Islington, North London The Straw Bale House is a home and office at 9/10 Stock Orchard Street, Islington, North London Designed and lived in by Sarah Wigglesworth and Jeremy Till. Sarah Wigglesworth Architects occupy the office at 10; Sarah and her partner live in the attached home at number 9. The design incorporates a number of sustainable aspects, in the hope of emulating a model of a sustainable building within an urban context. The location of the site is in a highly sought after area in Islington next to a conservation area. The brownfield site, previously a forge, faces a busy intercity railway line (close to Kings Cross) and the vibrations can be felt throughout the site which provided a difficult challenge for the architects to overcome. Although the residents, Sarah Wigglesworth and Jeremy Till are both architects, it was to be the first home either had built from scratch.

The project explores the dialogue between life and work by examining a project for a home and office on the same site. The design posited new spatial and material typologies, and researched green materials and technologies suited to the self-builder. Recycled materials (straw bales and waste crushed concrete) were innovations and their performance has been monitored. The buildings set out tom compare a lightweight structure with a structure containing a reasonable amount of thermal mass. Additional innovations include a roof meadow, rainwater recycling, a composting toilet and natural ventilation through a vent stack tower.

THE STRAW BALE HOUSE: O EXPERIENTA TRAITA

Sarah Wigglesworth and Jeremy Till bought the site in 1994. They spent the first two years collecting ideas about their dream house and waiting for the owners of the forge to relocate themselves. The designers believe the main idea of architecture is not to design something perfect but create a living experience. This concept is explained through the dining table as a symbol of creative occupation, Wigglesworth (2009, pg.62). They developed a set of four drawings called Table Manners. The series of drawings represents the unpredictable actions and behaviors during dinner. By integrating the drawing and their needs for a unified house and office, an initial plan was developed through the series. They consider the unpredictable nature of life within the plans design stages.

MODUL : The building was designed in three sections a raised office block at one end sloping down


The project also includes a large studio office, responding to the need for hybrid house/office spaces in the twenty first century city. The office fronts a railway line and is faced in sandbags for acoustic protection. The sandbags contain sand, lime and cement. By the time the bag would decay, the wall would have transformed into concrete that kept the original shape of the sandbags.


The main floor of the house is raised up on columns, with the garden and chickens occupying the undercroft. The plan of the living areas is designed to accommodate flexible living patterns, whilst the bedroom wing is conceived of as a warm haven, wrapped by a protective wall of straw. A five storey tower of books rises through the roof, providing a lookout reading room at the top. The roof of the house is planted with a meadow planted wild trawberries. The project also includes a large studio office, responding to the need for hybrid house/office spaces in the twenty first century city. The office fronts a railway line and is faced in sandbags for acoustic protection. The project has already received extensive publicity, including an hour-long Channel 4 TV documentary as part of the GRAND DESIGNS series and has been touted as the iconic house of the nineties (by The Guardian).


SUSTENABILITATE FUNCIONAL The project explores the dialogue between life and work by examining a project for a home and office on the same site.

Recycled materials (straw bales and waste crushed concrete) were innovations and their performance has been monitored.

MATERIALITATEA NECONVENTIONAL The building was designed in three sections a raised office block at one end sloping down towards the living area with a great glass wall and the bedroom wing at the bottom end. The most significant aspect of the design was the unconventional materiality. Straw bales make up the walls of the bedroom and back wall of the living area with a transparent waterproof covering to reveal the structure. The sloping roof was to grow native plants, including wild strawberries, herb-Roberts and Welsh poppies, which are allowed to seed naturally, and are irrigated by both falling and stored rainwater. A 5-storey library tower with a trainspotting room was also envisaged. The L-shaped design is arranged on site so as the office space acts as a sound barrier for minimum noise pollution from the rail to the living space. The office block is raised up by concrete gabion stilts and the wall facing the rail tracks is clad with concrete, lime and cement filled sandbags.through the series. They consider the unpredictable nature of life within the plans design stages.


