The Joinery by Shotaro Oshima

The Joinery We consider post-war housing blocks in London essential part of the urban landscape, due to its contrasting form/language compared to other ‘period’ architecture that remain in the city. The juxtaposition and the depth of layers that exist defines the authenticity of London, and our proposal seeks to re-familiarise and enhance the importance of such architectural typology within the environment we inhabit in by introducing a dynamic timber structure extension that emerge from an existing Council Block, Telfer House. As part of UK’s strategic planning, densities are added to the suburbs of London, making the city’s boundary expand and pushing affordable living further outwards from the urban core. However, with inner London also sought as potential areas to improve, due to its relative low density compared to its recent past, there is still room for great opportunities to respond to the existing urban landscape which in some places appear fractured, fragmented and under-utilised. The post-war council estates are attractive from re-development point of view as the sites are not privately owned, but many of the blocks are endangered to become victims of the ‘scrap and build’ mentality that London has been implementing for providing new housing quickly. It is a common sight now to witness these architecture being demolished to be replaced by another set of cheap, quick-fix solutions where many of them are simple extrusions of space zoning exercise cladded in economical cladding material. Our proposal seeks to advocate a counter-strategy to this situation to enable us review London from another perspective, and to introduce a ‘progressive-minded’ alternative idea (which the principles could be implemented elsewhere) that values the evolving unique picture and history of this great city. Applying the principles of Japanese cantilever joinery and maximising the flexibility that the Kerto elements offer, we developed a structural strategy that enables dynamic three-dimensional extension that grows out of the load-bearing elements of the existing linear volume of Telfer House. The building extends outwards beyond the site in places, utilising the benefit of being part of a macro-site that is of King Square Estate. The ‘streets in the sky’ concept advocated by the Smithsons are reinterpreted here with a timber walkway that forms a bridge between the new development and the centrally located King Square Gardens, allowing the visually disconnected site become integral part of the local community. The architecture questions the basic principles of gentrified redevelopment that can be seen in London now. Challenging the developer-led-notion that a simple extrusion of the footprint of each site is the most time/cost/space efficient way of improving the urban density. The proposal intends to deal with the values shared by such schemes but also carefully considers the essence of quality of life and community building, elements that we feel are becoming diluted due to the perceived severe nature of the housing crisis. We believe that the use of pre-fabricated/engineered wooden structure is a key contributor that enables such concept be realised. Outward vs. Inward Movement Current: London core expanding outwards, filling up suburban brownfields. Affordable living in inner core London is becoming rare

Visual focal point The sculptural form of the proposed extension and its presence generated by the contrasting architectural language to surrounding buildings will enable Telfer House become one of the focal points of King Square Estate. The architecture will be visible from many points in and around the estate and will raise awareness to a wider context of the meaning of this scheme.

Post War Council Estates Particular attention was made to the fact that London Councils typically own 25-30% land in their respective Boroughs for Islington and Southwark, the record shows 40% or more. Using a medium density post war housing estate site that is situated at the heart of central London as a testbed for a new urban solution, we propose a concept that responds to many of the key urban issues the city is facing as well as bringing life and renewed presence to existing architectural features within the chosen area. King Square Estate King Square Estate is a typical post-war development that emerged in the 1950-60s, situated in south of Islington Borough. The estate is characterised by medium to high rise housing, with a central open space (Kings Square Gardens) acting as a focal point. The chosen site, Telfer House, sits on Lever Street which forms the southern boundary of the estate. The existing building is a two storey high linear volume that is sandwiched by six storey high buildings either side – the fractured townscape created by the inconsistent scale and breaking up of cohesive rhythm offers an opportunity for an infill intervention.

This approach seeks to evoke chain reaction and progressive movement to the rest of the city.

Re-familiarising ‘Estate’ feel The Joinery extension will not be contained within the boundary of Telfer House micro-site.

Instead, the building will reach out beyond and towards various points of King Square Estate. This gesture will enhance the sense of ‘estate’ feel that the current Telfer House is lacking, generated by the low-rise appearance (lacking visual cohesion).

The closer integration of Telfer House to the estate will enhance the importance and identity of the exsiting modernist structure and consolidate a sense of ‘community building’

The Joinery - Level 05: 3xbedsit, 3x2bed, 3x3bed Floor Plans 1:500 Upon review of the King Square Estate, it has become apparent that there currently is an existing redevelopment proposal for this particular site. It consists of total demolition of the existing Telfer House, and providing a new build providing 38 flats ranging from 1 bed to 3 beds. As a counter-scheme to this, The Joinery proposal provides exactly the same density, but with different number of flats. A notable factor is that the number of provision for the existing Telfer House (10 bedsits and 6 3beds) are reprovided in the new extension, allowing existing residents to have a choice of moving into the new dwelling units. The sequencing of refurbishing the Telfer House units are also allowed in, so consideration to the community and disruption fears are rigorously looked at.

Phase 03 – 12 weeks - Main building works – new ‘extension’ assembled and erected using modular material and building elements produced off-site - Handover of 94 new units (main extension) and bridge

Typical redevelopment in London tends to follow an option of simply extruding a zoning diagram fitted within site boundary, which is a signiture of ‘scrap and build’ mentality and result in diluting sense of place

The proposal advocates a sculptural approach so the existing structure is extended upwards but three-dimensionally, as opposed to simple extrusion. This creates a more memorable form that will engage with the urban landscape in different ways.

Phasing/Sequencing Diagram The current proposal that exists which consist of demolition of Telfer House and rebuilding a new build is expected to take approx. 50 weeks construction with relocation (disruption) to the existing residents. The proposed scheme here will free up 18 weeks, which can be utilised in the design stage
