The company

From day one, we have been driven by a clear vision: to transform the way people think about new-build developments.

Over 20 years later, that ethos is still very much alive, reflected in our numerous awards and enviable reputation in the sector. Today, we employ close to 250 people and has a forecasted revenue of £219 million in 2023/24.

An infrastructure-led community creator and strategic land promoter, we are committed to partnerships, innovation and creating amazing places to live and work. We are industry-leading in sustainability and biodiversity, and all our homes will be net zero carbon by 2025.

We pride ourselves on our ‘infrastructure first’ approach, ensuring communities release the benefits of new development at the outset, rather than later in the process. We deliver social, affordable and retirement housing for a wide range of housing associations and local authorities.

People are our most important asset, and this is reflected in the way we operate. We were recognised in the prestigious ‘Best Places to Work 2023’ and are listed in the Top 100 Best Large Companies to Work For 2023.

Our people enjoy excellent rewards and working conditions in an exciting and growing business. We offer exciting career opportunities, and are keen to develop, guide and support our employees, regardless of what stage they are in their careers. We value diversity and encourage people to bring their full authentic selves to work. A Gold Armed Forces Covenant signatory and supporter of armed force’s charity Building Heroes, we operate a Talent for Development outreach campaign for military veterans and college leavers.

Work and fun should not be mutually exclusive and we offer a range of social events including quiz nights, BBQs and all staff parties. We run informal lunch and learns and take on charity challenges such as dragon boat racing. We encourage people to volunteer in their communities, offering two paid days per year to do so. Where roles allow, our summer hours policy in June, July and August allows people to enjoy longer weekends with their loved ones. A flexible approach to working is available all year round.

Join our team and let’s build communities, together.
