The house is privately owned prestigious residential development overlooking Gleneagles’ famous Queen’s Golf Course, sold by the world-famous five-star hotel and golf resort in Perthshire.
The site, overlooking the third fairway of the Queen’s Course, is one of 13 in an exclusive gated development called Queen’s Crescent.
At 21,000sq ft, it will be about five times the size of a typical luxury five-bedroom detached home.
This incredible private home was built around an aquarium which is 4 meters in diameter and raises three stories through the centre of the property.
The stair is fabricated from a single steel helical stringer with cantilevering glass treads and glass balustrade to stairs and landing.
- The stringer will be connected to the floor structure using a steel base plate and supported off steel CHS columns (columns by others) at 3 other locations with fabricated brackets.
- The stringer will be a customised steel parallel flange channel (PFC) running around the outer edge of the stair with a plate infill welded into the open side and ‘post-box’ cut-outs to enable the glass treads to cantilever from the stringer towards the aquarium in the centre.
- The glass treads are to be wedge shaped heat soaked toughened laminated glass 40mm thick with structural sentry interlayer.
- The glass treads will be inserted through the stringer from the outside edge of the stair and held in place using high modulus silicon and nylon packers.
- The landing glass will be supported off the PFC stringer in a similar manner to the treads.
- The glass balustrade is to be heat soaked toughened laminated glass 15mm thick clamped between the stringer and a fascia plate.
- The design loads will be taken as 1.5kN/m2 floor load for a residential building and 0.36kN/m run balustrade loading taken in accordance with BS6399:pt 1.
- The target frequency of the stair will be 7Hz with 25% live load taken as participant mass. – This means that the stair will exhibit mild perceptible vibrations when trafficked energetically, which is normal for a stair of this type.
- It is assumed that the supporting structure has been designed with adequate stiffness and strength to support the proposed stair.
