Points to plan for in Harrow
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Leased premises
If your Harrow premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Coordination
Ceiling, lighting, sprinkler and electrical layouts are coordinated early.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
