Stair Layouts From the coding and dimensions, a quotation can be produced after which a full onsite survey can be undertaken if required, with detailed dimensioned drawings provided as a matter of course.
Based on many years of experience working with architects, quantity surveyors and builders, we have tabulated many of the most popular staircase configurations which can be specified with a simple coding system.
Typical Straight 13 Up Total Going 2676mm
An addition to the stair layout shown, there is a huge selection of made-to-measure options, plus other timber options such as Ash, Oak and Beech.
20 preferred layouts have been recorded on the following pages, together with the critical dimensions relevant to each layout, including the trimming dimension necessary to obtain headroom clearance.
If required, our team of stair specialists is always on hand to offer help, and advise on any aspect of stair design or construction or Part ’K’ of the Building Regulations. They can be contacted on 01664 484613 or fax 01664 484582.
These calculations are based on a total rise of 2588mm, 226mm Go – 13 Up, but by referring to the table below adjustments are possible to suit varying site conditions.
