New builds are designed with sustainability in mind, but period houses, while beautiful, often lack eco credentials.
This guide will show you how to turn a period house into an eco house. We will examine when listed building consent is needed and explore the top building materials and techniques used in sustainable housing.
First of all, check if your period property is listed, using this list from Historic England. Obviously, if you are outside of England, you need to check the list of the appropriate heritage organisation for your part of the world.
If your building is listed, then you will require listed building consent for any renovation work to the interior. In addition to listed building consent, planning permission will be needed for external work. Listed building status also applies to the garden, while trees may have a tree protection order (TPO) on them.
Check your home’s listing to find out exactly what features are covered. Do not carry out works without listed building consent because you can be prosecuted.
Make the Most of What You’ve Got
Etons of Bath points out that by renovating a period home, you are effectively recycling a building. Retaining period features cuts down on waste. They recommend reinstalling wooden shutters for warmth and draught exclusion. These and other period features can be sourced at reclamation yards.
Always use, where possible, locally sourced building materials, as would have been used in the period.
Keep It Natural
Etons of Bath suggests using natural materials such as haired or hemp plaster for insulation. Stone, lime render and plaster, timber, and wool are all sustainable, natural and in keeping with period properties. Lime wash eliminates the need for a damp course by letting walls breathe and is also an excellent source of fireproofing.
Historic England states that ‘timber windows dating from the First World War generally used Baltic pine…use matching timber that is low in sapwood so that it lasts as long as possible.’ In every instance, replace rotting timbers with fresh wood that matches, while trying to keep as much of the original, non-rotted timber as possible.
As a final step for natural eco-living, overhaul the garden. Vegetable patches were a key part of many historic garden designs, see if your property still has one, or work out where one could be developed. This will be both in keeping with the period, often when it was essential to live off the land, and also fit in with today’s standards of eco-living.
When To Modernise
The Listed Property Owners Club, Scotland, says
"If you are looking to make thermal improvements without the need for listed building consent, options include; draught-proofing, improving loft insulation and upgrading to a more efficient boiler (so long as it does not involve altering the building). Double-glazing windows and adding insulation to walls and floors can be a little more challenging and will almost certainly require listed building consent."
Historic England prefers homeowners to install secondary glazing rather than double glazing. There should not be a problem with changing the boiler, providing any unsightly pipework is hidden and there is minimal work needed to the fabric of the building.
LED light bulbs should be fitted unless the light fitting is part of the original features and/or is listed.
We hope this guide on turning your period house into an eco house has been helpful. Wherever possible, retain original features and enhance, rather than replace.
