Bullock’s Ley was converted from working barns using natural materials and a combination of traditional and modern technologies, including a state-of-the-art heating system. Visitors to Bullock’s Ley often comment on how comfortable the building is inside, regardless of the conditions outside.
The under floor heating, coupled with continuous mechanical ventilation, a high-tech air supply system and a well sealed building ensure that your stay will be a comfortable one.
A Ground Sourced Heat Pump was selected as the method of heating. This involved the installation of a kilometre of heat collecting pipework buried outside and a further two kilometres inside, distributing this heat under the floor.
This system is four times more efficient in its production of heat than the best gas or oil powered system. It is fully automatic and thanks to its monitoring system, which takes external conditions into account, produces only enough heat for the interior to reach the desired temperature.
A Continuous Mechanical Extraction System was installed, ensuring that the minimum amount of air necessary to effectively ventilate the building is admitted. Fans running constantly at low level draw a set amount of air through adjustable vents in the ‘wet’ rooms. When higher moisture levels are detected (i.e., when bathrooms are in use) the fans automatically boost until levels return to normal. This system operates in conjunction with the Supply Air Windows mentioned below.
Supply Air Windows were fitted throughout the building. These were a new innovation in the UK at the time the conversion was taking place and are still relatively unknown. Air is drawn into the building by the ventilation system; it flows between the internal and external panes of the windows, gaining heat in the process as a result of the greenhouse effect. In addition to this gain, any heat escaping through the internal pane is caught up in the air flowing into the house and so returned. The overall efficiency is comparable to or better than triple glazing.
Draught Proofing is at least as important as insulation and perhaps more so. Great care was taken to seal the building and any small gaps remaining after installation of insulation were filled with silicone sealant before internal finishes were applied. Any penetration of external walls, such as by roof timbers, were carefully inspected and sealed as necessary. All windows and doors were supplied with integral draught seals.
Clay Lump construction was used in the majority of the internal walls. This added 40 tonnes of unfired thermal mass to the building enabling both heat and moisture to be absorbed and released, effectively regulating the internal climate.
Insulation was paid particular attention. Warm roof construction was adhered to throughout. This involved three layers of insulation to the roof: Celotex sheets to the underside of the rafters, blown cellulose (recycled newsprint) between them and mineral wool batts on top.
The first floor walls are of timber construction and these received similar treatment.
A skin of hemp lime blocks was applied to the inside face of the original solid brick external walls. This resulted not only in greatly improved U-value but also in a completely breathable construction which enables moisture to dissipate naturally. Use of lime render to internal surfaces assists this process.
The house is beautiful to behold, with its warm colors and lovely views of open fields and trees. The hosts were warm and welcoming, and the food was some of the best I have had in a retreat center. Read more »
