Knowles London Basements


Knowles will help you discover a space you never knew existed, creating single or double depth basements to provide extra space for a multitude of uses – from living spaces to leisure areas such as swimming pools and gyms. With value engineering at our core, all Knowles projects are designed to be cost effective and time efficient.

Alongside basements, Knowles are regularly instructed to execute complete residential works, keeping the redevelopment entirely under one roof.

Site Investigation & Preparation | Demolition | Scaffolding | Most forms of Piling | Propping | Shoring | Jacking | Groundwater Control | Façade Retention | RC Concrete Form Works | Slabs | Walls | Excavation and Disposal of Excavated Material | Most forms of Waterproofing

Knowles can go a step further and take your project to a ‘white box’ phase.
