Project development - Flooding Peckham

This was my idea for my second plan-proposal which revolves around Peckham potentially flooding.

After doing more research I began to get interested in how the waters evolves in South London. With this I thought I could back-up my idea of bridges even more.


Stage 1 DARK BLUE : reaching a water depth of 3m in 2080

Stage 2 LIGHT BLUE : reaching a water depth of 6m in 2140

Stage 3 GREEN : reaching a water depth of 9m in 2200

Based on several prediction maps I created how the floods could overcome Peckham over a stage of three times 60 years which is the life span prediction of a buidling. The level of the waters rise every year and if the prediction of the National Climate Assessment 2017 are correct, they announced that by 2100 the sea level could rise by 2.5m. The elevation of water is mostly due to the rising in temperature which melts the ice expanse the water and causes more and more rain to fall. Peckham is what we can call a combined flood area.


Surface waters are from streams, rivers, ponds. The high risk path flowing down Peckham Rye Common, follows the old River Peck.

The rain falls on an average of 55mm yearly, which could increase due to climate change and therefore enduce more flooding.

The flood depth at high risk can range from 0.5m to 1.0m.

The flood depth at medium risk can range from 0.25m to 0.5m.

The flood depth of low risk can range from 0.1m to 0.25m.


The event of the reservoir flooding remains low. This could be due to prolonged heavy rainfalls, poor maintenance or a leak.

If it were to happen, it would release a large amount of water rapidly flooding a large area.


My action plan is layout out into three stages that are relevant to the floods that could be happening over the next 180 years.

To work as sustainably as possible without destroying the current housings, I chose empty sites, car parks and industrial areas in order to build the future buildings.

To link the future buildings, I propose to build bridges right above the current urban fabric, which would be 12m above ground as it is the average building height in Peckham.

To try and save as much as possible Rye Lane, which is the heart of Peckham, I suggest digging a central Canal where the road is. This would contain the floods allowing Rye Lane to be pedestrian and to keep the commerces alive and protect the heritage.

Contact between bridges and ground are important to keep Peckham’s Identity and life. They are placed at the key points in Peckham. The forst one is North of Rye Lane’s future canal, pedestrian zone and commerce. The second one is the Train Station, as it will still be usable since it is above the floods. And finally, the end of Rye Lane commerce, important node which connects to the rest of the city.

As most of the parcs in the center will be flooded, I suggest creating new elevated parcs which link with the bridges.

This Elevated Peckham will create a new rhythm.


After my last review, I found out that as London's land is too precious they would never allow flooding to happen. They already have one Thames barrier and are planning to build a second one to control the rising waters.

This information lead me to go back to my initial idea and refine it.
