A way of removing rainwater away from your garden office is an important design element, and you should check that your chosen design includes one.
It is amazing how much water runs off a garden office roof, even a small one, and it is important to move this away from the structure of the building.
A guttering system is just as important on a flat roof garden office as a pitched roof design.
In its simplest form the garden office rainwater collection is a length of guttering at the bottom of the roof, connected to a down pipe which runs into a water-butt. This will collect the water from the roof and stop it moving into the structure of the building – you also have a good supply of rainwater to use on your garden!
On larger garden office designs a water-butt may not be sufficient to manage the water, some designers include larger or more than one water-butt to over come this, but the other option is to run the pipework into a soak away.
Your garden office may be sited close to the soak-away for your house, and you could direct the rain from the building to this. If not your ground workers should be able to dig a system for you.
A soak-away is a hole filled with gravel and is normally sited a few meters away from the foundation of your building.
Garden office designers have designed their own guttering systems
Whilst plastic guttering systems like those used on modern houses are the most popular and cost effective option, some garden office designers feel they spoil the visual appearance of their buildings, so have designed their own systems.
Hidden within the structure
Some suppliers have designed guttering systems on their flat roof designs that are invisible externally. They have hidden the down pipes within the wall structure of the garden office. The roof is sloped so that water is channeled into this hidden guttering which then runs down the pipe and exits into a soak away.
Other suppliers have created rainwater channels which are part of the roof covering and therefore invisible to the eye. With these systems there are few gaps for the water to escape and enter the building.
Some of these designs run into traditional style down pipes, whilst other designers have created metal lined channels into the wall structure which not only directs the water away but is a design feature in itself.
Its nice to think that so much attention is paid to a relatively small element of the build, this bodes well for the level of attention that other aspects of garden design have!