SIT I MATERIALITATE: The site sits next to a railway and the building is only 3m away from the track, which means people inside the house, can feel the vibrations and hear the noise caused by trains. The house needed a sound barrier, which came in the form of concrete, lime, and cement filled sandbags which clad the wall adjacent to the rail tracks, functioning to minimize noise pollution. The weave polypropylene bags will eventually erode away under ultraviolet light leaving a fossilised effect as the cement is revealed. It is an innovative method for sound insulation and creates a unique faade at the same time. The bedrooms are far from the railway further minimising the noise when the occupants are resting. A spring system was designed above the gabion columns for the office and underneath the columns of the house. This helps to minimise the impact of the vibrations from passing trains on the occupants. A padded quilt of fiberglass and polyester lining are buttoned onto the office as sound insulation. It has strong resistance to wind, which reduces the impact of high northerly winds during winter. This is an experimental cladding system and will be replaced periodically as sustainable insulation technology progresses. This quilt faade faces the street and is designed to capture peoples interest and curiosity. Its soft quilted texture juxtaposes the hard and rough sandbags on the perpendicular wall. The window frames are constructed from reclaimed pitch-pine railway sleepers, another way in which sustainable materials are used.


The only straw bale house in London (as far as I know) is in Islington. It's at 9 Stock Orchard Street, and it's designed by Sarah Wigglesworth and Jeremy Till. "Considered the first modern building to use straw in England," says Sara Navrady, "the building combines new and old materials with new and old techniques to produce an eco-friendly urban creation... it incorporates several elements of sustainable architecture into its design: passive solar heating, solar water heating, natural ventilation, a recycled water system as well as the use of vernacular, low-energy and recycled materials, not to mention a green roof and a composting toilet. The combination of work and home eliminates the energy consumed by commuting." Sustainable architecture is also, paradoxically, cheap and temporary architecture.


MATERIALITATE NECONVENIONAL


O LOCUIN SUSTENABIL As the building was designed for the architects own use, they had the opportunity to explore the possibility of new sustainable technologies such as the straw bale faade. The idea of bales first came to the designers when they saw a straw bale building in Salisbury. There are few structures made using straw bales in the UK so they wanted to develop their own construction method. In May 1997, after submitting the planning application, they attended a straw bale building workshop in Wales to gain knowledge about bale construction. Later in October 1997, they spent a month figuring out the technique to build small-scale straw bale walls for the exhibition Faade of the future held in Birmingham in November. The straw bale walls did not comply with existing building codes to be load bearing, so a system was developed where the straw bales would fit perfectly within the timer framework, which are then secured with metal trusses and sprayed with insecticide. The process was much faster and easier than any other wall construction; several people erected the walls in less than four days. As well as being recyclable and biodegradable they have almost no embodied energy. They are cheap and provide wind, sound and thermal protection. Clear polycarbonate cladding and Galvanised steel rain screens clad the bales to reduce the fire risk of the exposed straw and protect them from the elements. Just one polycarbonate transparent section displays the bales. Like the installation they built for the Birmingham exhibition, the bales are visible from the exterior and help to draw peoples attention.

A dwelling whose walls are constructed of bales of straw, compressed and wire-tied or string-tied into large units and built up on a concrete slab as if they were oversized bricks; they are reinforced with vertical poles that pierce the bales. When thoroughly dry, the walls are usually

finished with a coat of stucco or adobe plaster to promote sanitation, fire safety, and protection against the weather; the bales provide excellent thermal insulation. Especially found in the farm regions of midwestern United States.


