View of the scheme’s key community open space: The Campiello

The site location & its relation with the green infrastructure network

The Green Web strategy plan

The Strategic Green and Open Spaces Review Board Report from 2016 identifies the ‘‘Green Web’’, a network

• f green corridors that covers large areas of the city and links them.

The analysis convers three layers of information collected. The strategic position of the site can allow to re- establish immediate connection with the river and it can help extend the green corridors network as a future long term plan. Making the site a public green area will contribute to create a higher quality and more attractive environment for the local communities to enjoy.

Key issues in Mossley Hill area

Low number of key community gathering centres marks further social isolation across Mossley Hill Key centres causing traffic congestion due to their location along the outskirt of Mossley Hill perimeter The site strategic and central location is the most affected by traffic congestion as it is located on secondary roads

Reference: Number of residents accomodated in high density terraced houses adjacent to the site, which were taken into consideration.

VENICE’S URBAN CONDITION: THE CAMPO & CAMPIELLO PUBLIC DOMESTICITY

CAMPO CAMPIELLO

CAMPO: The name derives from the fact that in ancient times these spaces were real meadows for grazing or cultivated as a vegetable garden. Later in the years, the fields were

• paved. The campo was the Venetians’ social epicentre for several activities such as commercial markets, playgrounds and community gathering events like religious cerimonies

CAMPIELLO: A smaller version of a Campo. It often possess a well located in the centre as the main source of the city’s water supply, through the filtering of rainwater. The campiello defines a micro-community neighbour which stimulates interaction and intimacy among the residents.

Circulation and built environment

I have analysed the typical Dutch Canal housing as it was developed in the 18th century and still remains intact, thanks to the hierarchy that establishes between private, semi-public units access and public paths & traffic. It is intriguing how it deals very carefully with privacy and defines a clear distinction between public and private. The stairs are part of the dwelling but also become a communal semi-public space. Therefore, they can be introduced into the scheme’s design. The main feature of this type of housing provides the access entrance through an elevated ground floor, the souterrain/basement is reachable from the street level and the unit possess flexible open plan layout.

Strongest and weakest areas

Natural lighting conditions studies on site development area

The study demonstrates that North/South aligned blocks can benefit more from daylight coming from East and West. The blocks open up in circle towards South in order to create green courtyards that profit from Southern daylight. . The scheme’s aim is to build around the existing landscape to avoid any damage to it and it can be built on the existing buildings footprint in order to maximise daylight use. Since the trees vary in heights, types and are mutable with aging, they cause

• vershading in particular areas which are not ideal

to build on. Secondly, in order to preserve the existing woodland, the design is intended to touch the ground lightly. Therefore, a great opportunity is to build on the existing buildings’ footprint and to use green roofs in order to give back to the site the footprint which has been taken off. Thanks to the study below it has been possible to identify the strongest and weakest points of the selected buildable area, in order to plan better the buildings’ position, orientation and seasonal vegetable gardens locations to maximise daylight use. Areas which profit the most from natural daylight Areas most affected by stark shadows

Current buildings’ footprint & selected site area for development

BUILDINGS ORIENTATION: 45 DEGREES - 70% solar gain (BEST OPTION)

• 1. Evening sun to be avoided as it can cause glare and overheating during

summer time. But ventilation needs to be maximised as prevaling winds come from West.

• 2. Mid-day Sun entry is maximised as it is the strongest during winter times.

Solar shading devices needed against direct summer sun.

• 3. Morning sun maximised as it offers pleasant teperature during summer but

it is cold during winter. BUILDINGS ORIENTATION: 90 DEGREES - 50% solar gain

• 1. Morning sun can enter it offers pleasant teperature during summer but it is

cold during winter as it arises late.

• 2. The most advantageous mid-day Sun entry is blocked as the units are

arranged in line.

• 3. Elevation exposed to evening sun which provides high temperatures during

summer time and can cause overheating.

Maximised solar orientation of the units Define a hierarchy of spaces

Central semi-public communal open space in plan Distinct appearance can define different ownership of spaces, whist community collectivity is being kept thanks to the visual relation with the common central

The dwelling’s back garden acts as a transition space between private & semi-public space Visual connection to be kept between the semi-private unit garden & the common open space Change of levels at the front of the units can ensure privacy whilst define distinction between public and private

Orientation studies to maximise daylight use

OPTION 1 - 90 Degrees North/South units OPTION 2 - 45 Degrees angled units 17:00 pm - March 17:00 pm - March 09:00 am - March 09:00 am - March 13:00 pm - March 13:00 pm - March

The model testing demonstrates that a layout that proposes North/South aligned blocks with 45 degrees angled orientated units can help maximise the daylight use in the buildings. The blocks are supposed to profit from West and East sunlight, instead they just profit from Southern sun and overshade on each

• ther’s. Careful considerations should be made on choosing the right distance between the blocks in order to avoid this.

Following the existing buildings’ footprint and predominantely using North/South aligned blocks with 45 degrees angled units towards South, the scheme allows all buildings to profit from daylight, views and communal open community spaces. The landscape and trees are totally preserved, not damaged and the existing open green spaces can become cultivable seasonal farming as they profit from daylight all day.

Wall construction Timber lightweight studs structure with hemp insulation, OSB board and Waterproofing layer. Horizontal timber cladding screwed to pre-treated vertical and horizontal timber battens to create a ventilated air cavity behind the cladding system. Fiber cement board on façade to be screwed on vertical battens and cover the blockwork. Floor construction Steel screw foundation piles have been chosen to avoid the foundations to remain permanently in the ground. This system allows the structure to be totally demoutable as the screw piles can later be unscrewed, if needed. Perimetric blockwork to sit on top of the supporting steel grade beams grid in contact with the ground, to create a ventilated void. Suspended floor system (Floor joists with hemp insulation) to sit on top of blockwork via a floor plate. This will be followed by the OSB board, vapour control layer and finished interior flooring. From an exploration of bio materials, the construcion system is intended to be 100% diassamblable and recyclable
