‘TRANSITION’ Research into the site revealed that a large proportion of the space designated for the new park flooded every year. In addition, along the entire boundary to the west runs a railway. These two physical events formed my early thinking for the park, both for its construction and planting. My aims were to create a diverse, adaptable and dynamic landscape, visitors are confronted with sustainability and biodiversity, where they can observe and learn about the impacts of climate change, that offers multiple and differing spatial experiences and journeys, a space that is fluid, surprising, changes over time.
SITE VISIT: NEWARK EXISTING HARD MATERIALS ON SITE:
LANDSCAPE CHARACTER:
The hard materials at Newark have a strong connection with Newark’s character, giving the town a sense of identity. Materials can be associated with place.
“Landscape character is the set of attributes, both tangible and intangible, that define an area in much the same way as looks, personality and behaviour define a person”
In my design, I want to use some of these materials that can be seen in Newark to keep the character as well as reduce costs as these materials would be locally sourced.
- Waterman, Tim, ‘The Fundamentals of Landscape Architecture’, Fairchild Books, 2015
Newark is an ancient town. Evidence of this can be seen through not just the town’s architecture but also hard materials such as paving. The ‘cobblestone’ paving settes in Newark Royal market have been eroded over time. This gradual process that happens over a long period of time can be compared to the river erosion that is increasing due to the effects of climate change and how we can prepare resilient landscapes through design and choice of materials.

The plan can be seperated into two different uses of space. The path provides linear movement with attractive views of the Meditteranean planting beds and bespoke Corten steel detail either side encouraging slower pace. The natural stone paved area with gabion basket seating provides an area of rest and relaxation with bespoke paving detail creating a smooth transition from hard to soft. This area acts as a focal point for visitors. The steps are at the intersect of these two spaces providing a level change.
TUTORIALS: Feedback from tutorials helped me progress my ideas and make changes to improve my design.

DETAIL 1: GABION Gabion Basket SeatingBASKET SEATING
AUTOCAD: My experience with AutoCAD has been a challenge
Materials:
GABION BASKET SEATING SKETCH: CORRECTION NOTES:
Geotextile layer is needed (50 mm width non-woven geotextile fabric). This will prevent soil from infiltrating the gabion baskets in front.
FSC Timber Place more timber boards along the backrest to increase comfort. Hornch not needed Gabion Basket: Recycled Infill Material & Galvanised Steel
INFILL MATERIAL: Hand fill gabion with two different types of infill stone. At the back of the gabion, fill with recycled product such as building rubble (brick or limestone) and at the front a more aesthetically pleasing materials such as a limestone infill.
CONTRACTORS NOTE:
Drawing Not to Scale
Not necessary to place stone paving underneath gabion basket bench to reduce costs as it will not be seen. Instead put a concrete foundation underneath to ensure stability.
500 mm x 500 mm x 500 mm hand filled gabion basket. Two different types of infill stone: recycled gabion fill at back of gabion (50-150 mm nominal size) and grey limestone infill (100 mm nominal size). All panel intersects are to be laced with wire matching gabion mesh.

GABION BASKETS:
As shown in the image above, various stone textures and colours can be used for gabion basket infill to provide a more aesthetically pleasing front face.
In this image, variation of stone sizes have been used to create a differtent visual effect.
Gabion baskets were traditionally used for river/coastal defense. Contemporary uses include gabions as retaining walls and seating spaces.

GABION BASKET FIXINGS FIXINGS:
CORRECTIONS:
This stage in the design was challenging as there were a number of attachments that were needed to fix the timber boards to the steel structural frame and then in turn, fix all components to the gabion basket mesh to complete the seat.
• • • •
I will not be able to have the attachment from underneath as the gabion will need filling first. What could be done instead if I were to bolt (not screw) them, except the backrest ones which can be screwed from behind. A washer is needed underneath each bolt to aid attachment and allow for thermal movement. M10 bolts (10 mm in diameter) probably too large, this could work with M6

