Points to plan for in Walthamstow
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Leased premises
If your Walthamstow 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.
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
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.
Typical premises in Walthamstow
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
