Ground screws overcome a sloping site

A garden office on the top terrace of a Kent garden with a 1.7m fall, set on 1.5m ground screws.

The garden office was built on the top tier of the garden
Ark Design Build  office on the top terrace

Ark Design Build was recently commissioned to construct a garden office in a Kent garden. While that’s not unusual, the challenge was the steeply sloping garden, with a 1.7-metre difference in height from the top to the bottom.

The garden had already been terraced, and Ark Design Build’s client chose to place the garden office on the top tier.

After contacting several companies, most were discouraged by the slope. However, the Ark Design Build team welcomed the challenge.

We’ve featured several other projects where Ark Design Build successfully tackled sloping gardens, including:

  • Garden Office and Shed Combo
  • Garden Studio Built on Terraced Ground
  • Garden Room with Large Side Canopy
  • Garden Office with Storage on a Sloping Site
  • Garden Room for All the Family

At a glance

  • Site: A terraced garden with 1.7m between top and bottom.
  • Built for: A home office.
  • Construction: 1.5m ground screws, installed in a few hours.
  • Finishes: Plaster inside, with brushed steel fittings, data cabling and heating.
  • Company: Ark Design Build, who took on a slope others turned down.

Foundations

Ground screws were the solution

In a terraced garden like this, the ground is often too soft for many types of foundations.

After assessing the site, the Ark Design Build team determined that ground screws were the ideal solution. The length of the screws varies depending on the ground conditions and how deep they need to be drilled to reach solid ground.

For this project, 1.5-metre ground screws were selected. These were spaced evenly across the footprint of the garden office.

Ground screws are a great option because, even on complicated sites, they can be installed in just a few hours, allowing construction to start immediately.

Turnkey project

Ark Design Build offers their projects on a turnkey basis, managing everything from the initial design to the final decoration.

They also handle the mains electrical connection, a service that many companies ask you to organise separately.

The electrical specification is comprehensive. Brushed steel fittings are used throughout, and data cabling is included as standard for a reliable internet connection. Heating is also a standard feature-something often treated as an extra by other companies.
