wetherdown lodge 
​Stage 1

The self catering wing known as Wetherdown Lodge will never win any architectural awards. Indeed this ex-naval accommodation is typical of many utilitarian buildings of the 1960s which have since been torn down and rebuilt.

However, it's fundamental to our ethos that we first try to work with resources, rather than dispose of them. We also saw the potential for creating excellent new accommodation for people visiting the Centre, enabling them to spend longer with us. We therefore took the decision to embark on a total refurbishment, and create a model of sustainability in the process.

Features include:

• Sustainable external wood. All of the external wood cladding and window frames are made from softwood from sustainably managed forests.
• A marmoleum floor. This floor lining is made from the natural materials of linseed oil, jute and chalk, and is very hard wearing.
• Photovoltaic cells. These cells collect light energy and convert it into electricity which directly feeds the Lodge. The cells are an actual part of the roof as they integrate with the roof tiles.
• A pitched roof with thermafleece insulation. The original roof was flat. By altering this to a pitched roof and then insulating it, we increase the energy efficiency and retain heat in the Lodge. The thermafleece lining is sheep's wool which is much less hazardous to lay, and also biodegradable when it needs to be discarded.
• Recycled paint. As we redecorate we are using water based eco-paints.
• Triple-glazed windows. Having three panes of glass increases the energy efficiency of the buildings and keeps heat in the hostel.

What We Have Achieved
The project has given an existing resource a new lease of life, as well as provided the Centre with an important asset. Crucially, our sustainable energy solutions have reduced energy consumption by a remarkable 80%. Much of the lodge's remaining energy needs are supplied by renewable energy.

Equally important is that this 1st stage retrofit shows what can be achieved with buildings of this type, which include schools, community centres, public buildings and housing. We have proved that it is more cost-effective, and clearly more sustainable, to improve rather than demolish.

This project has received support from the Department for Environment, Food and Rural Affairs and the European Agricultural Guidance and Guarantee Fund.

The first stage of works was retrofitted in 2005 on a very modest budget to provide 38 bed hostel-type accommodation which will be priortised for school visits, group bookings.
 
Stage 2 Retrofit 2020
​We hope that this eco retrofit build inspires others to transform their homes, offices and commercial buildings in a similar way. Stage 2 of works, known as the B&B wing, completes the transformation of this former MoD accommodation block.

​Features include:

• Ground Source Heat Pump - A renewable heating system extracts low-temperature solar energy stored in the ground using buried pipework and compresses this energy into a higher temperature.
• Mechanical Ventilation with Heat Recovery - a ventilation system that brings fresh air into a building while removing stale air and humidity. MVHR systems are often used in airtight homes and other buildings that require better air quality and energy efficiency.
• Photovoltaic panels – convert sunlight into electricity.
• A new pitched and insulated roof
• Triple glazing
• Natural and local materials
• External insulation and cladding (Western Red Cedar – locally sourced)
• Low or no VOC paints
• Non toxic flooring
• Energy efficient lighting
• Upcycled furnishings
