Shell.

Shell explores how discarded seafood shells can find new value in furniture design.

Inspired by London's seafood culture and traditional shell craftsmanship, I experimented with shell-based materials before developing an oak jewellery cabinet with textured shell-concrete surfaces.

Localism · London furniture

What makes furniture belong to London?

Furniture making in London is squeezed by high production costs and cheap imports. I looked for a local answer: London materials, simple making and a sense of place.

So much seafood also means shells. What if they became a resource instead of waste?

The story in three threads

A material, a tradition and a form.

Shell tied the cabinet to London in three ways, and each one shaped a different part of it.

The cabinet sits where the three meet: waste material, precious tradition, everyday furniture.

Waste · the material London throws away

Thread · Waste

At London's markets, shells leave as waste.

At Borough and Billingsgate I asked where the shells go. They leave with the morning's rubbish or as fertiliser, never as a material.

Field notes · Billingsgate

“In the busiest morning market, a lot of rubbish is generated as traders divide and handle seafood such as fish, shrimp and scallops.”

Market Control member

The rubbish is hard to clear from the riverside site, so a waste-clearance company collects it the same day.

“Most of these seafood scraps are used as natural fertiliser in London.”

My proposal

A loop instead of the bin.

Collect shells from vendors, cast them into tiles, build furniture, and return a share of each sale to the vendor.

Looking at shells beyond the market.

After finding discarded shells at London's seafood markets, I began looking at how they had been used and collected. My research took me from shell-covered buildings to decorative objects and natural-history collections.

The shell huts brought this research back to London. Their decorated walls enclosed a practical space used to store gardeners' tools.

Shellwork

Individual shells were carefully arranged into flowers and decorative patterns. These objects interested me because of the time and craftsmanship given to a material I had encountered as waste.

Natural history and collecting

Conchology books recorded the shapes and distinguishing features of shells. They offered another way of looking at the material: as something to examine, identify and collect.

The decision

Choosing a jewellery cabinet.

The care given to shells in these references informed my choice to make a jewellery cabinet. I wanted to use discarded shells in an object made to hold things that someone values.

Material · keeping the shell visible

Threads 01 + 03

Hard enough for furniture, and still showing the shell.

I crushed shells into fragments and tried four binders. Each card shows the sample from that test.

Why concrete

Shell is calcium carbonate, the mineral in cement's limestone. Raw concrete is also London's own surface.The Barbican, Brutalist London

Form · where the shell sits on the furniture

Thread · Form

A familiar form, a distinctive surface.

Inspired by the proportions of mid-century long-legged cabinets and the use of embedded materials in furniture surfaces, I explored how shell-concrete tiles could become part of a compact oak jewellery cabinet.

Through sketches and material placement studies, the design evolved into a tall, slender cabinet combining a familiar furniture silhouette with a distinctive surface.

A familiar cabinet form, reinterpreted through shell-concrete surfaces.

Oak carries the structure and the shell stays on the surface. Concrete is heavy and brittle, so as panels it keeps the cabinet light, and a broken tile can be replaced.

Making it saleable

The first prototype looked like a student model.

After studying how cabinets are made at Aram and SCP, I rebuilt it to a sellable standard, testing each detail on sample pieces first.

Prototype

Screws, plywood, a broken tile

Exposed screws and hinges made the prototype look handmade rather than sellable. During installation a concrete tile fell and broke, so I moved to a harder concrete mix.

Body

Rebuilt in solid oak

I cut the oak into 2.5 cm boards, planed them down, then cut two 20 cm and two 24 cm lengths. The sides are glued into a box, with no screws showing.

Hinges

Tested on sample pieces

In the first test the hinge sat outside the cupboard and looked unfinished. On the final piece I fitted a more ornate, old-fashioned hinge that adds a sense of age.

Door

Magnets instead of push catches

A push catch looked out of place on a classic cabinet, and pressing it tipped the tall cabinet over. Old cabinets at the furniture market used magnets, so I did too.

Finish

Glue, sand, wax, dry

The body was glued and clamped, then sanded. Hand sanding was slow and uneven, so I switched to a sanding machine. Wax oil makes the oak waterproof and mothproof and brings out the grain.

My part

Individual project, from market to workshop.

  • ResearchMarket visits, shell history in London, localism and circular economy reading.
  • MaterialBinder and mould tests, the shell-concrete tiles.
  • DesignSketches, renders and dimensions.
  • MakingOak cabinet, doors, concrete top, finishing and fitting.

Looking back: I started from which binder to use. Starting from the shell's own ridges and texture might have opened more forms. I also proposed returning part of each sale to the vendors who supply the shells, which stayed untested.
