Building specifications: The construction of new 65,000 sq ft industrial/manufacturing unit with offices and staff facilities on a 4.54 acre site. The building has a clear height to underside of haunch of 8.0m. External site works comprise hardstanding/yard areas, car and van parking, and landscaping and drainage.

The first phase of 65,000 sq ft Grade A factory and production space at the Building 6000 development was let on a 10-year lease to Green Retreats.

The development achieved a BREEAM ‘very good’ rating and particular attention was paid to the reduction of embedded carbon within the construction process.

The project team included Parkway Construction MK Ltd working alongside McCurdy Russell Architects, Civil and Structural Engineering Consultants HDR Bradbrook Consulting, Building Services Engineering Consultants Shepherd Brombley Partnership and Health and Safety Consultants Building and Workplace Solutions Limited to deliver the project.

Green Retreats is the largest, leading and most trusted garden room company in the UK and has been based at Westcott for the last eight years, now occupying a total of 115,000 sq ft of space at the park. 

The company currently employs 330 staff, and this new facility will enable Green Retreats to scale this up to 580 employees and will provide the additional capacity to increase turnover from £35million to £70 million for Phase 1 of the development.

We have enjoyed significant growth and our new facility will provide us with the space to expand in order to realise our full potential. One of the reasons we chose to base the business at Westcott was because of the room for expansion, we have expanded three or four times and each time the Park has been able to accommodate our growth. It’s also a highly secure site and our customers enjoy the experience of coming to Westcott to visit our showroom. As a carbon neutral business, we value the benefits of the solar park and we work with many service businesses on the Park. We feel good about the future and being part of the Westcott family of companies.

Green Retreats managing director, Roy Wetherall

From the very beginning, our close relationship with Green Retreats ensured that we and our contractor Parkway understood their specific requirements and could complete the development successfully within the agreed timescale and budget despite the very challenging conditions being experienced in the construction industry currently. This is our largest new development scheme to date at Westcott and it is a superb example of the high-quality buildings we can create for occupiers seeking accommodation in the region.
