Multiple Houses

Multiple house builds are on the up, and across the country. With large developments, there are always areas of the builds that become challenging and whether it be for an open-plan layout, or because the property is too far from the nearest accessible road, a fire suppression system may be needed.

These builds are typically in the 10s of houses and usually take place between 12-18months.

A fire suppression system could mean more properties can be built with compensatory measures, and the layout that the architect is hoping to achieve can still be met.

When do I need a fire suppression system?
