About SB Ewbank



My interest in Stonehenge was sparked by a small personal challenge.

In February 2015 curiosity moved me to examine the ruins of Stonehenge for indications of pattern and design that might answer the mystery of it’s original purpose.

I considered it likely Stonehenge was once a building.

Qualifications:  BSc (hons), DipLA in Landscape Architecture, 30 years experience in landscape design and consultancy,
With experience in planning, landscape and structural design, building, stonework, carpentry and quantity surveying.

Plans, sketches and model are by SB Ewbank.
Research plans presented are based on a detailed measured survey of Stonehenge, by Johnson et al, 2008.
While archaeological excavations reveal in detail what lies beneath the ground, they fail to address the question of what else existed alongside the stones. We know today’s Stonehenge  is  the remnants of a complete circle, the ruined remains of a glorious form, yet little consideration has addressed, why this particular layout, why this design.
What began as a small personal interest project rapidly expanded into two major new theories about Stonehenge’s original form and purpose and revealed Stonehenge’s original unit of measurement.
Research methodology uses existing and derived patterns with geometry in combination with a sound knowledge of building structure. Patterns indicate how features were planned and set out, they generate clues as to what else existed. The basic method used is not new or unknown. Archaeologists examine remains to seek clues as form, pattern and layout. That Stonehenge once existed as a full-circle of capped stones is not disputed, and is indicated as much by pattern, as solid physical evidence.

When born I knew nothing, in a lifetime we continually learn. My experience might parallel that of a Bronze-age designer. A life-time of learning from those already competent, combined with experimentation, would generate more than sufficient skill to think and bring to life everything proposes on these pages.

Bare this in mind – if the Bronze-age people could quarry, shape, move and erect 75 massive sarsen stones, they were very capable: nothing proposed on these pages is as challenging.

Stonehenge was built to plan.

Three Circles set out Stonehenge.

Observe that two pairs of trilithons are set to arcs. The size of these circles is about the same as the sarsen circle.

A centre-point and radius length are essential information used to set out a curved feature.

That similar information was relayed from Stonehenge’s designer to it’s builders, to physically locate these trilithon arcs, is logical.

The location of these red-circle centre-points is not  random.

Three Circles hold two triangles.

Within the arcs are two perfect or equilateral triangles. The arcs cut the solstice axis on the blue-stone circle (south-west) and sarsen circle (north-east). Within the arcs are two perfect or equilateral triangles, (FFA and FFC)

This give seven fixed points:

  • four are where the axis intersects the sarsen (A,B) and blue-stone circles (C),
  • two are the triangle centers (D),
  • and Stonehenge’s centre-point, (E).

Here’s is how Stonehenge was set out. The original unit of measurement will be know as a baunt (Bronze- Age UNiT). A baunt is approx. 1.037metres, about a pace.

Stonehenge was built to plan. It’s unit of measurement is the baunt.


Inside Stonehenge.

How Stonehenge’s roof looked.


Was Stonehenge built as a monument  …or is it the  skeletal remains of a Bronze-age building?

Stonehenge had a roof.                                                                                                  Photo SB Ewbank

Would our ancestors quarry, shape and move such massive sarsen stones, stand them up and stand outside?

In England  4000 years ago it was rainy and cold in winter!

Evidence of the form of Stonehenge’s roof can be deduced by the height and layout of the stones.
