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.
How does this suit sites in Hatfield?
Manufacturing businesses around Hatfield adding a dock to an existing building often find a loading house less disruptive than breaking out the slab inside. For older buildings in Hatfield with a raised floor and little internal space by the wall, an external house can provide a modern hydraulic dock without major alterations.
Racked warehouses around Hatfield that cannot spare internal floor space for a dock can move the leveller outside the wall into a loading house instead.
Before anything is ordered, we visit your site in Hatfield for a free survey and then send a written quote with a fixed price. From that point we manage the installation, coordinating delivery, access and any other trades. Fitting is done by specialist installation engineers engaged and managed by us, at times that suit your operation, including out of hours where agreed. You get a tested installation, a demonstration for your team and the manufacturer 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.
Does a loading house need planning permission or building approval?
A loading house can need planning permission, because it is a new external structure, so we check this at survey rather than assuming it is not needed. The answer depends on the site, the size of the house and any planning conditions already on the building.
Forming a new opening in the building wall is a structural alteration that may need approval. In England and Wales that means Building Regulations approval, in Scotland a building warrant, and in Northern Ireland building control approval.
Energy rules can also apply to the door in the building wall. In England, Approved Document L (2021) Volume 2 sets a limiting U-value of 1.3 W/m²K for vehicle access and similar large doors in new and replacement work. Wales, Scotland and Northern Ireland have their own energy rules, and we confirm the figure that applies to your nation and project.
The leveller inside the house is specified to BS EN 1398:2009, the dock leveller safety standard. Our guide to loading houses explained goes through the approvals in more detail.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- Clear opening width and height for each door
- Gaps around trailers where heated or chilled air escapes
- Escape routes and pedestrian doors close to the bay
- Asbestos register and any other site hazard information
- Access for deliveries, cranes or lifting equipment during installation
- Working hours, shift patterns and windows for out-of-hours work
Options to discuss
Leveller choice
A hydraulic swing-lip leveller for general trailer loading, or a telescopic-lip leveller for precise placement, end-loading and trailers that cannot be reversed tight to the dock.
Straight loading house
Set square to the building wall, the simplest layout where the yard has room for trailers to reverse straight in. Usually the most economical arrangement for one or more bays.
What do the rules in England mean for the work?
In England, Approved Document L (2021) sets a limiting U-value of 1.3 W/m²K for vehicle access and similar large doors in new and replacement work. That shapes door specification for sites in Hatfield, so we confirm the requirement for your project and check what applies at survey before recommending a door.
Questions about loading houses in Hatfield
Will you deal with building control and planning for a project in Hatfield?
We check at survey whether the work is likely to need approval. Forming a new opening or dock pit may need Building Regulations approval, a building warrant or building control approval, depending on the nation, and external structures such as loading houses can need planning permission. Where approval is needed, we explain what is involved, work with your designer or agent, and build it into the programme.
Can you work alongside our main contractor on a new build in Hatfield?
Yes. For new warehouses and fit-outs, we can supply and install the dock package as part of a wider project, working to the main contractor's programme, site rules and permits. We will need drawings, dock levels and the programme, and we coordinate pit details, power supplies and door openings with the relevant trades before installation begins.
Do you cover Hatfield for loading houses?
Yes. We take on loading houses for businesses in Hatfield and across Hertfordshire. We survey the site, provide a fixed written quote and manage the installation, with specialist installation engineers working under our management. Visits are arranged in advance at a time that suits your operation, and the same single contact stays with the job through to handover.
Is a loading house cheaper than forming an internal pit?
Not always. A loading house includes a whole steel structure, so the equipment cost is higher, but it avoids breaking out the slab and losing internal floor space. The best comparison is made at survey, taking account of racking, services under the floor and how the building will be used.
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.
