The new terminal works are ongoing until 2017 when it is scheduled for completion. The view from our room would allude that there is still a long way to go. When we first checked into our room around 5pm and opened the curtains to see the construction zone we thought this is not good but we honestly couldn't hear a thing. The second night was horrendous and seemed to be metal on metal banging - perhaps pole driving/drilling - but we seem to be jinxed when it comes to noise inside or outside of hotel rooms on nights prior to flight departures! Perhaps contact the hotel and make an enquiry. We have stayed in both the Ambassador Transit Hotel within the airport - clean, functional, well priced - and I would be keen to try the new Aerotel. Depending on your arrival in SIN and your onward departure next day, you could stay at one of the transit hotels overnight and then spend the next day exploring Singapore. As previously suggested, book your luggage through to LHR and just take overnight bag with you which, if necessary, you could leave at left baggage in the arrivals area for the day for a small fee.