SUSTENABILITATEA The architects aim was to build a sustainable work/live unit and discover the possibilities of a sustainable, urban living experience. The project was innovative and experimental and natural materials have been heavily used in the construction. Straw bales had not been used in this way in the UK previously although they are cheap, easy to assemble and sustainable (as a by-product of growing wheat/barley). Straw bales have excellent thermal performance with a U-value of 0.12W/m2K. When used in construction, the thermal insulation capacity can be improved by increasing the density of bale. The technique used was inventive, if slightly unpredictable in terms of how it would develop over time. Roof windows are designed for the office building to gain natural daylight and activities mainly take place at the first floor which is supported by columns leaving the ground floor open and allowing cooler air flow into the building from the shaded areas. Small windows facing the railway and windows on the north-west facing faade provide natural cooling for the building as well as allowing daylight to enter, maximised by high ceilings and light finishes. The green roofs are designed for the living areas, helping to control rainwater flooding as well as overheating during summer. Photovoltaic cells collect solar energy for water heating. Heavily insulated walls and ceiling and the concrete floor help maintain a consistent temperature throughout the year. The building collects rainwater from the office roof in two 3000-litre tanks under the domestic wing, one supplying water for the household, the other for irrigation of the roof garden. Compost toilets integrate with the office block further reducing the water consumption.


The space heating provided by solar energy is augmented by an underfloor heating system; the solar panels used to heat water are backed up by a condensing boiler; and the composting toilet is supplemented by a conventional flush toilet in the office wing. The initial budget for the project was 400,000. The first estimate came in close to double this (!) therefore their ideas had to be rationalised and cut back to bring the estimate below half a million pounds, though it was difficult to project costs due to the unforeseeable nature of the construction.


STRUCTURA: Gabion walls are used for the office block- recycled rubble in wire mesh cages were intended to fully support the structure, acting as stilts, however they had to be reinforced using central concrete pillars within the gabions. They are more commonly used to stabilise shorelines against erosion, road building or military applications. The initial idea was modified due to the fire hazard posed by the thin wiring which would melt easily in the event of a fire and collapse the gabions now surround a reinforced concrete pillar through the centre. The rubble is in compression and the cage is in tension making the wall structurally efficient and could potentially be used to build a 6-story building. The house has two main structures; timber-framed for the bedroom wing and steel-framed for the living area. The bedroom wing was redesigned as a separate building which could be constructed first and lived in during the construction of the rest of the building, as it was the only part not waiting on the manufacture of the steel frame. The timber framework was designed according to the dimensions of the straw bales and the steel-framed structure for the living area is based on the regulations around the spring system.

LOCUIRE SUSTENABILA


THE STRAW BALE HOUSE SUCCESUL: The straw Bale house was not only a success as an illustration of sustainable design but also as an explosion of architectural wit as described by Charles Jencks (2011, pg. vii) in Around & About Stock Orchard Street. The house is a living experiment, continuously adapting from Sarah and Jeremys outset into the project and is, as Jencks coins it, an auto-building the working through an architectural concept without compromise. From the use of straw bales to insulate the bedrooms in the north wing to concrete filled sandbags that cover the faade facing the railway, acting as a line of defence, the design is seeped in innovation. Furthermore, the architects ability to adapt to the constant change throughout the build in order to meet their desired result was the key to winning the Against the Odds prize in April 2012. The joining between three different volumetric spaces, made up of three different materials is definitely a new way of thinking which showcased the architects and to-be-residents risky stylistic approaches that, Against the Odds, flows seamlessly.


