Percy Williams Development
Welcome to Percy Williams and Sons Ltd,  builders of New Homes in Cornwall.

Percy Williams and Sons has been trading for three generations under guiding principles of quality and value. Rather than working on a large scale, we at Percy Williams have concentrated on finding and developing small to medium-sized sites to create high quality new homes with character and integrity. In other words, buildings that are great to live in, part of the local Cornish community, and yet also, at the cutting edge of technology and design.


Simon Williams and BuildersSavings on house purchase by buying direct.

We build a wide range of property for all budgets, from first-time buyer flats to larger family homes. As we don’t build on a large scale, we are able to deal with you directly. Selling our homes direct offers significant savings, as well as maintaining a close relationship between us, the builders of your new home and you, the purchasers. For more information about our houses please visit houses for sale in Cornwall page.

We have pushed the boundaries of green building technologies at Fairglen, Hayle, where the running costs are a fraction of those in conventional homes. Here we have demonstrated our commitment to lessening our impact on the environment based on a high standard of modern architecture alongside an exceptionally low carbon footprint.
We are passionate about our buildings and about creating the best new homes in Cornwall, and hope you will be inspired by them as well.

Fairglen Eco Community is a groundbreaking development in Cornwall.  This video produced by the Carbon Trust goes behind the scenes to talk to the developer and architect and shows the ethos behind the development.  Showcasing these beautiful homes it describes the techniques used that have enabled the houses to have approximately 70% less carbon emissions than a normal building regulation house.

See first hand how the heat pumps, rain water harvesting and solar panels help to keep the home at a constant temperature and supply hot water on a shoestring. The large windows give plenty of natural light and add to warmth and open plan style of the house.

One resident describes enjoying substantially reduced power bills - in the last year his total cost for heating,  power and cooking came to under £500.

2011 Outlook - Cornish Homes for Sale

As we approach the end of the year 2010, we can look back and see that it has proved to be very much a ‘mixed’ year in sales. Stamp duty changes affected the market with the £175,000 threshold helping sales earlier, although the reversion to £125,000 has seen some house prices decline throughout the latter part of the year. There has been a general increase in the number of properties available for sale from August to October, which has led to pressure and competition in pricing.
