Hi, I’m Daniel Kozinski the founder and Managing Director of DK Building (Liverpool) Ltd and Retrofit People, two businesses united by a shared commitment to exceptional craftsmanship, customer service and sustainable construction.

I have a simple vision: to provide high-quality retrofit building services to discerning residential clients who value reliability, clear communication and outstanding workmanship.  I am supported by a trusted team of skilled professionals who share my uncompromising standards and passion for delivering excellence.

Recognising the growing importance of energy efficiency and sustainable homes, I founded Retrofit People as the sister company to DK Building. Retrofit People focuses on helping homeowners improve the comfort, performance and environmental impact of their properties through expert retrofit solutions, including insulation, heating improvements and whole-house energy efficiency upgrades. I’m passionate about delivering retrofit projects that reduce energy consumption while creating healthier, more comfortable homes.

Today, I continue to lead both businesses with the same hands-on approach that inspired their creation. By combining traditional building skills with modern technology and sustainable construction practices, bespoke projects that stand the test of time.

“We like to think our work speaks for itself.”
