Points to plan for in Heston
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Future use
Allow for growth in occupancy or IT load.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
