Our client was refurbishing a house on the outskirts of Aberdeen, overlooking rolling fields.
Part of the internal structural work involved creating an opening at first-floor level to allow access to a new balcony and a space-saving way to descend to the garden below.
The balcony would provide elevated outdoor space and let them enjoy the relaxing scenery. A spiral staircase was the obvious choice for the stairs, as it only takes up as much space as its diameter.
The spiral supported one corner of the platform, with a vertical post supporting the other, and glass infill panels between steel newels ensured the views remained unobstructed.
Brief:
- Provide a space-efficient way to access the rear garden from the first floor
- Create a raised balcony area with enough room to sit out
- Use steelwork with a weather-resistant finish
- Ensure the stairs have wide enough steps for frequent use
Solution:
- A bespoke steel spiral staircase
- A rectangular platform supported by the center column and an additional post
- Fully galvanised finish for weather protection
- A 1800mm diameter spiral staircase with an 800mm clear tread width
