4The following document supports a portfolio that proposes a Hostel and associated buildings including a Community Hall, Cottage, Stables and Farrier Enclosure located in Stonehenge. The buildings are located 800m east of Stonehenge along an existing footpath/bridleway.
Thesis:
Stonehenge was most likely built by farmers and herders who would have had a strong reliance on animals especially horses.
My thesis is based on the theme of encouraging interaction between humans and horses, relating back to the ancient agricultural lifestyle of the Neolithic community.
I am proposing a hostel library to educate guests about the ancient landscape and motivate them to explore the wider context, rather than just Stonehenge it self.
5Architectural Intention
Pitched roofs are a common site in Wiltshire. In this proposal I have explored the articulation of pitched roofs which give the sense of a small village or community. The roof structure is formed of Oak trusses which are revealed internally. The oak trusses sit onto brick walls which are also revealed internally. Thin cast iron columns support the span of the trusses.
Externally the building is clad with wide oak panels which give the building organic qualities which allow it to exist without disturbing the natural context. The fixed windows sit between horizontal bands of
locally sourced flint stones set into mortar.
Copper is a dominating material used throughout the proposal. It is used as a roof cladding as it provides an economical, long-term roofing
solution. Its low life cycle costs are attributable to the low maintenance, long life and salvage value of copper. Through its natural weathering process, the warm bronze colour turns to an elegant green finish.
Copper is also used on the door furniture and other internal finishes,
this is due to its antiseptic qualities. As this proposal is based around the human relationship with horses, there does not want to be an issue with bacteria and germs.
The existing footpath/bridleway is lined by a dry clunch wall. Clunch stone is locally found in the Stonehenge area. This wall continues to form the boundary for the paddock and then continues again to form the farrier enclosure.

7In terms of archaeological importance, Stonehenge is one of the most important
places in the world for studying the neolithic period. The world heritage site
of stonehenge and surrounding sites includes many examples of well preserved structures and landscapes that were used
for temples, burial grounds, landmarks, calendars, defences and with some uses
still currently unknown.
Stonehenge itself represents over 800 years of construction from a defensive ditch
to wooden structure to an assemblage of stones sourced from both 19 miles
and 150 miles away. It demonstrates the sophistication, ambition and foresight of
iron and bronze age man.
The surrounding world heritage site of 2600 hectares contains innumerable cases of
different sites also important to this period.

8These two ancient sites are over 15 miles away from each other. It is very likely that they would have been related to each other thousands of years ago. But gradually the connection has dwindled and there is no clear route connecting them. This is probably due to their decreasing insignificance.
As it stands they are partly separated by a large area of MOD land which is not very accessible. None the less, it seems wrong not to connect these sites as part of my wider landscape proposal. This has already been attempted by a group called the Friends of the Ridgeway who have planned a long walk from Avebury to Stonehenge.
I came to notice many bridleways on an ordinance survey map of the area. I also discovered when travelling between the two world heritage sites a large white chalk horse on a hill in Pewsey.
There is a clear love of horses in Wiltshire, therefore an appropriate way to connect the sites would be a planned bridleway bypassing all three white chalk horses (as indicated on the map).

9West Kennet Long Barrow
I have sketched ancient sites in Wiltshire in order to understand the wider context of the site.
West Kennet Long Barrow is a Neolithic tomb, it is built from stone and split into chambers. It is formed underneath a mount of earth. I sketched it in plan and section by pacing out the approximate measurements.
In section it formed a very interesting cut into the ground. The interior was lined with dry stone. The plan seems to me to have adopted the shape of something organic growing from the ground. Perhaps this interesting concept could feed into my spire proposal project.
10
I undertook a small light study inside Salisbury Cathedral. I drew an elevation and section of a niche at 2:00pm. This analysis has helped me develop my project and gain an understanding of natural light and the effect it has on crevices and the atmosphere of spaces.
11
Ground Conditions - Avebury
Sketching in detail, interesting ground condition transformations in the town of Avebury WHS.
The granite setts have a rough texture and they weather very well. Changes in ground conditions define boundaries. In my proposal I have used different ground conditions which provide different experiences when walked on. Therefore define the activity that takes place on it.

Phenomenon Sketching - Hogsmill River
Here I was interested in timing precise moment, focusing on a detail of a droplet of water falling into the river.
I found this particular element interesting because I found the beauty in something ordinary.

The Avenue leads from the main entrance of Stone-henge and tracks the original path of the transportation of the stones. Little trace remains, but the site is still of archaeological importance. When approaching stone-henge from the avenue the view is partially hidden lead-ing to a dramatic reveal.
Stonehenge itself is cut off from its landscape by the A303 road. The car park it leads to and the road itself is very busy and detached from the soft sloping landscape of the site.
The barrows contain the remains of the great and rich from the iron and bronze ages. Items of gold and pottery were found buried with the remains.
Woodhenge and Durrington Walls are sited north east from Stonehenge. The concrete posts represent the posts of a tall henge the was used as a sacred space. The land surrounding leads to a huge defensive mound called Durrington walls which protected the henge from intrusion.
A cursus is a long earthwork surrounded by a shallow ditch that sits in the landscape.A rare monument, its function is unknown but has been attributed in the past to Roman chariot racing because of its long track like appearance.

It is noticeable that the landscape has not changed much in over 100 years. This may be due to the fact that it is hard to get planning regulation in such a historic landscape.

