Height and levels
The steeper the garden, the taller the posts and the more levels and steps. This is usually the biggest factor in Durham.
Steps and guarding
Long flights, landings, handrails and balustrades are essential on slopes, and each is priced separately.
Ground and walls
Drainage, gravel and any retaining-wall repairs add to the cost but protect the deck.
Access
Carrying materials up steps or along narrow lanes takes longer.
Boards
Softwood is cheapest; composite and hardwood cost more but last longer and need less care.
Retaining walls
If an old wall near the deck is leaning or cracked, it may need repair before we build. We'll point it out at the survey and price it separately so you can see the cost clearly.
Lighting
Step lights and handrail lights are worth considering on any hillside deck. They're priced as their own item.
Building in stages
On a large terraced garden, building one or two levels now and the rest later can spread the cost. We'll design the whole scheme first so later levels join neatly.
How we quote
Every quote is written and itemised: frame and footings, bracing, boards, steps, guarding, drainage, lighting and any removal. The survey visit and quote are free, with no pressure.
FAQ
Do steep sites cost more?
Generally, yes, because of taller posts, bracing, steps and guarding. We'll show exactly where the cost goes.
Why does access matter so much in Durham?
Many hillside homes have no level route to the back garden, so materials are carried by hand. It adds time, which we include in the quote.
