Measure the complete parking envelope
Begin with the caravan model and towing vehicle rather than a rectangle copied from an online plan. Record overall length, width and height using the manufacturer's information and the actual accessories fitted. An awning, spare wheel, drawbar storage box or roof-mounted equipment can change the space required. Keep the tow vehicle measurements beside the caravan information because the combination controls the manoeuvre into the property.
The useful parking envelope also includes things that open. Mark the entry door, storage hatches and any side that needs routine access for loading, cleaning or maintenance. A caravan can fit between a fence and house while leaving the door unusable. Draw a separate walking route rather than assuming people can squeeze through whatever space remains. Think about carrying bags or a portable step, not just standing sideways beside the van.
If you have not chosen a caravan, compare a small group of realistic models and identify the largest practical envelope. That is more useful than adding arbitrary spare space everywhere. State clearly which vehicle the proposed pad is based on. Future flexibility should be a deliberate design choice, with room allocated where it helps, rather than a vague promise that the pad will accommodate anything.
Rehearse the approach before fixing the pad shape
The tyre path during reversing rarely follows the final parked outline. The towing vehicle swings, the caravan tracks differently and the rear overhang moves towards obstacles. Gate posts, letterboxes, trees and the edge of an existing driveway can become the limiting points. Photograph the approach from the street and from the intended parking position so the contractor can understand both ends of the manoeuvre.
Where a safe trial is possible on a suitable existing surface, use cones or removable markers to explore the route at low speed with appropriate assistance. Do not drive a heavy vehicle onto unknown soft ground to prove it fits. A marked sketch and vehicle information can instead support a professional swept-path assessment. The goal is to identify the area that must carry wheels, not merely the area beneath the parked body.
A driveway widening may need a broader entry or turning section than its final parking bay. Discuss this before comparing concrete quantities. A smaller pad that requires repeated wheel movements over a weak edge can be a poor trade. For a Rockhampton home with limited frontage, the approach geometry may determine whether side parking is practical at all, even when there appears to be ample space behind the gate.
Explain loads and support points to the designer
Give the person designing the pavement the actual vehicle information, including intended loaded use. A caravan used for storage between trips may still arrive loaded. Do not describe it only as a light trailer without checking the specifications. The designer also needs to know whether the pad will carry another vehicle, delivery access or workshop equipment in future.
Tyres are not the only contact points. A jockey wheel, stabilisers and other supports can concentrate forces over smaller areas, depending on the caravan and how it is used. Record their locations and follow the caravan manufacturer's operating instructions. Stabilising equipment should not be treated as lifting equipment unless the manufacturer expressly permits that use. Discuss support arrangements before selecting the slab detail or assuming loose pavers solve the issue.
A homeowner brief should identify these demands without trying to calculate slab thickness from vehicle weight alone. Ground support, pavement geometry, joints and edges all matter to the design. Ask who is responsible for translating the vehicle information into the concrete specification. If the quote simply says standard driveway, request confirmation that the intended caravan and support points have been considered rather than leaving that understanding implicit.
| Stage | Space to check | Useful evidence |
|---|---|---|
| Approach | Gate opening, roof clearance and turning path | Photos and actual vehicle dimensions |
| Reversing | Tow vehicle swing and trailer wheel route | Slow trial on a suitable existing surface |
| Parked | Doors, storage hatches and walking route | Layout with openings marked |
| Unhitched | Support points and towing departure | Manufacturer information and marked positions |
Resolve the existing edge and new ground together
A widening often replaces lawn or a garden strip beside older concrete. That ground may have a different history from the original driveway foundation. There can be irrigation trenches, roots, loose fill or buried services. The existing concrete edge may also be damaged or unsupported. A neat visible connection does not prove that the two areas will perform together.
Ask the contractor to describe how the old edge will be assessed and how the new foundation will be prepared. The connection may need to accommodate movement, transfer load or remain independent, depending on the design. Do not prescribe drilling and tying the slabs together as a universal improvement. The appropriate detail depends on the condition and purpose of both pavements.
