Loft Conversions

Loft conversion are an ideal way to add space and value to your home. We take great care to avoid disruption or disturb residents whilst the work is being completed, ensuring precautions are taken to avoid damages to the current property structure, walls, flooring and furniture.


As part of our service, you will benefit from our contractors which include architectural and structural engineers.


If you are in the early stages of your loft conversion project, we can help you with all the required planning application and additionally, guide you on site surveys and the general project management.


We aim to keep everything from consultation to a finished loft conversion in house to guarantee an easy transition from start to finish and ensure your satisfaction.




One of the most effective ways to create space in your property is by building a basement under your property. At DNL Klos we have a wealth of experience constructing basements by working with leading architects and engineers.


Our basements have been used to add swimming pools, wet rooms, cinema rooms, living area space and even sleeping accommodation.


We also offer basement remodelling, which typically is a requirement we receive when the project initially was not built correctly and issues such as cracks in foundation walls are visible, large trees or shrubs are too close to the foundation, location and condition of water heaters and air conditioning create condensation lines, and mouldy smell even though the basement appears.


We believe, it is important to create the proper environment in order to avoid moisture, dampness, or standing water into your basement, so we will take care of this aspect and create a structurally safe area for you and your family to fully enjoy.
