Bus Shelter Construction Process
Learn how Littlethorpe bus shelters are constructed to the highest standards with our quick-reference guide.
Tudor timber framed building methods are emulated.
The robust construction of Littlethorpe bus shelters is achieved using durable, heavy timbers combined with traditional methods. Mortice, Tennon and Doweled joints are used throughout the main construction while computers are used for the design work.
Each component is carefully machined with modern machinery to a high degree of accuracy; this allows the finished product to be assembled in our factory with strong, tight fitting joints, quickly, neatly and safely, even though the shelters weigh about 1000kg each.
Tudor timber framed houses were built with heavy durable timbers using the same joints that are used in Littlethorpe bus and rail shelters. Littlethorpe also use durable heavy timbers and consequently except the life of the shelters to be very long.
The main timbers are square posts with rails jointed into them; the rails (combined with our traditional construction methods) are so strong there has never been an incident of a rail snapping even when the shelter has been subjected to abuse.
The vertical hardwood boarding is designed to accommodate natural shrinkage and expansion of the whole shelter. The exceptional thickness of the boarding was chosen to resist attack by vandals who may use anything from bricks and scaffold poles to karate style kicks to try and destroy any type of street furniture; so far we have not had a single board broken.
Littlethorpe shelters have in the past been hit by vehicles; the force that our shelters have been hit with has been enough to split the square posts down the middle, despite this none of the joints broke, which means the joints are actually stronger than the material they are made from. The shelters also stayed together thus not causing an urgent public safety issue.
We conclude; Tudor carpenters may not have benefited from computers but they knew a lot about joinery.
Visually balanced, strong and durable.
Mono pitched roofs:
The main roof decking consist of pressure treated softwood planks, the planks are glued together to form one very strong surface which is screwed down to the main part of the bus shelter frame. The whole roof is then covered with special galvanized steel sheets which have a plastic coating bonded to it. The sheets are bent to form a seamless joint at the edges of the roof. This type of roof covering is considerably more durable than a felt roofing system.
The whole roof is strong enough to carry a considerable weight; either a snow load or a number of people should they climb onto the roof for reasons of maintenance or of mischief. The steel roof covering is not only durable against the weather but also against deliberate damage; it can not easily be bent at the edges, prised up or pierced.
Pitched roofs with gabled ends:
The gable ends are built from solid FSC® certified hardwood. The roof substance is the same pressure treated softwood as the mono pitched roofs and screwed down in the same thorough way; the roofs are edged with a plastic coated galvanized steel facia, it is important that the softwood is protected from the weather, especially the end grain.
The underside of the roof has an open void; the underside of the roofing planks are sprayed to match the hardwood and can be seem from below, this forms an attractive feature.
Once the roof structure has been formed it is very strong and is ready for the final covering, which is usually cedar shingles, these are a wooden tile made from cedar. Cedar shingles are the roof covering of choice in much of North America and Canada and have a life span of forty to fifty years.
Pitched roofs with hipped ends :

The hipped roofs have a solid flat ceiling, this overhangs the main shelter and is edged with a plastic coated galvanized steel facia, unlike the gabled roofs there is no open roof void.
The structure of the roof pitch is made as a traditional "cut" roof softwood timbers for the common rafters and hip rafters. This strong roof is braced further thick plywood sheets that form the under surface onto which the cedar shingles are fixed.
If a Littlethorpe shelter with a pitched roof is installed in an area where local slate or stone, feature predominantly in the architecture, this local roof covering may be specified in preference to cedar shingles.
Hardwood - warm in winter, cool in summer.

Bench seating is factory fitted to all shelters except the "Cropston" as a standard fitting. It is fitted at a height of 500mm from the ground and runs along the rear wall of the shelter.
A different height may be specified by request.
The seating consists of thick FSC® certified hardwood planks supported at each end and in the centre. The Cropston style of shelter does not have a seat as standard because it is usually installed where there is very little room on the pavement.
A seat can be added to the Cropston as an extra item.
Safety glazing is standard.
Laminated safety glass is fitted as standard.
The glazing system is "vertical shuffle glazing" secured with hardwood beading and silicon down both sides. There is no horizontal beading to trap water or to get perished by the weather.
The hardwood beading on the sides are secured with stout brass screws, our thinking, which has so far proved correct is; if it takes a strong man with a large screw driver to put the screws into the wood, a kid with a Swiss army knife will not be able to take them out again. In addition the glass won't come out by itself even if the beading has been removed because the glass is also stuck in with silicone.
Extra thick toughened safety glass is available as an optional extra and includes a 12 months money back guarantee should breakage occur. Our thinking is; if the glass is robust enough to remain unbroken in the first year there is a high probability it will give the same performances in each subsequent year.
Polycarbonate or any other glazing material can also be fitted as alternatives to real glass.
See our Guarantee page regarding glazing and breakages.
