PART 1: masters

the site chosen for the special project was the Leith Docklands - an area familiar to me from my year in practice, and a site with multifaceted issues. the site allowed the explore my interest in both urban design solutions at the waterfront and the re-appropriation of post-industrial landscapes.

taking over from the original masterplan prepared by RMJM in 2008, the aim was to design in more detail at a more human scale, with intentions of focusing on placemaking, exploring the themes of weather, oceans and particularly the local geological processes found throughout the Pentland Hills and the volcanic Arthur’s Seat.

the brief is developed as part of the project narrative to establish the conditions + aims, to measure the success of the final project outcome.

The aim of this special project is to investigate the post-industrial brownfield

landscape along the Edinburgh waterfront in Leith, and looks to consider ways to develop a

coastal public park infrastructure.

Using the existing regeneration masterplan as a base, I’ll be using up-to-date economic and environmental conditions to steer the project towards a more mixed development, with a focus towards wind/wave energy enterprise and job creation.

Key Focuses:

- guiding function towards a part in Edinburgh’s healthy living, social and cultural network.

- placemaking a civic waterfront parkland identity.

- post industrial + re-industrial land appropriation.

the final proposals transforms the waste site at the water’s edge, introducing a complex system of park, ecological process and social milieu across 800m meter of site. the industrial relics found over the site are retained and incorporated into a post-industrial civic landscape which prioritises activity and sport, using the size of the site to add a significant portion of greenspace infrastructure where it’s traditionally been lacking.

it makes connections to its immediate and city-wide surroundings and forms a long term growth and construction phases within a wider network of other waterfront developments and Edinburgh’s overall greenspace and lifestyle strategy heading into the 21st century.

accompanying the core masterplan and visualisations are working construction drawings and a planting strategy which focuses on key design features and interventions which define the project, following ideas of the industrial vs natural, existing local character and an ordered rigid plan around which a more abstract and evocative experience plays out.

humans are constantly fighting nature for control of the waterfront - what emerges is a gradient between two extremes, between totally managed human edges, or powerful natural processes claiming back the land.

coasts are environments of flux, as we’re seduced by the changing weathers and the tides, its dramatic ephemealities.

coastal flux is based on stewardship + management of ecological processes whilst enabling a park to experience these as part of the fabric of life.

concept: coastal flux

nearby Cramond Island is accessible only by a concrete path which reveals itself in low tide. this hide + reveal is an idea explored with the ‘bio dock’ feature and its island mounds.

process

our original task was to role-play a variety of characters which could inhabit the failed regeneration of Leeds waterfront, and developed for their own personalities, routines and needs - presented through the technique of experiential mapping.

using this site analysis method, as a small group we then developed concepts of urban design which responds to the problems and opportunities, developing them through sketches, 3D modelling and a physical ‘inhabited’ model concurrently.

the final solution used the ‘Dark Arches’ tunnel and used the train station to inform a design language of customisable, flexible and temporary carriage units 2x2x4m large to produce ephemeral spatial sequences.

Everyday Use

to demonstrate a flexible edge transition and social space, we developed a range of hypothetical spatial sequences based around 4 selected seasonal events, ranging down to informal, quickfire and improvised use of space.

we also went beyond the brief and developed an organisational body called “the friends of Granary Square” and modelled the roles and administrative background the landscape needed to function as we intended.

the “carriages” concept was the design of individual units which could be part-rented out on short leases, used for play, vegetation, retail, events and so-forth.

urban landscape planningparkwood springs, sheffield

this project focused on the theory of landscape planning at the city level, and dealt with the academia and theory of urban wildscapes developed by lecturer Anna Jorgensen and the seminal text; ‘design with nature’ by Ian McHarg.

the site dealt with a open ‘urban wildscape’ - a steep expanse of natural parkland, working wasteland and post-industrial environment without a coherent or driven planning agenda.

process

a two-part project, the first was to acquire, map and present census and topological data through arcGIS. this would inform the social basis of the subsequent urban planning.

then, using the designated theme of “transport and healthy living”, we developed phasing diagrams, programming graphs, a masterplan and some visual renderings of re-appropriating this parkland environment into a major local and regional activity centre.

i focused particularly on combining transport with healthy living, looking to cities like Munich and Duisburg to explore combinations of the themes.

year in practice2011 - 2012

in November, I received the LI award for the Future Visions: Open Spaces category at the LI awards. The submission expanded on my integrated project and suggested ways in which economic recession can be embraced positively within a community by maximising stalled spaces for better urban living.

part of the award includes a month work placement at LDA Design.

what was intended as a straight-forward 12 months of working in practice ended up a diverse meander through work and travel.

during graduation summer, I worked between making placement applications and producing competition entries - three of which had a degree of success.

Future Open SpacesMake the most of open space in towns, cities and villages

The Urban Corridor ParkAn adaptive approach to making the most of poorly used streets.The ProblemIn Britain, there has recently been a transformation of our cityscapes. ‘Millennium’ branded projects and the rise of shrines to the religion of shopping, retail and leisure were common throughout the country, resulting in a dense homogeny of consumerism.

