The area of the Decontamination Centre was made into a wild flower Peace Garden after its demolition. The Peace Garden features in the The Baildon Peace Walk - a walk to see the three war memorials that was produced in conjunction with Baildon Community Link. A PDF version of this is available here.
You can read more about the wartime history of the decontamination centre in the Wartime Remembered booklet.
The original building was a simple single storey linear building with airlocks at both ends and a short water tower. Although the centre was not a listed building, it was considered to be of historic interest by West Yorkshire Archaeology Advisory Service because of its original function. As a result a condition of planning consent for the new community centre was that a record of the building, and investigation of its original function, was undertaken before its demolition. Baildon Community Link commissioned Garry Miller, an architectural historian, to produce the report and they have kindly provided a copy that can be read here, alternatively click on the cover image below.
The report mentions the Wartime_Remembered publication.
The map detail on page 17 of the report shows the extent of the Sandals Pond in 1934.
After WWII the building was used as the kitchens and canteen for Sandals School, Cliffe Ave. until replaced by a portable building in the school grounds.<Details and dates needed>
Note that the main school building on Cliffe Avenue was converted to apartments after the school re-organisation of 2000 and the school on West Lane (previously Belmont Middle School) changed its name to Sandal Primary School. Houses were built in what had been the playground of the school.

This Community Centre is thought to be the first carbon neutral community centre built in England.
Baildon's Brand-New Carbon Neutral Community Centre - the Grand Opening
On Saturday 7th May, Baildon Community Link's brand-new building was officially opened by Councillor Andrew Mallinson. The afternoon began with a speech from Baildon Community Link's Chair, Renee Lancaster MBE. Councillor Mallinson then said a few words before cutting the ribbon, and Treasurer Tom Gurney also spoke to those assembled outside the building. Everyone who had gathered to see the Grand Opening then moved inside the building for refreshments (and to escape the rain which had begun to fall). A local choir, Noteworthy Women, performed a varied selection of songs in the Main Hall. Artist Yvonne Parr, who leads a Painting group at the Link, held painting sessions for visitors, and Diane West (the leader of the Rag Rugging craft group that meets at Baildon Community Link) was present to see the unveiling of a piece she and her group had produced. There was also a Friends of the Earth stall inside the building. Two slideshows featuring photographs that tracked the progress of the building works were played on a loop in the Lounge and the Meeting Room. There is a report of the Grand Opening in the Telegraph and Argus. Centre Manager and Community Development Worker Lucy Maddison said: “The community have been incredible and everybody is thrilled with the new centre.”
The following is extracted from the EcoArc website and gives details of the 2011 work. Note that the activities and groups listed are from 2011.
New Eco Build Baildon Link Community Centre
Baildon Community Link (The Link) is a non-profit making community company limited by guarantee. The Link strengthens community life, increasing confidence, capacity, cohesion and community spirit. It works at a grass roots level, developing community responses to personal and social needs. It provides a community centre managed and led by local people and supports the provision of centre based and outreach services that meet community need. The Link works across Baildon, but focuses on individuals and families experiencing isolation and financial hardship and pockets of deprivation, especially on the Ferniehurst estate. It actively values and engages local people, drawing on their expertise and giving them a voice to shape and influence services.
Before the eco new building ‘The Link’ was based in a World War 2 decontamination centre, built as a temporary structure and leased at a peppercorn rent from Bradford Metropolitan District Council. Over the years, a small army of volunteers have patched, decorated and improved the building, working to overcome its flat roof, lack of insulation and poor layout, to provide a welcoming and functional space.
The constructed new eco build centre enabled the improvement of local community facilities, widen access to activities and services, improve health and well-being, improve local partnership working, reduce isolation and loneliness and be a model of an energy efficient and sustainable community building. The client key drivers are as below:
- Develop the existing activities and services which include elderly day care, community parties, community cafÃ©, community cohesion activities, intergenerational work, youth work, community education, parent and toddlers and affordable room hire.
- Introduce new activities and services in partnership with other organisations which will include community arts activities, a befriending project, exercise and well-being classes, a food co-op and affordable room hire for groups who lost accommodation when the former school at Ferniehurst was demolished.
- Contribute towards redressing the number of closures of local facilities and schools that had previously been used as resource centres.
