Drainage is a design decision
A permeable surface is only as good as what lies beneath it. Ground conditions vary from street to street and even within a garden, so we would not assume how quickly water will soak away without looking.
Where infiltration is uncertain, the design can include a deeper open-graded base, a soakaway, or channel drains that collect water and lead it somewhere suitable. You should know which approach is proposed and why.
Bungalows and level access
Many Hoddesdon households want step-free access to the front door, for now or for later life. A resin bound or tarmac surface can be laid to gentle, consistent falls that make wheelchairs, walkers and buggies easier to use.
Getting a level threshold without driving water towards the door needs careful detailing, usually a slot or channel drain at the doorstep.
Mixing materials sensibly
On larger frontages a combination often works well: tarmac for the main parking run, resin bound for the path and entrance area, and a shared border tying them together. It keeps cost sensible while putting the more refined finish where people walk and look.
