Interior Urbanism

Zhengxiao Wang

I was born in Jiaxing, a city of around four million people in eastern China. Before coming to the RCA I studied Environmental Design at Zhejiang University of Technology (ZJUT). My undergraduate experience taught me the basics of design and helped me discover my interest in interior space with its close attention to detail, meaning and narrative; and I went on to work for LYCS Architecture in the interior design department.

Since coming to London to study at the RCA I have tried to explore the connection between space and society. Discovering the stories and memories that contribute to space has always attracted me and led me to choose the Interior Urbanism platform for my second year, with a focus on mass observation and public space. Drawing, modeling, observing, debating, and thinking are activities that make up my approach. Using design thinking to help people change their negative or habitual attitudes towards space so as to generate positive social energy is my passion for design.

The Covid-19 pandemic has severely damaged the economy and atmosphere of Camden Town, and at the same time, it also highlighted the social significance of public space and the importance of re-gathering people. Looking through a space design method to re-activate this city is the direction of my efforts during the year.

I have tried to mix two different elements in this project to build a participatory, flexible, green public space, which aims to connect people in the community and reactive Camden Town in the post-epidemic era. The site is the historic Interchange warehouse alongside the Regent’s Canal. Once a place for the interchange of different forms of cargo transport, it will be reinvented as a welcoming public place. The building will house a gin distillery, an interior garden, and a community seed exchange to create employment, educational experiences, and entertainment.

Context of Camden Town

Camden Town is located on the northwest side of London, a fashionable and characterful place along the Regent’s Canal. Because of its open and welcoming community environment, Camden Town attracts a diverse group of people. Due to the impact of the pandemic fewer people come and the area has suffered commercially with many shops and restaurants permanently closed. This project asks: how do we reactive Camden Town in the post-epidemic era?

Residents in Camden Town have great enthusiasm for gardening and growing their own fruit and vegetables. Data shows that more than 900 people in Camden Town are on the waiting list for an allotment, but space is limited. In order to solve this problem, I plan to use the space of the canal. By recycling abandoned canal barges and replacing the middle seating area with a planted garden, they can become floating allotments. Barges can be linked together to form a larger shared planting space so that more people can be involved.

My site is the Interchange Warehouse at Camden Lock. This huge Victorian/Edwardian building in red brick framed with blue engineering brick has a rigorous architectural structure and plenty of delicate details.

A unique feature of the Interchange building is a basin that leads directly from the canal to the basement of the warehouse. This was once used for delivering coal and other materials and goods by horse-drawn barge, to be transferred to road or rail. Today the basin is used to take rubbish from Camden Lock to recycling on barges that enter beneath the building.

My proposal is that Camden’s keen gardeners dock their floating allotments in the basin where they can access plants and seeds, and contribute their own botanicals and produce to the gin distillery on the ground floor.

Growers’ Jetty
Growers’ Jetty — The dock in the basement, known as Dead Dog Basin, forms an exciting entrance by water. A floating timber jetty is used for docking the floating allotments so that gardeners can unload their produce, or visit to get seeds and plants. The ceiling of the basement is inspired by the original internal hoist, which enhances the connection between the two layers of space.
Seed Gallery
Seed Gallery — In the Eastern Vaults (former warehouse storage) there is a seed gallery with walls of timber shelves that provides areas for collecting seeds from growers in order to encourage sustainability and plant sharing.
Reuse Workshop
Reuse Workshop — This workshop space is dedicated to reusing the by-products of gin distillation, where waste is converted into useful by-products or new materials.
Central Greenhouse
Central Greenhouse — At the heart of the ramp is the central greenhouse, which provides special planting conditions for tropical plants. A pump set in the center of this installation uses water left over from the filtration and purification process.
Gin Distillery
Gin Distillery — Different from the traditional gin distillery's practice of putting function first while abandoning aesthetics, I tried to divide the production process with the ramp. The stainless steel pipe runs through the ramp, forming a brand new visual experience.
Gin Workshop
Gin Workshop — Gin Workshop with plenty of equipment provides proper working space for both staff and visitors. Space retains the walls and columns of the original building, and a small bar is set up in the upper area to sell the freshly produced gin and display the unique packaging of gin made by tourists.
Plants Market
Plants Market — A plant market is a place for growers and gardeners to exchange plants and share their experiences and knowledge.
Aroma Platform

Aroma Platform
Aroma Platform — The highest point of the space is the aroma platform, where tourists have a chance to overlook the whole space in the ramp garden.
 Staircase Park
Staircase Park — Staircase park is located in the southwest corner of the site, connecting outdoor allocation and plant market. Corten steel planters echo the indoor ramp, with a large number of green plants, they are not only adding green and vitality to the whole space but also strengthening its open and free space tone.
Lemon Garden
Lemon Garden — Standing on the corner platform of the ramp on the mezzanine level, visitors can enjoy views of the yard below while drinking a cocktail bought from the Corner Bar, made from lemons grown in a citrus garden below.

Inside the former Interchange, the building is a gin distillery park. The double-height ground floor hosts a distillery producing Canalside Gin, which is linked to a garden by a ramp, inspired by the pipes and stills of the distillery. As the ramp curves around the space, it provides visitors with the opportunity to walk freely in the double-height space. With the change of level and dynamic movement, visitors will experience a range of sounds, smells, and sights that will create vivid memories of their experience.


Originally the Interchange building would have been open at ground level so that goods could be loaded into delivery bays from rail and road. In recent decades the bays have been closed as the building has been turned into offices. In order to reopen the expansive ground floor, and connect it with the outside, I propose removing doors and panels and introducing natural light into the interior so that the plants can flourish. Both the interior and the external public spaces are filled with aromatic herbs and fruit trees which contribute to the making of gin and create a continuous green open space.


From the ramp, visitors have the opportunity to watch the process of gin distillation close-up and take in the aroma of gin and aromatic plants. The ramp also connects different parts of the production process: preparation is done in the basement, including the collecting and sorting of raw materials. Distilling and packing will be placed on the ground floor with special equipment. The final product - Canalside Gin – is being sold in bars located in three corners of the ground floor.
