The Chalk Works: Chalk-Based Renovation, Remediation and Regeneration

Project details

  • Bartlett School of Architecture Medal, MArch

Through establishing wider systems of material industrial symbiosis and methods of tailored chalk-based renovation, this project proposes the use of waste chalk ‘filter cake’ to renovate, remediate, and regenerate the derelict Shoreham Cement Works, converting it into a Chalk Works – a construction school which offers an alternative curriculum.

How can the site be brought back to life using regenerative methods that respond to its historical development? How might chalk waste be used to establish a tailored renovation method for the existing building? How might an alternative construction curriculum emerge from this material process?

In response, a chalk-based logic addresses the historic processes and conditions that exist on site while enabling new architectural, geological, and social processes to be inserted. With chalk waste driving these changes, architectural and landscape interventions take on a hybrid, homogenous quality. The research provides opportunities for broader investigations into chalk architecture, forming symbiosis between industry and construction, establishing a renovative cob construction method, and alternative material-driven teaching methods.

Chalk Waste ‘Filter Cake’ Sample: Acquired from Tideway

Chalk waste ‘filter cake’ is a civil engineering by-product composed of finely ground chalk. The material is essentially a plastic chalk, meaning the addition of straw and larger aggregates can create a useful chalk cob material.

Material Tests, Prototypes and Chalk-Based Architectural Fragments

Throughout the project a series of chalk waste models explore the materials potential at a variety of scales. They test how the material could relate to the existing structure and how its qualities encourage specific spatial qualities.

Renovation Strategy: Key Elements and their Spatial Relationship

A renovation strategy makes most of the existing foundations, steel frame and roofing structure, whilst deploying chalk filter cake as a renovative infilling material, forming sculpted interiors and a fabric-formed envelope.

The Chalk House: Rolling Renovations

Chalk cob is a cyclic material. It can be altered by adding water and can return to the landscape easily. A new curriculum explores these advantages through establishing seasonal modules which alter a constantly evolving building and landscape.

The Chalk Works: Overview of Key Sites and Landscape Relations

The proposal makes the case for establishing various zones which teach lessons through their material and spatial adjustment. In its entirety, the school enables learning, temporary construction, landscape backfilling and experimental renovation.
