As the original architect for Welwyn Garden City and a 100 year legacy, we have considerable experience in designing new houses, extending existing houses to suit modern lifestyles, and converting older buildings to residential use.

We spend time understanding a client’s needs to translate these dreams into reality. Our service includes carrying out initial consultations and preparing feasibility sketches. We obtain Planning Permissions and Listed Building Consents, submit Building Regulations applications, obtain tenders, and inspect construction works on site.
