SINGAPORE – Two HDB blocks in Punggol and Toa Payoh will have their air-conditioner ledges covered in netting to stop pigeons from landing and building nests there.
This is part of a trial to prevent pigeons from affecting residents and study how different air-con ledge layouts and configurations affect bird nesting behaviour, HDB told The Straits Times.
The Housing Board on Dec 1 called a tender for the design, supply and installation of the netting, which will be installed at 35 units – one stack of 15 flats in Punggol and another stack of 20 in Toa Payoh. The exact blocks have yet to be finalised.
Tender documents on government procurement portal GeBIZ stated that this netting should be fire-resistant and have top covers and sides that can be opened for maintenance.
It should also have enough ventilation to prevent hot air build-up from the air-con condenser unit, and not obstruct clothes drying racks.
HDB said Punggol and Toa Payoh were selected for the study after consulting town councils, which typically receive reports of pigeons nesting at air-con ledges from residents.
The study is expected to start in the first half of 2026 and be carried out over 13 months.
First, the netting will be tested at a mock-up unit at HDB’s Centre of Building Research.
