Rooflights and skylights fitted in Penclawdd

Penclawdd is one of the larger villages on the Gower peninsula, and its Welsh name is Pen-clawdd. It is most famous for its cockle industry, which goes back to Roman times, and the estuary on its doorstep is thriving with wildlife.

Heavy industry came too. The village was renowned for coal mining and for its extensive tinplate, copper and brass works, run by the Cheadle Copper Company. Around 1800, John Vivian of Truro in Cornwall became managing partner in the copper works at Penclawdd and Loughor, then owned by the Cheadle Brasswire Company of Staffordshire. The Penclawdd Canal joined the Burry River at Aberkeddy, and a busy railway station once served the place; the original platform still stands today.

Life had its own scale. At one time the village had a forge, twenty grocers, three butchers, three drapers, four fish and chip shops, eleven pubs and a cinema, along with three chapels and a church. Those three chapels and the church are still standing. The derelict Hermon Chapel, built in 1807, was once used to help ships find their way up the estuary.

The run out from Swansea is 9.17 miles heading west, short enough to sit well within our patch. Crofty and Three Crosses are neighbours, and we fit in both.

Look up from the lanes today and the roofs tell their own story of that mix. A village that grew in stages can have roofs of different ages and shapes, and the right rooflight for each depends on the slope, the room under it and the weather it faces. That is general to villages that grew this way. Your own house may be an exception, and a survey is how we find out.

City and County of Swansea Council handles planning for Penclawdd. On the Welsh Government's map of conservation areas, one is named Penclawdd, and it covers the point we use for the middle of the village. In Wales, putting a rooflight into the roof slope of a house inside a conservation area needs planning permission. The map does not follow property lines, so the exact address decides, and the council's conservation areas page has the detail if you want to look up your own street.

The Gower AONB is the other designation to know. Boundary data puts the middle of Penclawdd outside it, but a rooflight on a house inside the AONB needs planning permission too, so an address near the edge of the village is worth checking on the council's AONB page.

Elsewhere, whether a house can add a rooflight without an application depends on the conditions in the planning guide. For flats and maisonettes there are no householder permitted development rights at all. Elsewhere a council can take rights away through an Article 4 direction, or by a condition tied to a house's first permission.

A listed house needs listed building consent for work that would affect its character. Cadw says that replacing traditional windows with uPVC on a listed building will not normally be acceptable, and its consent guidance explains what the application covers.

Building Regulations follow their own track, apart from planning. A new opening will generally need approval from a building control body, and a like-for-like replacement is still building work. We take care of the notification when it applies, going through local authority building control or a registered building control approver.

Anyone who wants certainty before work begins can ask Swansea's planners, and the paper called a Lawful Development Certificate records their reply in writing. It is a useful paper to hold when you sell, and it saves guessing about a boundary line.

Windows set in a pitched slope are the everyday job. A roof window lies in line with the roof, and in Wales a new or replacement one should reach 1.4 W/m²K or Window Energy Rating Band B. If the room is a bedroom or bathroom you want the sash to open. See electric opening rooflights for the motor and sensor options, and VELUX windows for the brand's range.

Over a flat extension you pick between a low flat rooflight and a taller lantern. Manufacturers typically want a fall so that water runs off a flat rooflight. VELUX says its flat glass rooflights come in double or triple glazing. Where the extension is new, a lantern on it is a matter for the council, and on an existing flat roof it is normally a planning matter, given how high it stands. For the flat rooflight, the Welsh figure is 2.2 W/m²K.

Older homes ask for more care. A conservation rooflight is built with older roofs in mind, and inside the Penclawdd conservation area it is the type to raise with the council. The VELUX conservation roof window has a laminated inner pane and a toughened outer pane. Approved Document L even provides a fallback for a replacement roof window on a home of architectural or historic interest that cannot reach 1.4: a centre-pane value of 1.2 W/m²K, or low-e secondary glazing. Rooflights get no such fallback.

Inside a house of any age, a landing with no outside wall can be darker than the rest. A sun tunnel reaches it where a window cannot, using a dome that sheds rain easily and a tube that needs no structure beyond the loft space above. It suits the passage at the top of the stairs, the bathroom with no outside wall and the hall that gets little sun.

A bathroom or kitchen window carries one more point. Swapping a window should leave the house breathing no more poorly than it did, and trickle vents are part of that picture. A room that depends on natural ventilation needs somewhere for damp air to go, and in a steamy room that matters for the glass as much as for the plaster. We look at it during the survey.

If an old unit has failed, swapping it is a job we do. Misted rooflights explains the signs.

Surveys are free and carried out before any figure is given. After the survey comes a fixed written quote, and our workmanship is guaranteed for ten years, with the guarantee set down on paper. Ring 01792 929062 or book through the form.
