term performance.

Our aim is to deliver spaces that are well-built, well-finished, and designed to last, while providing a smooth, well-managed experience from concept to completion.

Our Projects

Great Portland

Office Building RedevelopmentOne 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 The project began with strip-out and demolition works, including the removal of outdated partitions and sanitary installations that no longer met current requirements.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.