- Accommodate groups who are unable to access the current community centre building because of a lack of space.
- By design, provide purpose built and multi-functional community space including adequate storage space and outdoor recreational space.
- To be more sustainable because of the energy saving measures designed into its structure, including photo-voltaic cells on the roof, ground source heat pump and, income generation through affordable room hire, and increased local involvement at all levels across the organisation.
- Contribute towards local and national plans and strategies by partnership working, including providing a suitable venue for other agencies to provide local services, including housing, police, councillors’ surgeries and neighbourhood forums.
- Contribute towards local capacity building by increasing local volunteering opportunities.
- To be located at Ferniehurst, a pocket of local deprivation, thus contributing significantly to address issues of local isolation faced by local people without transportation who face real challenges accessing alternative services, and contributing to the social life and the community spirit of the area.

Cold bridging is avoided through careful detailing around all reveals. Incidental air infiltration will be kept to a minimum through air tight construction that will provide a target air change rate of 0.75 per hour under 50 Pascal air pressure test in accord with the AECB Gold Standard.
Bio-Diverse Sedum Roof
Proprietary lightweight green roof systems were introduced into the UK over 20 years ago. Within the last five years, real intensification has occurred as architects and clients have realised that green roofs will benefit our changing environment through their ability to negate the increasing effects of CO2 emissions, reduce global warming, curtail localised flash flooding and replace habitats for wildlife. A green bio-diverse roof was installed on the community centre. The key benefits of a bio diverse roof system in this situation include: Environmental Masking: The green roof offers the design potential for the centre to blend into its surrounding landscape and at the same time replaces the permeable land otherwise lost to the construction. Practical Use of Waste Materials: Many recycled materials are used which have minimal impact on the environment. The waterproofing membrane, drainage layers and growing mediums i.e porous brick, are readily used. It is also possible to re-use the secondary aggregate from the original site as the growing medium; this further lessens the impact on the environment by reducing the need for waste disposal to landfill and the associated transportation. Wherever possible, salvaged, reclaimed, recycled or recyclable materials will be used within the Green Roof System. Improved Air Quality: A natural process of plants is photosynthesis whereby they use the energy from sunlight to convert water and carbon dioxide into sugars and oxygen. The chemical equation of photosynthesis shows that six molecules of CO2 and six molecules of H2O are converted into one molecule of sugar and six molecules of O2. The more vegetation that is planted on a site the better the air quality. The vegetation will attract airborne pollutants and dust particles, removing them from the surrounding air. Storm Water Management: Green roofs retain rainwater by storing it in the plants and substrate, which then evaporates back into the atmosphere. By slowing down and reducing the levels of rainwater entering the drainage system, less strain is put on what are normally inadequate public sewage systems thus helping to mitigate flooding. A green roof will retain 40 – 90% of average rainfall, depending on the time of year. Thermal Performance: A green roof will provide greater thermal performance for the roof. Ecological Benefits Creating a Natural Habitat: Both plants and small wildlife are encouraged to remain in the area as a habitat is recreated that would otherwise be lost to the footprint of the construction. Aids Biodiversity: The provision of a living habitat specifically designed to target a species of plant or wildlife. Natural colonisation and cross-fertilisation of plants allows for a truly natural habitat to form, though a helping hand can be given by sowing a specific seed mix. The roof is generally self-sustaining and so requires minimal maintenance. Local sedums can be cultivated in the garden and incorporated in to green roof-growing medium.
Passive Solar Design
The large percentage of the high performance solar glazing, high level clearstory glazing and the entrance passive solar sunspace is orientated southwards to provide passive solar gain to the main spaces. Window openings to predominantly service zones to the north elevation in comparison are reduced to a minimum to reduce thermal loss. Tree foliage and external solar shading will prevent excessive heat gains in summer and internal insulated blinds will reduce heat loss to a minimum to windows at night time.
