We do offer a nationwide installation service. We can discuss your requirements and liaise with landscapers where needed. The slate sphere is constructed in sections in order to make installation less complex. All of the sculptures are built so that they can be installed by two people, without lifting equipment.

Description

A stunning full sphere using the grey slate from the Cornish quarry. Each piece has been handcrafted to its unique shape so that it helps to form this tactile, mesmerising water sphere. A light grey when dry, is transformed into the striking dark grey. This often suits the more modern garden or courtyard, often complimenting structures such as summer houses and work spaces in the garden made from dark steels or Aluminium.

A stunning full sphere of handcrafted slate pieces, meticulously placed together to form a beautiful feature. The majority of installations have the sphere at ground level, sometimes among planting, integrating it into the garden. It is also possible for the sphere to sit at water level, over a pool. Our spheres can be made in sections which allows us to install in a variety of properties, even where there is no rear access to a garden. We have installed in courtyard gardens in Notting Hill where the only access was through a house, to roof terraces in London.

Details & Specifications

Below is some detailed information about our water feature and how they work and how they are installed.

Water feature location

The slate sphere feature can be situated anywhere in the garden; for water features or light sculptures you will need an electrical supply. Although the products are all heavy, the they are created in sections so that they can be lifted into position by two people, thus avoiding the need for any heavy lifting equipment.

Pond Installation

It is an option for all the slate sphere feature to sit at the water level in a pool. The best way to do this is to use a concrete pillar to support the sphere at the desired height. If you are considering a pond water feature, please contact me to discuss your requirements.

Water feature sump

The majority of installations site the slate sphere at ground level with a sump reservoir buried below. The sump reservoir is filled with water. It collects the water below the water feature as it flows off the slate sphere. The pump in the reservoir pumps the water back out of the top of the feature. The sump has a lid that is covered with slate pieces.

Frequently Asked

Here are some frequently asked questions

Can I choose any size in either of the two types of slate?
Yes, during the consultation process we ask for the size and type of slate you would prefer.
How do the features work?
The water features are self contained units. The Watersphere™ sits on top of a sump reservoir that is filled with water. The pump that sits in the sump reservoir, pumps the water up the centre of the feature. The water then cascades down around the sphere and falls back into the sump. The sump reservoir can be hidden and buried in the ground or it can sit at ground level and we provide a steel edging (at a small extra cost) to cover the sump reservoir?
