The Atrium monoprint at The Sherborne is 11metres high and shows the rocks at Kimmeridge Bay which were once the floor of a deep, tropical sea rich in pre-historic life. They were formed in the Jurassic period, 155 million years ago.

As part of his exhibition Turning the Tide, artist Gardiner presents a stunning 11-metre-high monoprint at The Sherborne in Sherborne, Dorset. Inspired by ancient mural traditions seen in museums and historical sites—from Etruscan ceramics to Greek temples—this work pays homage to how civilisations have used walls to tell their stories.
The vertical monoprint depicts Kimmeridge Bay’s rock formations, once the floor of a prehistoric sea. These Jurassic layers, formed 155 million years ago, act like pages of a book, each revealing a chapter of Earth’s geological history.
Reading from top to bottom, the print begins with LiDAR contour patterns etched in steel, followed by a topographic copperplate drawing of Kimmeridge Bay featuring Clavell Tower. In the centre is an ochre slab representing the strata, and at the base, a woodblock print of an Asteroceras ammonite—preserved in rock for over 150 million years.
Gardiner’s work transforms the wall into a window through time, rooted in place and history.






Planning Committee Success
SPASE Design has recently achieved planning success at committee for a new build eco-house replacing a mobile home in the countryside.
The existing mobile home was a converted former railway carriage with a certificate of lawfulness to use as a permanent residence. This offered an unusual opportunity outside of defined development boundaries for replacement with a new build home.
The proposal has been designed as an off-grid dwelling, sensitive to the site and with biodiversity and sustainability in mind. Our clients are passionate about the environment and this scheme will support their desire to live off the land.
The house is designed to appear as a converted barn appropriate to its agricultural setting, providing a significant enhancement from the former railway carriage whilst also offering sustainable and ecological benefits to the site overall.
Concerns were overcome regarding flood risk, sewage treatment and visual impact, and resulted in counsellors voting in favour of approval.

Sarah joins SPASE Design to enhance as a chartered architect with over 20 years of experience specialising in sustainable, low energy design, to enhance the practice’s credentials and expertise in sustainable design.
Sarah has a wealth of technical experience at job running, coordinating design packages and providing site supervision on large scale developments in the education and residential sectors.
In 2015 Sarah embarked on self-building her own family home on the outskirts of Weymouth in Dorset to the Passivhaus standards.
The house is contemporary in style and constructed from a timber frame filled with recycled newspaper for insulation with a zinc roof. Sarah ran the build, managing local sub-contractors, ordering materials and proving detailed drawings.
Sarah says ‘The hardest part of the build was ensuring every single sheet of the airtight membrane was lapped and sealed internally forming a super airtight layer which eventually tested at 0.37ach air changes per hour.’
Since achieving Passivhaus certification with her own home, Sarah supports the national network for low carbon open homes, and Dorset Greener homes by hosting open days to show case self-building and low energy design.
Sarah also takes part in the international Passivhaus open days each year, opening her home to visitors interested in building to the Passivhaus standards.
For the last two years Sarah has been working as project architect on a refurbishment and retrofit school in Wimborne, upgrading a collection of Victorian school buildings into an SEN facility for 13-18 year old students.
Beaucroft College was one of the first projects in Dorset to be awarded government SALIX funding due to the installation of renewable energy including air source heat pump, photovoltaics and heat recovery system along with thermal upgrades to the existing fabric. The retrofit project has been calculated to reduce annual C02 emissions by 76%.
Sarah was thrilled to read in the news recently that the project has been selected as a finalist in the AJ 2024 awards in the retrofit and decarbonisation section.
As an architect Sarah prides herself on the value she brings to both client and site, through sustainable, high quality and efficient building designs.
Sarah says ‘I believe that buildings and places should be designed to encourage healthy lifestyles and help people to reduce their environmental footprint. I design with future generations in mind, aiming to support biodiversity and make the best use of resources. I am looking forward to working with the team at SPASE, where I can integrate my design skills and experience into more zero carbon projects.’
Our work to Sherborne House receives recognition in the Architects’ Journal

Sherborne House, a Grade I-listed building with Georgian, Tudor and Medieval elements, has been restored and extended with a glulam-structured pavilion and event space
The main structure is an early Georgian mansion attributed to local architect-craftsman Benjamin Bastard. It features a mural of hunting scenes up the principal staircase, completed in the late 1720s by Dorset-born artist James Thornhill.
The building, renamed The Sherborne, now has gallery spaces in both the historic rooms and new spaces, with a sculpture garden and external amphitheatre space for live performances at the back. It also accommodates a commercial offering of a bistro and restaurant, event spaces and a shop stocking local products, with profits supporting the arts programme.

This article highlights a fascinating case of retrofitting a historic home

This article highlights a fascinating case of retrofitting a historic home, Athelhampton Manor, with renewable energy technologies. It illustrates how older properties can embrace low-carbon heating solutions, specifically through the installation of modern air-source heat pumps and solar arrays.
Key points include:
- Historic Context: Athelhampton, a Grade I listed Tudor manor, faced high heating costs and an inefficient heating system. The previous reliance on fossil fuels resulted in an annual bill of around £55,000 – more than £100,000 with current energy prices.
- Innovative Solutions: Owner Giles Keating partnered with Stefan Pitman to implement a comprehensive energy overhaul, utilising next-generation air-source heat pumps that offer high efficiency (up to 450%) and integrating solar power with storage batteries.
- Transformative Results: The retrofit drastically reduced energy costs to just £500 in 2023, enabling the manor to remain open year-round. The unobtrusive design of the renewable systems helps maintain the property’s historical aesthetic.
- Broader Impact: This project not only sets a precedent for other historic homes but also demonstrates the feasibility of integrating modern technologies into conservation efforts. Pitman’s firm is now working on similar projects across various historic sites.
- Planning and Collaboration: The article emphasizes the importance of engaging with local authorities early in the planning process to navigate potential regulatory hurdles, positioning these retrofits as examples for others to follow.
