Sarn Park is pretty hard to access when heading westbound, located opposite the McArthur Glen Designer Outlets in Bridgend. During the first half of 2016, the service area was rebuilt to offer a new amenity building and drive thru.

Design and History

The Days Inn hotel was built on a separate site with a driveway connecting it to the services.

Like many services on the M4, customer levels have increased, but not by as much as at other services. As a result, Sarn Park managed to miss out on funding, with parts of it falling into disuse. Competition from a huge retail development opposite made growth particularly difficult as other services turned to takeaway facilities to balance the books.

As a result, in 2013 plans started for a new, replacement services, which were built during the first half of 2016. This aims to increase custom by being more appealing to visit, and to help with maintenance as the original building had reached the end of its useful life. In truth, the old building wasn't compatible with Welcome Break's new tendency to offer only fast food in a food court which has the same styling at all their sites.

The whole services site is 5.67 hectares.

New Services

With the slip road running horizontally through the middle of the site, the redevelopment saw the amenity building and car park moved from the south side to the north side. This was to allow the old building to remain open while work took place. The new, square building, has a large zig-zag roof stretching well over the front of the building to create a small terrace. A Starbucks cafe with WHSmith behind it are on the left of the concourse, with Burger King on the right. The public toilets, game arcade and deliveries area is on the back wall.

Space has been left for a concession in the lobby, possibly Top Gift, and another in place of the picnic area if necessary.

As the site is on a downhill, the front of the building is well above the car park, with steps leading up to it. A Starbucks drive thru is included with a single window at the back.

As part of the works, a new Shell garage will gain a small Waitrose-branded retail store.

Although the swapped parking areas both offer more spaces than they used to, much of their alignment remains the same, with kerbstones being recycled.


Welsh motorway services rely on small sites by junctions which, owing to the geography surrounding the M4, are usually built north of the M4. As congestion around these junctions has increased, this creates difficulties for westbound traffic. Sarn Park exemplifies this.

Even travelling east, the road design requires users to complete a full lap of the services, before they can enter the car park.

Original Services

Detailing of one of the original amenity buildings.

The building design was very unusual, taking advantage of the small footprint and low traffic levels expected here. It consisted of three octagonal buildings; one disused, one offering toilets, and one a restaurant that was actually eight buildings and an extension all stitched together. The roofs on these buildings hung low, creating a design that appeared to surround the visitor.

In addition to the amenity buildings, there was a disused two-storey HGV MOT centre in the HGV parking area. The site was dug lower than the surrounding area to minimise noise disruption. Space was left on the roundabout for the hotel which was later added.

Planning permission for the services was originally granted in 1980, replacing the former East Glamorgan Hotel and isolation hospital. It included the option of extended both parking areas when necessary, but unusually this proved not to be required.

Some of the road signs were original to the site, and in 2015 included directions for "Commercials" - a word for HGVs not used beyond the 1980s.