Development, Precedent Studies and Research

Inspiration
A precedent study for this proposal is a Victorian warehouse in Shropshire. The rough brick interior has a beautiful rawness about it. It seems to be weathered, almost as if the building has been turned inside out.
The rich timber roof is lightly sitting on the thick solid brick wall. Thin cast iron columns seem to be pinning the light roof structure down instead of holding it up. This abstract view is explored in this proposal.

Farriers
A horseshoe is normally made of metal and is designed to protect a horse's hoof from wear.
The fitting of horseshoes is a professional occupation, conducted by a farrier, who specializes in the preparation of feet, assessing potential lameness issues, and fitting appropriate shoes. In the United Kingdom, horseshoeing is illegal to perform without specific qualifications and experience.
The most common horseshoe materials are steel and aluminium, but specialized shoes may include use of rubber, plastic, magnesium, titanium, or copper.
The Process of Shoeing:
- Old shoes are removed using pincers
- The hoof walls are trimmed to the desired length with nippers
- The sole of the hoof with is shaped with a hoof knife
- Shoes are then measured to the foot and bent to the correct shape by placing the metal in a forge before bending it on an anvil. This method gives a better fit
- The hot shoes are put into water to cool
- The shoes are nailed into the hoof wall at the white line of the hoof.
- Sharp points of the nailed are cut using a clinch cutter
- A rasp is used to smooth the edge where it meets the shoe and eliminate any sharp edges left from cutting off the nails.
Pincers
Rasp
Hoof Knife
Clinch Cutter
Forge Anvil and Hammer
The forge is used by the farrier to heat a metal horse shoe so it becomes malleable in order to shape it to the particular horse.
A forge typically uses bituminous coal, industrial coke or charcoal as the fuel to heat metal. It is a fire that can be controlled be a particular balance of air, fuel, and shape of the fuel/fire.
Features of a forge:
Tuyere a pipe through which air can be forced into the fireBellows or blower a means for forcing air into the tuyereHearth a place where the burning fuel can be contained over or against the tuyere opening.
During operation, fuel is placed in or on the hearth and ignited. A source of moving air, such as a fan or bellows, introduces additional air into the fire through the tuyere.

Dry Stone Walls
Dry stone walls are constructed from stones without any mortar to bind them together. Dry stone structures are stable because of their heavy weight and carefully selected interlocking stones. The wall/fence that surround horses need to be at least 1450mm high.

Kizhi Pogost - Investigation
I have investigated a landmark wooden structure - Kizhi Pogost Russian Church. Specifically looking at the construction techniques and showing them in models and drawings.
The Kizhi Pogost Russian church is made from logs that are inter-joined. The building transforms from a cruciform shape in plan to an octagonal shape.

Red Lion Hotel, SalisburyExternal Space StudyCourtyard Area : 588 sq m Scale: 1:1500
This courtyard is an obvious example of an external room. The area is lined by high walls on all sides. Here you feel safe and protected from the ele-ments. Tables and chairs clutter the floor space and plants grow up the walls. The vast amount of plants and bushes make the space feel more organic.

Tithe Barn, Bradford Upon AvonHall Space StudyInternal Area: 566 sq m Scale: 1:1000
I have looked at the Tithe Barn not just a study of a community hall but as an arrangement of buildings.
The buildings are very spread out but they all seem to be surrounding and feeding the view towards the Tithe Barn.
The size of the Tithe barn is a lot larger than an acceptable size for Stonehenge.

My proposal starts with a long dry clunch wall which runs along an existing footpath/bridleway from the main road. This
wall eventually forms a cluster of buildings. The wall forms the boundary for the horse paddock and also forms the
farrier enclosure and forge.
The hostel has views down the valley and onto Stonehenge.

I have explored a series of pitched roofs at different levels . These roofs are clad in copper sheeting. Copper was thought
of as a very precious new material in the Neolithic Era.
The buildings are orientated in such a way to direct the view and flow of people and horses towards the open landscape -
encouraging exploration.

Portable Spire

Portable Spire : 9m High replica of Salisbury Cathedral Spire
Inside Salisburys stone spire, there is a complex medieval timber frame structure which allows ongoing maintenance of the stone work from the inside.
The original design had to be reworked so that the spire can stand without the outer stone cover-ing and to incorporate a means of taking it apart so it could be split into smaller units when being transported. It is made from wood sustainably sourced in Scotland.
The spire was constructed primarily for temporary installations, with the view that it could be as-sembled in many places, many times.
An A-frame was constructed to raise the spire after lots of discussions on deciding the appropriate lifting method. We wanted to celebrate the action of lifting.

Internal artificial lighting comes from hanging lights made from copper. The hanging lights give the effect of lowering the tall ceiling to make the spaces feel more intimate.
In some spaces like the kitchens or bathrooms, LED spot lights are used. These lights use very little energy, give off a lot of light and last a long time.
The south facing court takes advantage of natural sunlight throughout the say.

We were fortunate to be able to get a tour of a working Bath Stone quarry in Wiltshire. We were taken underground to see the digging and the machinery used to mine the stone.
I have used this locally sourced stone as part of my roof structure of my community hall by proposing a bespoke joint. It rests on top of the columns and joins into the timber beam supporting the roof.

The cladding is made from vertical modules of 430mm timber boards (3 x 145mm). There is a 20mm spacing between each module.
The size timber board modules including the 20mm spacings are in sync with the bricks. This is necessary to have the windows, bricks and timber board aligning in the same way on every part of the building.
The modules are attached to the primary structure with horizontal and vertical battens.
