When we moved into our house there was no driveway – instead the front of the house was occupied by a lovely cottage garden. However, with two cars and two toddlers, we really needed to be able to park outside the house so we decided to create some. Think driveway And removing the garden.
Our driveway sits at a high level that leads to the road, meaning the entrance to the driveway is very high. While this isn’t a major problem, it does mean that my son’s and husband’s cars, both of which are on the low side, often get crushed underneath, especially if there are passengers in the back because of the added weight.
We hope to widen the driveway later this year by removing part of the hedge that separates it from the road and I want to see if we can build it up a bit to reduce the slope at the same time. I asked the experts what the job would involve, whether it was feasible and how much I would have to budget.

How steep is the driveway?
Sloped driveways are not uncommon at all, but in cases where they are very steep or when homeowners want to turn uphill. Front garden in drivewayIt is important to understand that there are certain guidelines to consider before any type of excavation begins.
Guy Wall, Head of Marketing GCL Products explains. “For vehicular access, local authorities generally recommend driveways not be steeper than 1:10. Some local authorities will not allow crossovers, or drop curbs (where vehicular access crosses the pavement) where the hardstanding has a gradient of 15% (around 1:7) towards the highway, so it is worth planning ahead to understand exactly what is required by the local authority.
“When looking at paving options, drainage guidelines generally work for falls of up to about 1:60, depending on what the surface is intended for,” adds Guy.
Guy has some interest and experience in sustainable drainage, gardens and landscaping as well as solar and renewable technologies. Resin bound gravel, wet pore rubber surfacing and permeable surfacing are their specialties.
What should you do before leveling a driveway?
Before starting this undertaking, it is important to weigh the pros and cons and check whether or not. Driveway planning permission will need
In most cases, your driveway plans are provided Approved development Criteria, such as the use of permeable driveway materials, will not require a permit if your driveway exceeds a certain size. If you are building or replacing Falling controlYou will need to apply for highway consent.
As Guy Wall explains, it’s not just permissions you need to worry about in the early stages. “Perhaps the most important factor in leveling a sloping driveway is practical planning. Failure to plan properly can cause structural problems not only to the driveway but also to adjacent properties.
“Slopes should be measured to help assess the level of work required to level a driveway, plan drainage and determine whether this will be a large or small-scale project. Leveling a slope can be a significant undertaking so you need to know what you’re stepping into.”
What is involved in leveling a sloped driveway?
The exact opposite Exterior home makeoverLeveling a sloped driveway causes a significant amount of disruption, depending on how steep the site is – it’s wise to be prepared for this.
“In practical terms, leveling a sloped driveway usually involves a cut-and-fill approach,” prefers Guy Wall. “That means excavating higher ground, building lower ground, or using a combination of the two to create a safer and more usable finished level. On shallow slopes this may be fairly straightforward, but on overcrowded sites, the amount of spoil, the need for imported sub-bases, and the challenge of keeping new levels in place can often be a simple task where the work can quickly escalate. A significant groundwork project.
“Once the layers are set, the sub-base has to be properly constructed to support the new profile,” Guy continues. “This is one of the most important parts of the job, because a driveway on a slope will be exposed to vehicle loading, breaking forces and water movement. If the foundation is weak, the surface is more likely to sink, collapse or settle unevenly. The steeper the driveway, the less forgiving a bad foundation will be.”
Drainage and structural considerations
In our case, the issue is that the driveway is much lower than the road, meaning we’ll need to build it rather than excavate it. Either way, you need to give some thought to how the new layers will be supported, as well as ensuring that adequate drainage methods are implemented.
“If the driveway is being cut into a bank or built over surrounding land, some type of edge restraint or retaining structure may be required,” explains Guy Wall. “On mild gradients this can be as simple as strong curbing or edging. On more significant level changes, it can mean low Retaining walls or other structural support such as piling. This is a key design point, as driveway edges often have the hidden function of keeping the entire build-up stable.”
Guy explains it Driveway drainage becomes more important than before in case of sloping sites. “Drainage is one of the biggest problems with sloping driveways, and cannot be treated as an afterthought. Driveways need a controlled waterfall so that water does not sit on the surface or run towards the building. UK guidance for front garden surfacing says that a driveway should slope away from the house where possible, and if it slopes towards the house a drainage channel should be used to access the property.
“Where a driveway cannot simply drain water into an accessible area within the plot, drainage solutions may include channel drains. Driveway soakaway or impervious construction that manages water on site,” continues Guy.” It is also worth remembering that in England and Wales, surface water from driveways should not normally be carried onto a public highway unless planning permission is granted. Alternatively, using impervious paving as a wearing course will help reduce or eliminate runoff.”
How much does it cost to level a driveway?
As you might expect, as well Cost for new drivewayThe site is heavily hinged on the question of what you pay to level the drive and how much work will be required.
“A complete re-grade and resurface is the most complete fix,” says chartered architectural technologist Zaim Chaudhary, director. AC Design Solution. “This is where the existing surface is broken up, a sub-base is cut or built to create a gentle slope, and a new surface is laid. When taking this route, the most expensive part tends to be earth removal and excavation.
“These can cost anywhere from £8,000 – £20,000+,” continues Zaeem. “Ways to reduce these costs are to use tarmac, which is cheaper than block paving or resin, but doesn’t result in the best appearance.”

FAQs
How long does it take to level a sloping driveway?
The length of time it takes to level a driveway depends on the complexity of the job as well as the size of the space you’re dealing with and Driveway Design You have chosen.
“A simple driveway grade can be done in a week, but more complex slopes that require excavation, retaining work and drainage can take much longer,” says Guy Wall. “The timescale depends less on completion and more on the groundwork below.”
This Driveway material However you choose to finish your new driveway, some really careful consideration is required. Not only will they decide whether planning permission will be required, but they’ll also define how it looks, how much maintenance is required and what you’ll pay overall.