When that dream began to fade in 2008, it took with it many of the shop fronts and industrial environments which supported it. Parts of our towns and cities are now peppered with boarded up shops and lie dormant.

As this was happening, there too was a type of cheap city environment which always had lagged behind - the pound shops and discount shoe outlets, which were at risk of segregation and disconnection with the rest of the affluent city.

As social mobility decelerates and wealth disparities wid-en, it’s important that such close city districts are glued together and share a common network of spaces which enrich the city centre as a whole - greater than the sum of its parts.

With the coming decades, the urban fabric has an oppor-tunity to reclaim these ‘dead’ streets, and make the most of under used spaces.

Pocket Parks

Stalled Spaces

The concept of a pocket park is not new - taking a small space and squeezing the max-imum impact out of it - was realised famously by Robert Zion’s Paley Park in 1967. Its principles were simple:

- A retreat from the noisy, dirty streets of Manhattan.- Slower paces, vegetation and a recreational attraction.

This report, published last year, explores the idea of stalled spaces (the underlying issue of this pro-ject submission),

Problems they cause:Environmental: overgrown, dangerous and det-rimental to the overall image of the wider area.Social: unpleasant for visitors, and despairing to residents and their quality of life Economic: hamstrings hopes of new attractions into a downward spiral of closures.

Opportunities:These spaces are in essence open canvasses for place-making, community engagement, de-velopment, green infrastructure, growth, education and temporary uses.

If these principles were applied in a way which connects spaces, rather than a reclusion, this would give a higher impetus to inhabit our streets, with a slower pace and a better appreciation for the surroundings.

Crucially, this is about making the connections through the city, over fragmented spaces connect-ed by unappealing streetscapes.

Precedents

A recent article illustrating the impact of a poor city environment, as affecting pedestrian footfall into a spiral of urban dereliction.

The SolutionThe idea of the corridor park, is to allocate a street, or stretches of a street, which are dedicated to en-hancing the site, and the surround-ing streets. It is essentially sacrificed, for the benefit of the rest of the area.

This could take any form, but has the potential to become a haven for:- Stormwater Catchment- Vegetation- Habitat creation- Social and Cultural Milieu- Environmental quality: Shade, Shel-ter and air quality- Recreation, Relaxation, Food + Drink- Allotments, Community functions or other senses of ownership.

Concept Model:How a Corridor Park would radiate its benefits outwards.

Brief + Fabric ConceptA conceptual way of examining the idea is through the idea of fabrics:- Connecting the dif-ferent threads, stitches and patches.

- Weaving in colours, textures, functions.

- Creating a cohesive end product which exceed the sum of its parts: a tapestry of con-nected users, charac-ters and functions.

The boost it creates, in terms of perception, a light-er streetscape, cosmetics, interest, desirability and quality of life will drive the economic investment in that area, whereas a partially derelict street would do very little to enhance its surroundings. In a resi-dential environment, the boost to the quality of life is significant, and would stretch lengths in curbing antisocial behaviour.

The benefit can potentially outweigh the cost of ‘sacrificing’ a flagging street - not just in the imme-diate recession phase, but for the long-term good.

As a route and connection, the park become a seamlessly transient space which helps to merge and create a gradient in character shifts from one neighbourhood to another.

To gain the maximum benefit of space, corridor parks works effectively when the area between two streets are claimed for use. In the example site, this is 40m wide.

The buildings contained in this space should be demolished or adapted to fit the needs of the new corridor park, with the waste material converted to landform or planting beds.

Small Scale:In small streets the site could become spaces for al-lotments or habitat creation, and extend the ideas built on by Pocket Parks, with wider benefits. This could be a school or other community regenera-tion project, along an allocated street.

Large Scale:The potential for the space to become distinctive socio-economic-environmental hubs and as part of the construction of the city is much greater, with a full design and consulation process.

The project is driven by the idea of the space and what it can offer to the area. The details of What, Who, and How, should be at the discretion of the site needs and context.

Theoretically, as long as the context is suitable, this can be applied to any settlement, as it has the flex-ibility to become whatever it needs to be.

PART 3: undergraduate

3rd year integrated projectdevonshire green, sheffield

combining Masterplanning, Urban Design, Planting Specification + Construction Detailing based around a single site, this project made projections to Sheffield’s future and attempts to respond as a fully working urban organism.

working from 1:2000 all down to 1:2, the task was to design solutions and futures in central Sheffield relating to concepts of a ‘big society’, economic downturn and social divides in a dense area.

process

the nature of the projects required a lengthy period of site research and early sketch plans where history and existing issues were clearly identified. once the masterplan skeleton was in place, Planting + Construction elements were introduced. these both insisted on delivering real-world, buildable solutions which introduced a clear visual character and personality, linking directly to the masterplan’s aims.

