What visitors are saying

"Every house is different - mine seems to have so many difficulties! It was good to see a house of similar age. Thank you so much for showing me around."

"Really useful to meet a family living in such an improved educational property and see it in practice."

"Great - the owner is really knowledgeable and very good at sharing his knowledge."

"Good to see how partial internal/external insulation works. Reinforced our plans to do the same!"

"Great to be able to talk to someone who has done the work rather than reading things or talking to builders. Already planning on doing some insulation in my home."

"Interesting to find an older home creatively insulated."

"Very interested in the use of Celotex insulation - planning to use the same on our beehive for when the cold comes."

"The hosts were friendly and were able to describe well the changes made and the issues they overcame on the way."

"Most interesting to see a 'normal family home' which has so many eco-features without altering the nature of how it looks / functions."

"I am really impressed with lovely house. I am also impressed with the insulation measures, as I plan to do something similar in my next house."

Personal story:

We moved into this house in 2001 and improved it in two stages – the initial stage was needed to replace a worn out boiler, single glazed windows that were in poor repair and insulate the loft. Arthur Williams is a lecturer in energy topics to engineering students; Regina Dengler a Complementary Therapist, so we had an awareness not only of energy saving technologies but also the benefits of using natural materials for a healthy home. The second stage of the improvements included the external wall insulation and the installation of the PV, with the aim of improving the comfort of the house and saving money in the long term.


In the first place the improvements were made to make the house more comfortable to live in and save on energy costs. Before the second stage of improvements we had started to monitor our energy use and had become aware of the poor energy rating of the house, which is typical of most houses built before 1920.

Property background:

The property is a three-bedroom house built in 1902. It is detached, but the floor area is similar to many semi-detached properties (100 sq.m). It is mainly brick construction, with 9 inch (22 cm) solid walls. It has a slated roof, but the original slates have been replaced by fibre cement slates. It has some decorative features typical for houses of this age – Bullwell Stone plinth below the window level at the front of the house; leaded lights in the front door and window alongside the front door. The front of the house and the remainder of the ground floor exterior was rendered when we moved in. The addition of the external insulation has therefore made limited difference to the appearance of the property.

Key changes made:

• Wood framed double glazing with low-E glass
• All windows either replaced or fitted with draught proofing
• External insulation – 60 mm Phenolic board rendered over
• 50mm internal wall insulation
• 220 mm with “warmcell” recycled paper loft insulation
• 20mm floor insulation to kitchen/dining room
• Gas-fired Condensing combi boiler fitted and TRVs on all room radiators
• 3.85 kW photovoltaic system
• Woodstove fitted in living room
• Low energy lighting throughout
• Low energy appliances throughout
• Water saving devices include; low/full flush devices on toilets

Measures installed in detail:

  • Wood framed double glazing,  low-E glass
  • All windows replaced or draught proofed
  • External wall insulation
  • Internal wall insulation
  • Loft insulation (recycled paper)
  • Floor insulation to kitchen/dining room
  • Floor insulation to living room
  • Gas Condensing Combi Boiler and TRVs
  • 3.85 kW solar PV system
  • Woodstove in living room
  • Low energy lighting
  • Low energy appliances
  • Water saving devices (low/full flush devices on toilets)
Benefits of work carried out:

The refurbishment has made the house easier to keep warm in winter and has improved the indoor environment. Before the external insulation was applied, patches of mould appeared at points against the cold external walls where there was limited ventilation. Overall, the process has made us, and our children, more aware of energy use and ways to reduce our reliance on conventional fuel sources.

Favourite feature:

In winter – the wood burning stove; in summer the solar PV electricity – with careful planning we hardly need incoming electricity during the daytime.
