Case Studies

Supreme Loft Ladder with deep hatch box for suspended ceiling. Premier Loft Ladders

Suspended ceiling hatch and loft ladder

Premier Loft Ladders helped Horizon Construction provide a safe and convenient access solution to a 1st floor plant room within a premium car showroom. What made this project particularly challenging was the 1.8m deep ceiling void. In addition, the access point was also in a prominent location outside the showroom offices.

The Supreme loft ladder offered the perfect solution. The heavy duty concertina loft ladder featured a bespoke, deep hatch box. As a result, it provides safe and easy access to the car dealership plant room.

The Supreme loft ladder provides easy access to loft for everyday use in family home

Sam Beardsley Carpentry, had a client needing a high-spec loft ladder for everyday use in a brand new home. Already familiar with Premier Loft Ladders, Sam got in contact to discuss his project and review the available options. The Supreme was the obvious choice based upon the needs of Sam’s client. The end result was a loft ladder that they were ‘over the moon with’.

“The main thing I liked about Premier Loft Ladders were how quick they were in response to any questions I had.”
