Reports needed for a dropped kerb and front parking
Laying the driveway and crossing the footway are two different permissions. Here is what the permeability condition requires, what the highway authority checks, and which reports you need.
Most front parking schemes need no technical reports at all. What they need is two separate permissions that people routinely confuse: the right to lay the hard surface, which is usually permitted development if you get the drainage right, and the licence to cross the footway, which always comes from the highway authority under its own process. A dropped kerb front garden parking project fails far more often on the second than the first.
So the honest document list for a typical suburban house is short: a crossover application to the county or unitary council, a drainage detail, and drawings. The reports appear only where a tree, a classified road or a designation is involved.
When hardstanding is permitted development
Class F of Part 1 of Schedule 2 to the General Permitted Development Order 2015 permits hard surfaces within the curtilage of a house for a purpose incidental to its enjoyment. A parking area qualifies.
One condition does the work. Where the hard surface would sit on land between a wall forming the principal elevation of the house and a highway, and its area is more than five square metres, it is only permitted development if the surface is made of porous materials, or if provision is made to direct run-off from it to a permeable or porous area or surface within the curtilage.
That is the five square metre rule people half remember. It does not mean you can lay five square metres of concrete and no more. It means a front surface larger than five square metres has to deal with its own water, either by being permeable or by draining to somewhere within your own garden that is.
Permitted development rights can also be removed. An article 4 direction, a condition on the original planning permission for the house, or a flat rather than a house all take the project into a planning application.
Meeting the permeability requirement in practice
Three routes work.
Permeable block paving on an open graded sub-base, designed so water passes through the joints and is stored in the sub-base before soaking away. The sub-base is the part that matters and the part most often omitted by a driveway contractor pricing on area.
Gravel over a geotextile and a granular layer, retained at the edges. Straightforward and inexpensive, and it needs a kerb or edging that actually holds it.
An impermeable surface, laid to fall towards a soakaway, a French drain or a planted border of adequate size within the curtilage. This is the route that needs a little design: a soakaway sized for the contributing area and tested for infiltration, and enough garden left to take it.
What does not work is falling the surface towards the street. Water discharging onto the highway can be required to be stopped by the highway authority under the Highways Act 1980, and it also removes the permitted development protection.
The crossover is a separate application
Lowering the kerb and strengthening the footway is work in the public highway, and it is carried out under section 184 of the Highways Act 1980. Apply to the highway authority, which is the county council in two-tier areas and the unitary or London borough elsewhere. The authority inspects, quotes and usually carries out the work itself or through an approved contractor at your cost.
Expect the authority to check the width of the proposed crossing, the depth available on your side to park a car clear of the footway, visibility in both directions, the position of drainage gullies, lighting columns, telecoms chambers, street trees and parking bays, and whether the road is subject to waiting restrictions.
Two points are worth knowing before you apply. A vehicle has to be able to stand entirely within the curtilage, clear of the footway, which on a shallow front garden is the usual reason for refusal. And where the road is classified, the formation of the access itself needs planning permission as well, because permitted development rights for a new access do not extend to a classified road.
Visibility, and the things in the way
Highway authorities publish visibility standards in their own design guides, usually expressed as a set-back from the carriageway edge and a sight distance along it related to the speed limit. Check the local guide rather than a national figure, because they differ.
Obstructions are the practical problem. A street tree in front of the property is owned by the council and will not normally be removed for a private crossing. A lighting column or a telecoms chamber can sometimes be moved at the applicant's cost, which is rarely modest. A parking bay or a bus stop clearway usually ends the discussion.
Trees in your own garden are a different matter. If the tree is protected by a Tree Preservation Order or stands in a conservation area, works affecting it need consent or a notice, and construction within the root protection area needs a no-dig method. That is where a tree survey and an arboricultural method statement come in, and they are the only technical reports most of these projects ever need.
Surface water, and where it must go
The drainage answer has to be inside your boundary. Infiltration where the ground allows it, with a soakaway sized for the area being drained and located a sensible distance from the house and the boundary, or a permeable surface that stores water in its own sub-base.
Where infiltration is not viable, because of clay, a high water table or contamination, the options narrow and a connection to a surface water sewer needs the undertaker's consent. On a small front garden that is often the point at which a permeable surface becomes the simpler answer. A full Drainage Strategy is a document for a development site rather than a driveway, and understanding the hierarchy it applies is still useful here.
Conservation areas, article 4 directions and listed buildings
In a conservation area the hard surface itself may still be permitted development, and the front boundary wall usually is not. Demolishing or altering a wall, gate or railing can need consent, and in many conservation areas an article 4 direction has removed the relevant rights altogether.
Where the house is listed, the curtilage and any boundary wall within it are likely to be covered by the listing, and listed building consent is needed for works affecting them. A Heritage Statement assessing the significance of the wall and the effect of removing part of it is then required, and a scheme that takes out a section of historic railing for a car will struggle.
The document bundle
For the crossover: the highway authority's application form, a location plan, a dimensioned sketch showing the proposed crossing width and the parking space behind it, and photographs of the frontage.
Where planning permission is needed as well, because of a classified road, an article 4 direction, a flat or a removed right: the application forms, a location plan with the site edged red, a block plan showing the surface and the drainage arrangement, a drainage note explaining the permeable construction or the soakaway, and a visibility drawing where the highway authority has asked for one.
Where a protected tree is affected, add the arboricultural work. Where the property is listed or in a conservation area, add the heritage assessment and any separate consent application. Nothing else is usually required, and an applicant being asked for a transport statement for a single domestic crossing should ask why.
If you are also installing a charge point, our note on reports for an electric vehicle charging hub covers the larger version of the same questions, though a domestic wall-mounted unit is normally permitted development in its own right.

Frequently asked questions
What is the five square metre rule for front gardens?
Where a hard surface between the principal elevation of a house and the highway exceeds five square metres, Class F of the permitted development order only allows it if the surface is porous or if run-off is directed to a permeable area within the curtilage. It does not limit you to five square metres of paving; it sets a drainage condition above that area.
Do I need planning permission for a dropped kerb?
Not usually for the hard surface, but the crossing itself is work in the public highway and needs a separate application to the highway authority under section 184 of the Highways Act 1980. Where the road is classified, the formation of the access also needs planning permission, because permitted development rights for a new access exclude classified roads.
Why do highway authorities refuse crossover applications?
Most often because a vehicle cannot stand entirely within the curtilage clear of the footway, which rules out shallow front gardens. Other common reasons are inadequate visibility, a street tree or lighting column in the way, a parking bay or bus stop clearway, and drainage gullies or utility chambers at the proposed crossing position.
Can I drain the driveway to the road?
No. Water discharging onto the highway can be required to be stopped by the highway authority, and directing run-off to the street also removes the permitted development protection for the surface. The drainage answer has to sit inside your own boundary, through a permeable construction, a soakaway, a French drain or a planted border.
What if there is a protected tree in the front garden?
Works to a tree covered by a Tree Preservation Order need consent, and works to a tree in a conservation area need a notice to the council. Construction inside the root protection area needs a no-dig build-up above existing ground level, specified in an arboricultural method statement. These are the only technical reports most driveway projects require.
Does a conservation area stop front parking?
Not automatically. The hard surface may still be permitted development, though altering or removing the front boundary wall, gate or railing often is not, and many conservation areas have article 4 directions removing the relevant rights. Where the house is listed, the boundary wall is likely covered by the listing and needs listed building consent.
