Kitchen Extension – Cornwall
A bright, modern kitchen extension featuring full-width glazing overlooking the Cornish landscape. This project includes an open-plan layout with a central island, skylight for natural light, and seamless indoor–outdoor flow through large sliding doors. Designed to increase space, light, and functionality while complementing the existing home.

Full House Renovation
A complete internal renovation involving the strip-out of existing finishes, installation of new stud walls, and preparation for updated electrics, plumbing, and insulation. This stage of the project shows the home being rebuilt from the inside out — exposing floor joists, installing new timber framing, and reshaping rooms to create a modern, efficient layout ready for first fix.
