Glamorgan, Denbighshire, Flintshire and Breconshire...just a few of the 13 traditional Welsh counties, before local government reorganisation changed things in the 1970s.

The old names will be given a new lease of life on Wednesday nights as Y Tŷ Cymreig (The Welsh House) travels from county to county to visit interesting houses of architectural and historic significance.

In previous series, presenter Aled Samuel and architectural historian Greg Stevenson and his dog Minti looked at houses classed by style and period to try to establish if there was such a thing as a typical 'Welsh house'.

But this time, in the series produced by Fflic, one of the Boomerang group of companies, each programme profiles a variety of houses in a particular county, ranging from 15th Century Tudor homes to industrial domestic developments in the 20th century.

“I think S4C viewers will enjoy seeing collections of homes in each county,” says 51 year old presenter Aled Samuel who lives in Llandeilo. “Many people are familiar with the names of the old counties and those names bring back memories. I'm always reminded of the Urdd Eisteddfod Pavilion where the names of the old counties would be listed as they battled it out against each other.”

Cardiganshire, Breconshire, Carmarthenshire, Caernarfonshire, Denbighshire and Flintshire will appear in this series of Y Tŷ Cymreig , with the other seven shown next time.

Aled explains, “At the end of the last series we came to the conclusion that there was no such thing as the 'Welsh house' and that houses in Wales tend to be influenced by fashions and styles from over the border in England and further afield in Europe.

“But what became obvious was that there are regional differences and it seemed a natural progression to study houses county by county. There are definite similarities within a county due to the nature of the landscape, the local stone, agriculture and industry.”

The first programme concentrates on four houses in Cardigan, Greg Stevenson's home county. Among the houses visited are Plas y Wern manor, where Henry Tudor is thought to have stayed before the battle of Bosworth, an amazing Victorian home in Aberystwyth and an ancient farmhouse near Strata Florida.

But in Aled's opinion, which county has most to offer? “I'm looking forward to visiting Glamorgan, where I was born, but each county has its own qualities to be honest. We've found interesting houses in the most unlikely places – and these buildings deserve programmes in their own right.”
