A loading house is an insulated steel structure built against the outside wall of a building, containing a dock leveller and usually a shelter or seal at its front. The building door closes at the wall line, while trailers dock against the house. Loading houses suit buildings whose floor is at dock height but which have no room inside for a leveller pit.
Why do sites in Gwynedd choose this?
For older buildings in Gwynedd with a raised floor and little internal space by the wall, an external house can provide a modern hydraulic dock without major alterations. Where a yard in Gwynedd is narrow, an angled loading house lets trailers approach on a diagonal and can sometimes fit more bays along one wall.
Any loading house proposed in Gwynedd needs its planning and building control position checked, which we look at during the site survey before quoting.
A single contact at Loading Bay Doors handles your project in Gwynedd from start to finish. The free site survey and fixed written quote come first, with no obligation to proceed. We then book the installation for times that suit the operation, including out of hours by arrangement, and manage the specialist engineers on site. At the end we commission and test the equipment, walk your team through it and provide the documentation.
What is a loading house made of?
A loading house is a steel frame clad in insulated composite panels, with a dock leveller built into its floor and a shelter or seal across its front. It is made to suit your building, trailers and yard rather than bought off the shelf.
- Frame: galvanised or painted steel, supported on legs or a sub-frame that sits on concrete foundations.
- Walls and roof: insulated composite panels, usually colour-matched to the building cladding, with guttering to carry rainwater away.
- Floor and leveller: a steel deck with a hydraulic swing-lip or telescopic-lip leveller set into it.
- Front: a retractable or inflatable shelter or a foam seal, with bumpers below to take trailer impact.
- Building door: an insulated sectional door in the original wall opening, closing the building when no trailer is docked.
- Extras: internal lighting, dock lights and traffic lights as required.
The insulated envelope reduces the heat or chill lost around the trailer compared with an open dock.
What happens on site when a loading house is installed?
Installing a loading house takes the bay out of use from the foundation works to commissioning, but the building can stay secure because the existing wall and door remain until late in the job.
- Foundations: concrete pads or footings are formed in the yard and left to cure.
- Erection: the steel frame is lifted into place, usually by crane, and fixed to the foundations and building.
- Cladding and equipment: panels, leveller, shelter or seal, bumpers and lights are fitted.
- Door and electrics: the building door is fitted or adapted and the leveller and lights connected.
- Commissioning: everything is tested with a trailer before handover.
We ask you to provide yard space for the crane and deliveries, any drawings of drains or buried services, a power supply, and clear arrangements for keeping vehicles and people away from the lifting zone. Neighbouring bays may need to close briefly while the crane is working.
Towns we cover in Gwynedd
Each of the following towns in Gwynedd has its own page on loading houses, covering how we work and what to send us.
Budget range for supply and fit. The written quote after a free survey is the fixed price. All guide prices.
Which rules apply in Wales?
Equipment fitted in Wales may carry the UKCA or the CE mark. For each door, leveller or shelter installed in Gwynedd, we hand over the documentation that comes with it. Permissions are never assumed either way: whether planning permission or Building Regulations approval is needed, we check what applies at survey and tell you before dates are agreed.
Questions
What details do you need from us to quote for loading houses?
To get started, send the site address in Gwynedd, the number of bays or openings, approximate sizes, and photos of the dock from inside and outside. Tell us what vehicles you load, what goods you handle and any temperature requirements. Drawings help on new builds. We then arrange the free survey and confirm the details before the written quote is issued.
Is the site survey in Gwynedd free?
Yes. For new installations, replacements, upgrades, conversions and complete bays, the site survey and written quote are free and come with no obligation. The survey lets us measure the openings, check the dock and structure, and understand how the bay is used, so the quote reflects your site. Repair and servicing visits are different: they are chargeable, with the price agreed before anyone attends.
Can a loading house be used for a cold store?
Yes. Loading houses suit chilled and frozen operations because the building door closes at the wall line, keeping the cold space sealed when no trailer is docked. The panels, door and shelter or seal are specified to suit the temperatures involved, which we confirm at survey.
Can a loading house be moved later?
Loading houses are bolted steel structures rather than masonry, so in principle they can be dismantled and moved if your needs change. In practice, relocation needs new foundations and an opening at the new position, so it is usually considered only where a house is fairly new and the new position suits it.
