Usable and Practical Cellar Conversion

These conversions deal with the basic aspects of turning a damp and dingy, unpleasant and unusable space into a bone dry, and usable cellar. The emphasis is dealing with the physical threat of water rather than the look of the cellar to create an indoor room with a variety of practical uses which we can discuss and adapt together during our planning stage.

Functional and Comfortable Cellar Conversion

Your cellar will be a comfortable space that is compliant with building and fire regulations and ready for furnishing.

Every construction is unique in scope, but process is systemically applied to each construction project.

We seek to get involved early in the design phase so that we can manage the project more efficiently, provide effective building solutions, and identify challenges early on to mitigate design changes after construction commencement.

This involves detailed pre-construction planning crucial to successful construction and on-time delivery, and allows the client and team a clear pathway to the bidding process, construction phase, and through to completion.
