Crafting Spaces,

Building Legacies


Established in 2020 by James Hartt, Hartts Construction has rapidly emerged as a paragon of trust and excellence within Portsmouth and across South-East England. Our story began in a humble 200-square-foot garage, but our vision was always grander. Today, from our 1800-square-foot workshop, we deliver innovative and sustainable construction solutions that set new industry standards.

Our ethos is simple yet ambitious: lead with innovation, build with sustainability, and excel with every project. Pride is taken in not just constructing buildings, but also in crafting the relationships and communities around them. Integrity, transparency, respect, and excellence are cornerstones of our work ethic, laying the foundation for enduring structures and lasting partnerships.


Our commitment to excellence goes beyond our construction sites. It's harmoniously marrying form and function to create something truly extraordinary. 


Discover with Hartts Construction - where your vision, our expertise, and shared values converge to create not just buildings, but legacies.

Client Success Stories:

Hear What Our Clients Say

Undertaking a home renovation is a daunting task, but choosing the right team can make all the difference. Our experience from planning to completion was nothing short of amazing. The team guided us through each phase—making the process less stressful and the outcome spectacular. Our home now boasts beautiful oak chevron flooring, a spacious new extension, and bespoke features like Crittall doors that have transformed our space into something out of a magazine. If you're contemplating a renovation, take it from us—go for it. You won't be disappointed.


Nutbourne, Chichester

In the decade we've worked together, the team has consistently taken our vision for Green Mango Salon and turned it into something extraordinary. From the first redesign to the latest Scandi-chic transformation, their creativity and attention to detail have been unmatched. The oak acoustic wall cladding not only enhances the acoustics but also adds a warmth and elegance that our clients love. The large format mirrors and bespoke front desk are not just functional; they are statement pieces that elevate the entire salon experience. It's a pleasure to work with a team who understands the essence of our brand and brings it to life with such finesse and sophistication.



At Hartts Construction, we aim to disrupt the status quo within the construction sector by simplifying the complex process into digestible, 'Jargon-Free' offerings that our clients can easily understand. Our drive for innovation is matched by our commitment to sustainable practices, ensuring that the visionary needs of our clients are met in ways that benefit both the environment and the community. We place a strong emphasis on precise craftsmanship and eco-friendly methods, ensuring each project is not just remarkable in its execution but also responsible in its impact. This holistic approach to construction ensures that while we're shaping skylines, we're also supporting sustainable living, reflecting our dedication to excellence and to the future of our planet.

Our steadfast commitment ensures that every structure we create is a testament to our dedication to quality, functionality, and aesthetic merit. We endeavour to surpass traditional construction techniques, to create spaces that improve lives, elevate moods, and endure through time.


At Hartts, we don't just construct; we establish new benchmarks for the future of construction.
