About Us

We are an established family-run construction company committed to providing great buildings to specification, on time and on budget. As brothers we have over 40 years combined experience having began our building careers working for our father and uncle prior to establishing Derwen Llyn Construction Ltd in 2015.

We are able to offer a complete construction service centred around our highly skilled and experienced workforce who blend old-fashioned craftsmanship with modern building technology and materials.

Our reputation for quality workmanship, reliability and attention to detail has helped us gain numerous client referrals and recently we were awarded the prestigious Building Excellence Award by LABC Wales for Best New Build Dwelling.
