We are thrilled with our kitchen extension - it has completely changed the way we live in our house! The kitchen is now the heart of the home and the formerly unused dining room has been transformed to a sitting area overlooking the garden. Katie took our initial ideas but suggested so many improvements (swapping the kitchen and dining room, adding a window seat in the kitchen, raising the patio to the same level as the house) which ultimately gave us so much more than we ever hoped for. The visualisations really helped us to envision the new space. It was a pleasure to work with Katie and Chris

We have recently completed a knock-down rebuild project on our family home in Wargrave, Berkshire with Chris and Katie at Fineline Architects. We are absolutely thrilled with the project and cannot recommend them highly enough. Fineline supported us with the initial concept designs and selection, planning approvals, costings, tendering and selection of builder, project and contract management, right the way through to the administrative close-out of essential paperwork. Their professional and personal qualities have been absolutely outstanding throughout this multi-year project. Holding our hand