THE STRAW BALE HOUSE SUCCESUL: The house is highly renowned in England for its variety of materials in trying to achieve the high standard in ecologically friendly living. Underneath the house there are two tanks that each have the capacity to take 3000litres of rainwater. These have supplied the house with the majority of its water, one tank being used for the water in the ecological toilets within the building, whilst the other tank provides enough water to water the strawberries, flowers and plants that lie on the roof as well as the garden. Another way in which the architects have found a way to cut water consumption is through the use of a composting toilet system that is continuously ventilated producing an odourless fertiliser. This means that while the house still uses water for drinking, cooking and showering its water consumption is dramatically reduced, producing up to 6000 litres through rain collection. A large part of the sustainability of the design is through the temperature control, which is entirely natural and inexpensive (Floor Nature, Sarah Wigglesworth and Jeremy Till, The House of Straw, 2001). This natural and inexpensive method is exhibited by the Insulation of the house; the sandbags are inexpensive, combined with the natural deployment of the straw bales that engulf the lower part of the building. The house is warmed by a simple wood stove during the winter as well as by body heat, whilst in the summer it is cooled by the evaporation from the water on the roof garden keeping the whole house at a consistent temperature. This reduces the need for central heating during the winter while cooling the house in the summer. This has the added benefit of reducing the need to open windows further cutting out the noise from the railway.


THE STRAW BALE HOUSE SUCCESUL: 2004 RIBA Award: Sustainability Award 2004 RIBA Award: Regional Award 2002 Civic Trust Award 2001 FX/Blueprint Award Best Residential Building of the Year shortlisted for the Royal Fine Art Commission Building of the Year 2002. The project has become critically acclaimed in many areas of the architectural world and has won a great deal of awards ranging from the 2004 RIBA Sustainability Award to the 2001 FX/Blueprint Best Residential Project. It has become an icon in the world of sustainable development in England. Even before the project had begun construction, the Straw Bale House received much publicity due to its innovation in sustainable design and complexity in combining so many different aspects, both Architects having already given lectures about the proposed building before work had even begun. It is the value of 9 Stock Orchard Street as a research opportunity that has attracted the architecture department of Sheffield University to conduct an ongoing study of the building, and its unconventional combination of architectural elements that has earned its continued mention in the architectural press.

THE STRAW BALE HOUSE What then can be learned from this project, clearly steeped in architectural experimentation and sustainable ideals? Is it possible to transfer this design in whole or even in part to other locations or perhaps make it a model for which to design around in the future? As mentioned, the project was of a very personal nature tailored to the clients who happened also to be the chief architects; Sarah Wigglesworth and Jeremy Till dreamed the idea themselves and now inhabit their own living experiment to explore their architecture born without compromise between architect, client, developer, contractor or user and because of this they have been able to create something quite unique.


THE STRAW BALE HOUSE What then can we learn about sustainability from this project? Because Wigglesworth and Till were designing their own house they felt free to go through an iterative process of experimentation, completely fluid [and] dynamic, Gillian Horn (2009) as opposed to the likes of far more disassociated Design, Build, Finance, Operate (DBFO) procurement method used within the Private Finance Initiative (PFI) where the client is removed from center-stage to the wings, saying only what is wanted not what is to be achieved. The Straw Bale House suggests that small scale experimental development is the path to a realization of a sustainable future. The great use of sustainable building techniques and materials that Stock Orchard Street has employed has been a result of this relationship between Sarah, Jeremy and their brainchild; their home; their workplace. As Trevor Butler states; The drive [for a sustainable future] must come from the clients who, as energy costs increase and the carbon footprints of new buildings are publicized, will demand that their design teams produce buildings that (in all senses) perform better. Butler (2009, pg.189) One of the driving factors for the design was the creation of a dual-purpose building that incorporated home and office in a state of symbiosis, combining a very public function with that of a private one. As Frances Holliss (2009, pg.84) points out in reference to Stock Orchard Street such dual use buildings have existed for hundreds if not thousands of years, however there is little written about this building type. It seems that where the Industrial Revolution separated home from workplace, the information economy is bringing these two together as we are now able to work wherever there is a Wi-Fi signal. How does this relate to sustainable living? Jabareen (2006) states that reducing the need for travel is on the agenda of achieving sustainable urban form, and mixed land use has a prominent role in achieving it. Since the dawn of industrialization rigorous zoning through urban planning has left a cityscape with less diversity in local areas and more traffic, as well as reduced safety, Newman (1997).