Yorkstone ‘Moselden’: Diamond Sawn 300mm X RANDOMmm X 50mm450mm X RANDOMmm x 50mm (Steps)Mortar: Light Natural Sand Joint MortarMortar Gap: 10mmSupplier: Marshalls

Moselden is used to create a light and natural character. The random lengths and swirls of texture contribute to a organic user experience.

Traditional Tegula is used to create the character of old market squares. The smaller size of the blocks creates a more detailed and human space.

Dark coloured granite is used to contrast with the step colour for better visual clarity, and flamed for a highly textured, gripping surface.

planting design

Colour: Herbaceous Perennials use Colour Wheel Contrasts.

Colour: Crushed Rubble planters use Earthy and Warm palettes, punctuated with occasional variations.

Layer 3 - Dominant Grasses: Stipa, Calamagrostic, Cortaderia, Verbena, Earthy, Wind Animated.

Layer 3 - Stipas : The gradual introduction of Stipas and small ornamental grasses creates an intro/outro intro the main grasses area.

Layer 2 - Grasses + Umbels: Carex, AchilleasStrong forms, mid level bushy grasses.

Layer 2 - Colourful Perennials: Echinacea, Digitalis, Angelica, AchilleasStrong forms, mid level bushy grasses.

Layer 1 - Groundcover: Panicums, Sedum spuriumEvergreen groundcover and low level Herbacous Perennials

Layer 1 - Groundcover: Panicums, Sedum spuriums. Evergreen groundcover and low level Herbacous Perennials

Texture: Water’s edge, damp soils calls for large, blocky foliage for interest from a distance, particularly from the other side of the waterbody.

Leaf surface rain retention adds to sense of ‘the wet’.

Texture: As a linear user experience, all plants (inc. Prunus) are selected for their fine / thin textures for close-up interest, and to maintain visual permeability across beds.

Residential Housing Landscapes‘Living Around Water’

BriefTo develop a housing scheme from the landscape upwards, to meet a density quota and to take a certain aspect of sustainability and building that into the design.

Context + DesignDue to the steep topography of the site, I felt it necessary to incorporate a high quality drainage scheme which becomes the focal point of the scheme.

FeaturesIt also converts the road into a shared surface, prompting a safer and easier living experience, with parking, waste disposals, a local shop, allotments and both open greenspace and woodland.

MasterplanningSharrow, Sheffield

Brief

Sheffield’s Sharrow district has its ties to its (very close) city centre severed by a wide ring road. Its distinctive features ( river corridor, tower-block open space networks ) offered a chance to turn low socio-economic values into positive and better connected spaces.

The masterplan develops identified opportunities into a workable street fabric through screening and pollution mitigation, as well as amplifying greenspaces and boosting connections with its neighbours using the existing green and blue networks.

Land Contamination

Brief

To produce a conceptual model of how the restoration of a plot of contaminated industrial land can be restored.

The site’s bitumen processing history was investigated to identify the nature and extent of the pollution.

Then, real-world solutions for how to process this information was gathered, to form a strategy for the restoration process.

Finally, using classic case studies like Duisburg-Nord and Gas Works park, practical and profitable solutions were developed to transform this canal site into a habitable space.

Document WritingEnvironmental Impact Assessment

Brief

Produce an EIA for an opencast coal mining operation in rural Yorkshire, England.

The document introduces what an EIA is, and draws on local development frameworks (LDFs) to contextualise the character of the subject of Yorkshire.

Site maps and photographs were researched and used in the 26 page report, which includes Zones of Visual Influence (ZVIs)s and Visual Envelopes which accounts for all potential impacts, receptors + severities.

It concludes with a post-mining mitigation and restoration strategy which converts the land into parkland for the local populace, drawing on similar case studies in the area as an indicator of its viability.

Conceptual Design StudioSheffield Cultural Industries Quarter

Brief

This conceptual design studio took an up-coming area of culture and activity, and required a design of the cultural industries quarter which defines the space.

Produced in two halves; the first - end of semester exhibition - heavily incorporated art, A/V, 3D models and display pieces, completed in a group of 3.

The second, solo half took a segment of the site and detailed the design of an area 20x20m, based on its intended functions and context.

north america, 20126-week coast-to-coast trip. inspired by the book ‘taking measures across the American landscape’ (J. Corner / A. S. Maclean), I wanted to use this opportunity to understand the nature of landscape architecture across the Atlantic. using cars, planes, trains and engaging with the landscape, I saw the range of social-environmental -economic issues affecting the States today.

west europe, 2012i spent 4 weeks in the summer inter-railing, using the opportunity to explore and visit the landscape + architecture projects which I’d studied. these ranged from contemporary parklands to the ‘classics’ found around Italian villas.

i was particularly interested by 2 ideas - first, the post-industrial projects which dominate Germany. second, the use of sustainable, human transport networks (cycle frameworks, pedestrian design etc.) which would go on to inform my MLA special project sites.
