Longthorn Gardens is a newbuild development at Shawfair, Midlothian, delivered in partnership by Cruden Homes and Mactaggart & Mickel. The development brings 116 homes and apartments to the area, with a mix of two, three, four and five-bedroom houses alongside two-bedroom apartments.

SmartMist Fire installed water mist fire suppression at Longthorn Gardens. The system was planned around the build programme, installed with a discreet finish and handed over with clear documentation for the project team.

 

Project overview

 

The requirement

Longthorn Gardens includes two-bedroom apartments alongside family houses, so automatic fire suppression was a regulatory requirement for the relevant buildings.

The applicable technical handbook depends on the building warrant date and project type, so each project should be checked against the version of Standard 2.15 that applied when the warrant was submitted or the work started.

A development of this scale brings its own practical demands. With 116 homes, two developer partners and homes ranging from apartments to five-bedroom houses, the fire suppression work had to fit cleanly into a busy programme:

Cruden Homes is a five-star housebuilder, and the site team at Longthorn Gardens received an NHBC Pride in the Job Award in 2026. On a site held to that standard, the finish and tidiness of every trade matters, fire suppression included.

 

Why water mist

Water mist systems suppress fire with fine water droplets that control flames and reduce heat. As the NFPA notes, they achieve this with less water and smaller pipework than standard sprinkler systems.

Those characteristics suit newbuild housing. Smaller pipework is easier to route within ceiling voids and service runs, and small nozzles sit neatly within the finished home. Lower water flow also reduces the risk of water damage if the system ever activates, which is a real concern for homeowners, developers and insurers.

 

The result

SmartMist Fire completed the water mist installation at Longthorn Gardens. The completed installation gave the project team:

 

What developers can take from Longthorn Gardens

On a development of 116 homes with two developer partners, coordination is everything. Fire suppression touches design, service routes, ceilings, approvals and handover, so treating it as a late-stage add-on creates avoidable problems. Longthorn Gardens worked because the suppression work was planned into the programme with time to review the design, arrange access and confirm requirements well before handover.

If your development includes flats, maisonettes or shared residential use, ask three questions early. What does Standard 2.15 require for this building type? Is water mist suitable for the design? How will installation fit around the site programme?