Site Generated Zero CO2 Renewable Energy
Zero CO2 Photovoltaics, Ground Source Heat Pump & Intelligent Thermal Hot Water Store
Carbon neutral renewable energy are provided to the community centre with integrated solar polycrystalline photovoltaic panels mounted on the south-facing roof to convert sunlight in to domestic electricity. The south-facing roof provides optimum solar orientation with a projected peak output of renewable energy. The panels are formed from matt grey frames with black /blue infill panels and would be integrated in to the sedum roof. A ground source heat pump (GSHP) extracts latent heat deep within the ground to form hot water for under floor space heating. The GSHP is linked to an intelligent stratifying vented thermal hot water store with a series of heat exchangers. The configuration of the intelligent store ensures mains cold water is instantaneously heated on demand via heat exchangers making it mains pressure hot water. The actual water in the hot water store does not come out of the taps, it only gets as far as the heat exchanger off loads its heat to the fresh water supply before returning to the main store. GSHP thermal water heats another heat exchanger, which heats stored water that then flows by convection into the store at various points depending on the temperature it has reached. The advantage of this heat exchanger system is that it can deliver heat on demand.
Wind Assisted Passive Stack Heat Exchange Ventilation
Mechanical ventilation been avoided in favor of a healthy passive wind assisted heat exchange ventilation system to the main hall. This naturally draws air through ducts from internal spaces and vents stale moist air through heat exchanger roof cowling vents without using electricity to power unnecessary fans.
Once a building is super-insulated and airtight the biggest source of heat loss is the ventilation required to maintain good air quality. To reduce heat loss it is necessary to pass supply and extract air through a heat exchanger so the out going warm stale air transfers its heat into the incoming cool fresh air. Traditionally this has been achieved using electric fans via a mechanical heat recovery system (MHRV) that is energy consuming and produces CO2 which is clearly not ideal for a carbon neutral building. Electricity is responsible for three and a half times the amount of carbon dioxide per kilowatt hour as heat is and is four times the price, so for a heat exchange ventilation system using an electric fan to be useful it must save at least three and a half times the amount of heat kWh as the electricity kWh the electric fan uses which, is physically impossible. In a carbon neutral building relying on site generated renewable electric energy it is important to reduce demand to the minimum and avoid all non-essential electric fan loads. In reality the cost of providing PV’s to run a mechanical electrical fan heat recovery system can be prohibitive and space absorbing. To avoid these issues and provide a non-electric sustainable passive ventilation system to replace an electric hungry fan system, 4 No a roof mounted cowls that use wind pressure and stack effect pressure to force fresh air in to the building and suck stale air out of the building via a non mechanical heat exchanger were installed.
Low Energy Appliances
All appliances were be carefully considered to eliminate unnecessary electrical demand and to optimize the efficiency of the required essential items, cooker, fridge, lighting etc. All selected components are category A** rated for maximum efficiency and minimal electrical draw when in use. Excess electricity produced from the proposed on site renewables systems, which cannot be directly used in the building, are dumped into the hot water cylinder & excess renewable electricity is exported to the national grid.
Water Saving Devices.
All domestic community centre water outlets have been selected to be as water efficient as feasible with aerated sink / basin taps, and flow restrictors fitted to external taps or hosepipes. The community centre makes use of Ifo Cera dual flush WC’s which are at present the most water efficient flush toilets available in the UK with a minimum flush of 2 litres. This may be compared with a 9-litre flush, which is commonly found in standard UK WC’s. Given that flushing the toilet accounts for over 40% of our average water use the low flush Ifo Cera WC’s can reduce consumption per toilet from 65,700 litres per year to 20,440 litres per year. Ideally we would include for a Rainharvesting recycling system but the bio diverse sedum roof substrate is not suitable for this purpose.
Cradle to grave embodied energy costs are difficult to determine, but energy intensive traditional concrete and fired brick masonry buildings rely on excavating finite natural resources from the earth which cannot be replaced and also use large amounts of kiln energy to make them strong and stable. The concrete blocks specified for the foundations and masonry walls are 7kN dense Masterblock Enviro blocks made with 100 % recycled aggregate. The roof timber frame are from a renewable resource and sourced carefully from a FSC approved sustainably managed supply. The equivalent number of trees used to make the timber frame structures will be planted on local sites with in the district to ensure that overall there is a net environmental resource gain. Roof insulation id from cellulose recycled newspaper.
Waxed timber floors, natural linoleum flooring, organic non-volatile solvent paints and stains to walls, avoidance of formaldehyde and equivalents combined with natural materials and a natural wind assisted cowl ventilation system will lead to a healthy internal air quality.
