Points to plan for in Lisburn
Noise
Fans and grilles are selected and attenuated to keep noise down.
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.
Building Regulations
New or altered ventilation in Northern Ireland must meet Technical Booklet K. We design to it and hand over the commissioning records.
Conservation areas
Historic streets and listed buildings in and around Lisburn are more likely to need planning permission for outdoor units on visible elevations. We check with the council's planning service before work is booked.