4 m wide Earth Friendly Concrete (EFC) path STEP DETAIL VERSION1: The image shows an example of how my step detail might have looked if I were to have a gabion basket retaining wall either side of my steps. The planting on top of the steps break up the hard landscape.
This CAD drawing shows the step detail with a gabion basket retaining wall and stainless steel handrail. I decided that a handrail wasnt required for my design as there are only 5 steps.
STEP DETAIL SKETCH:
For my design, a handrail is not needed as maximum number of steps is 5. A retaining wall either side of steps will act as support when descending/ascending steps.
CORRECTIONS:
Insert a slot drain after corduroy paving units. Check out supplier: Aco Drains.
Ensure that the concrete hardcore is 200 mm
Drawing Not To Scale
Steps and subbase both made out of concrete therfore no need for 50 mm mortar. If steps where made out of stone, mortar is needed.
A252 reinforcing steel mesh (6mm bar at 100 mm spacing) is needed running through the middle of the concrete to provide extra support.
DETAIL 3: BESPOKE PAVING UNIT Bespoke Paving Detail: This is my first attempt at trying to construct the bespoke paving detail for my design. An uneven edge which extends out to create a smooth transition between hard and soft, I had one stone paving unit set within the planting bed. However, this wasn’t an appropriate approach to take as the paving unit sits loose and may get stolen as has it has nothing fixing it to the ground.
Not to Scale
The paving is held in with a concrete haunch to prevent damage to the edge of the paving unit.
Slabs PRECEDENT STUDY: NY HIGH LINE HIGHLINE UNDER CONSTRUCTION: I did research to try and find construction plans for the High Line to gauge dimensions for paving units, however I was unable to find specifics. On the HighLine website, there are constructiuon detail images which gave me inspiration for my design.
The High Line stone paving unit is held in place by the weight of the stone itself.
Natural Stone Paving Units
BESPOKE PAVING DETAIL: This is my bespoke paving detail. It resembles the same shape but different dimensions to the High Line paving units.
High Line, New York - Construction Detail: Paving High SlabsLine, New York - Construction Detail: Paving Slabs
BESPOKE PAVING DETAIL SKETCH: CORRECTION NOTES:
DIMENSIONS
THE EDGE
The paving unit length dimensions need changing. The standard length for a single paving unit is 900 mm. I need to cut back by 750 mm. Anything bigger than this is costly and this also reduces amount of waste product produced. It is 75mm thick and 300 mm wide.
The bespoke paving unit on the edge has the same length but a different width and 100 mm thicker to maintain weight but also allow for a 200 mm spacing between each unit for plantring to grow.
FINISH Flamed finish will provide a non slip surface.
COLOUR The paving will be arranged in bands of different colours. 1/3 light grey, 1/3 silver grey and 1/3 dark grey. This will provide variation and interest.
MATERIAL The paving units will be made out of granite (igneous) as it is a cheap, economical material. The crystaline means it is less prone to cracking.
DETAIL 2: BESPOKE CORTEN STEEL DETAIL AND PATH CONCRETE PATH: The concrete path provides an alternate material to the natural stone paving setts I have in my design for one of my details. The concret will be C40 Earth Friendly Concrete (EFC) which is replaced with a binder system made from anchemical reaction of 2 industrail waste byproducts. This creates 90% less carbon dioxide than conventional concrete. The concrete will be poured in situ for ease as it is covering alarge surface area and to reduce costs.
CONTRACTORS NOTES: 4000 mm x 10000 x 150 mm of C40 Earth Friendly Concrete (EFC) poured in situ. Textured through mechanical brush finish.
CORTEN STEEL PLATE & FIXING: 15 mm (thickness) folded Corten steel plate. M10 (diameter) bolts with chemical anchor fix plate to concrete subbase.
Concrete foundation needed so that the corten steel sheet has something to fix on to. Reinforcement mesh is not needed as the weight of the concrete itself will support the corten steel.
RICHARD SERRA & CORTEN STEEL
ORGANIC SHAPES: Richard Serra’s work with Corten steel was my inspiration for my Corten steel detail. What interested me the most was the way in which Serra manipulates the materials by bending it into organic formations and placing them into the landscape. His pieces are at a large scale which increases the impact of his work.
CORTEN STEEL PERFORATIONS: Corten steel plate has a bespoke pattern which is plasma cut into the sheet metal to provide additional pattern/ texture. Perforations reveal planting behind allowing people walking past with a more intriguing journey along the path combines both hard and soft landscape together.
PERFORATIONS TEXT:
CONSTRUCTION NOTE:
I have chosen to use phrases from a poem by William Wordsworth as perferations on the corten steel sheet. Text will reflect Newark’s rich cultural and historical past and provides visitors with a lasting image of what Newark’s landscape once was.
Subbase should always should always be constrcuted underneath concrete for stability.
‘YARROW REVISITED’ BY WILLIAM WORDSWORTH I read ‘Yarrow Revisited’ which touches on Newark’s landscape. A few key phrases from the poem are listed below: ‘breezes played, and sunshine gleamed’ ‘quiet contemplation’ ‘The freeborn mind enthralling’ ‘day of happy hours’
ELEVATION OF CORTEN STEEL PATTERN
Materials:
Corten Steel
The corten steel contrasts nicely with the other materials selcted as the sheet material is not made up of a grid/linear structure. It’s reddish/brown warm colour contrasts with the cool grey colours of the natural stone, timber and gabion basket recycled stone rubble.

Site appropriate materials are used throughout. This detail retains Newark’s rich cultural and historical past by using materials that are familiar to the area as well as updating, introducing new materials. Gabion baskets are selected as a key response to river flooding and work well with moving water which can be seen in other areas of the park. Repetition of certain materials creates design coherence. Materials are suited to a 2050 climate. Where possible, materials embrace environmentally friendly techniques, such as the concrete path which will be poured in situ, and will be C40 Earth Friendly Concrete (EFC) which creates 90% less carbon dioxide than conventional concrete. FSC timber with a planed finish, is a hardwood which will ensure longevity, is used for the gabion basket bench. Recycled infill material will be used for the back fill of the gabion basket and all materials will be locally sourced and sustainable.