Locate the proposed wheel tracks relative to the joint and outside edge. If the caravan repeatedly reverses with a tyre close to the perimeter, make that clear. The edge detail and adjacent ground should suit that loading. Consider how grass, gravel or landscaping will finish against the new concrete without leaving a drop that catches feet or channels runoff under the pavement. These interfaces are easier to resolve before excavation than after the pad is poured.
Balance parking level with water movement
Caravan setup and driveway drainage are different requirements that have to work together. Discuss the manufacturer's guidance for parking and using the caravan, then explain how the surrounding paved area will shed water. Avoid assuming that a perfectly flat slab is the only answer, or that a strong slope can always be corrected later with accessories.
Mark where runoff currently leaves the garden or driveway. Replacing a permeable strip with concrete changes the surface route, particularly beside a house or fence. The new pad should not close the only low passage through which water escapes. Existing downpipes and drain covers need to remain accessible after the caravan is parked, including when a cover must be lifted for cleaning.
Rockhampton's subtropical setting makes rain planning relevant, but the design still needs the levels of your particular property. Ask for the proposed direction of water movement on the same drawing as the parking outline. That exposes conflicts early, such as a low drain beneath the caravan or a flow path crossing the usual access step. A coordinated drawing is easier to assess than separate verbal assurances about parking and drainage.
Keep the household usable when the caravan is home
A pad should work on an ordinary weekday, not only when the caravan is being parked. Check whether bins can reach the street, the side gate opens fully and people can move from the front to the backyard. If the caravan blocks the only route for a mower or garden equipment, include an alternative route in the plan rather than treating it as a future inconvenience.
Think about servicing and loading. Identify where the towing vehicle waits while the caravan is connected, where people stand and whether the garage remains accessible. A pad that fits the caravan but leaves no space to couple it can create awkward movements every time you travel. Keep the route clear of fixed garden features that are likely to be added after the concrete work.
Consider shade, cleaning and visibility without assuming new structures are part of the concreting job. If a future shelter is likely, flag it before the pavement design is settled because its supports and layout may require separate design. Outdoor power or other services should be planned by the relevant trade. Do not embed improvised service arrangements in a slab and expect them to be easy to change later.
Hypothetical example: widening a side driveway
A household has a driveway beside the house and wants a concrete strip for a caravan. Their first sketch shows a long narrow rectangle that closely matches the caravan's parked width. When they add the tow vehicle and gate opening, they find the reversing tyres need more room near the front. The narrow rectangle would save concrete but leave the wheels travelling across the garden edge.
They revise the brief to include a wider entry section, the final parked position and a clear route for bins. The caravan door is marked open, revealing a conflict with the fence. Moving the parked position slightly allows access, but places a support point near the proposed joint. That becomes a design question for the contractor rather than something discovered after the concrete has cured.
The homeowner requests a scope that includes foundation preparation, the connection to the existing driveway, drainage and reinstatement of the garden edge. Vehicle details accompany the quote request. The resulting comparison is based on a functioning parking arrangement. It may involve more concrete than the first sketch, but each additional area has a stated purpose: turning, support or access.
Avoid shortcuts that restrict the finished pad
The most common planning error is measuring only the caravan body. The remedy is to draw the approach, openings and departure of the tow vehicle before fixing boundaries. Another is treating a heavy parking use as identical to occasional foot traffic because both are beside the house. Resolve the actual use in the written brief and ask the designer to confirm the pavement specification.
Do not let finish selection distract from geometry. A decorative surface will not make a gate wider or protect a tyre travelling beyond the supported edge. Choose the layout first, then discuss texture, cleaning and visual connection to the existing driveway. If the extension will look different, an intentional border or panel division can be easier to live with than an unachievable promise of an invisible match.
Before accepting a quote, ask what information remains provisional, who confirms the design and how vehicle access will be managed during construction and curing. Keep the caravan elsewhere until the contractor confirms the surface is ready for its intended use. The downloadable brief below collects the main planning inputs. Use it with your measurements so the conversation starts with a specific vehicle and an achievable route.
