Welcome to the Treetops at Hesslewood Office Park

Nestled within the scenic landscape of Hesslewood Office Park, the Treetops development stands as a testament to innovative design and sustainability. Now complete, let’s delve into the story of this remarkable project and uncover its unique features.

Design Inspiration

The design concept for Treetops was born from the creative minds of Peter Barbor, Chairman of Brooklands Property Holdings, and Debbie Barbor, CEO of Brooklands Property Holdings. They envisioned transforming an underutilised area of the office park into something exceptional, and while on holiday they drew inspiration from treehouse-style buildings; the concept seeming perfect for accommodating the site's varying elevations, offering level access to main entrances and providing breath-taking views across the parkland.

Construction Timeline

The build journey for the site of the Treetops began with the excavation and pouring of footings in August 2021. Soon after, in April 2022, the steelwork started taking shape, followed by the construction of timber frames in June 2022. It was at this point that the development really came to life, visually, with the concept no longer being an idea in the mind or a computer generated image. By October 2022, the interior fit-out was in full swing and - such was the buzz around the innovation of the project - all 5 pods were pre-let in advance of completion. The Treetops welcomed the first of those tenants in January 2023 and the remaining occupiers where soon to follow. The balconies, completed in August 2023, have been the final touch on the pods with the decision to use glass balustrades being a multifaceted one of sustainability, aesthetics and practical use. Avoiding the use of non-renewable materials for the main balustrades, aligned with the commitment to sustainable design. Additionally, the use of glass means that those stunning views of Hesslewood's parkland remain uninterrupted, whilst playing to each pod's contemporary and minimalist aesthetic, externally.

Harmonising with nature

As of now, the Treetops development is complete, offering a distinct and eco-friendly addition to Hesslewood Office Park. All five Treetop pods share a consistent construction specification, though their heights above ground differ to harmonize with the natural terrain. The tallest pod reaches a height of 3.2 meters above ground. Interior fit-outs maintain a high standard, featuring uniform bathrooms and interior finishes.

Notable Features

There are several noteworthy aspects of Treetops:

Integration with Nature - each pod harmoniously coexists with the existing trees - even built into the balconies - preserving healthy specimens to envelop the pods and create an enchanting "treehouse" ambiance.

Energy Efficiency - according to PropertyInvestment.Com the UK’s built environment is responsible for 25% of the country’s carbon emissions. In a demonstrable move to reducing carbon footprint, the pods have been meticulously designed to maximize energy efficiency and boast an impressive A rating for Energy Performance Certificates (EPC).

Sustainable Cladding - as commercial developments move towards a more sustainable future, Hesslewood continues to push forward in the commitment to eco-friendly construction by having sourced sustainable timber, for the crafting of each pod’s exterior cladding and using renewable materials wherever possible.

Innovative Construction - the Treetops stands out for its innovative and experimental construction methods, making it a rare gem in the UK's architectural landscape. The cluster of five pods, each spanning 500 square feet, offers a unique office space solution.

Local Involvement - contributing the growth and prosperity of the region is an important factor for the developments at Hesslewood Office Park. The realisation of the pods - from concept to completion - is testimony to that commitment, with local architects, engineers, manufacturers, suppliers, and tradespeople from the region having played a pivotal role in bringing Treetops to life.

The whole project involved a careful team of collaborators, and special mentions go out to:


Chris Kendall - Town Planning Consultant and partner at Hickling Gray Associates has, since 1993, successfully managed the complex planning applications for various projects at the office park. Taking into account the environmental, sustainable, and conservation aspects of the site, Steve worked closely with the architect, Jonathan, and the structural engineers, Griffin Toombs, to ensure that the Treetops development is respectful of the natural surroundings and meets the needs and expectations of the clients and the community.


Ingleby Hobson - the architectural firm that has supported Hesslewood Office Park since its inception in 1993. Jonathan Hobson, a talented and visionary architect, has transformed the site into a vibrant business hub that hosts 31 companies and 800 people from both local and global markets. Jonathan has seamlessly integrated the new buildings with the 17th century setting, incorporating stunning Humber views and focal points, and reviving a neglected 17th century Game larder into a lively café delicatessen. He has also optimised the new offices for natural light and scenic views of the river, using modern open plan layouts. Jonathan’s sympathetic flair has resulted in the fun and functional, respecting the historical context, and showcasing his creativity and innovation in the Treetops project, which offers office space that meets the demands of the 21st century. The site overall, now boasts 120000 sq ft of contemporary grade A office space.



Griffin Toombs Civil and Structural Consulting Engineers - with over 40 years experience, with Steve Griffin and his team having worked on various projects for us at Hesslewood Office Park, including the Treetops. Always embracing the challenge of turning Jonathan’s concepts into reality, and using their expertise and creativity to ensure structural integrity and aesthetic appeal - The Temple, which serves as both a striking landmark at Hesslewood Office Park and as a gym facility for the site, being another celebrated example.


EYG Commercial - East Yorkshire Aluminium and Glass Ltd, were involved in the glazing of the development. We were delighted to hear news, in March 2024, that EYGs commercial division were named the winners of a prestigious national award which recognises excellence in the glazing sector. The awards are ran by Glass and Glazing magazine, recognising the best installations and projects across the UK. In EYG Commercial’s pre-awards blog, Nick Ward, managing director of EYG Group, said: “These treehouses are unique, we’ve never glazed anything quite like these before, and although you might see designs like this in the hospitality sector, I imagine they’re highly unusual in the commercial offices sector. The team were the proud winners of the ‘Best Commercial Installation’ award at the Glass and Glazing Products (GGP) magazine’s Installer Awards 2024, for their work on the development.

Dr James Britton of Ozone Health, explains a little about their business, saying "Our business is in healthcare with the development and maintenance of digital health platforms, providing tele dermatology and telemedicine services and also the platform to run all aspects of clinics and consultations."

When asked what attracted Ozone Health to the Treetops development, Dr Britton said "We were attracted to the treetops because it was a new development, so we could influence design. It was the right time for expansion with landlords that we know and trust to grow our business. The attention to detail of the design with the unique raised elevation of the offices within the trees giving amazing views good we knew would make these a unique office experience. We knew that this would get the best out of our team with them working in such an amazing environment."
