What methods are available (in the UK) to get building supplies (listed below) to a site at the end of a steep (1 in 2.25 in parts) grass track. Given that a lorry or van would have a near zero chance of traversing the track in its current state, as the grass is far too slippery.
I will access the property day to day by quad-bike with large shallow tread tyres to prevent the track turning into a mud slide. As this domestic only access will mean at most a couple of trips a day, the track shouldn't get churned up. However repeated trips in quick succession with vehicles carrying heavy building materials would quickly damaged the grass track. I would like to keep the grass track at all costs, so laying down a concrete or aggregate surface is not a popular option with me.
The project is a renovation. The building that is on site is in relatively good repair (awaiting structural survey) and only internal work will be required (fingers crossed).
The property is 520 metres (±15 metres), as the crow flies, from the nearest public road. From the road there is an overall vertical drop of 35 metres (±2 metres). Any zip wire would have to cross a valley which at its deepest would be 60 metres (±2 metres) below the height of the zip wire. Such a zip wire passes over the land of a landowner who is happy to have a zip wire flying overhead but not with any structure on the ground that interrupts their grazing animals. (Added this detail in response to A. I. Breveleri's greatly appreciated answer.)
I would be grateful if you could provide these 3 things: A description of the solution, An order of magnitude cost, Any other information or experience you feel is relevant.
The building supplies will likely include:
- Windows [I am most nervous of this]
- Small timbers, for floor support
- Breeze blocks
- Concrete (in it's liquid form) for flooring
- White goods
- A kitchen (Not pre-assembled obviously! However funny for everyone watching that would be.)
- Doors
- Carpets
The building supplies will not include:
- Bricks or stone for external stonework (there is a building on site already)
- Roof tiles/slates (the roof on the building is in a good state of repair)
The (possibly crackpot) ideas that I have had are:
- Cover the track in a temporary road surface, which would provide grip and hopefully prevent the grass from being damaged.
- A zip wire of sorts with a bucket or other container to hold materials.(There is line of sight between a public highway and the property)
