Principal Designer Services
Most projects require a Principal Designer under CDM 2015 and Building Regulations. We take on this role to plan and coordinate health and safety during the design stage, ensuring risks are identified early and designed out.
This includes managing design‑related safety, coordinating consultants, and preparing essential documentation.
It protects you legally, supports safer construction, and helps ensure low‑energy details - such as airtightness and insulation continuity - are installed correctly and safely.

Our goal is to create better buildings - ones that use less energy, last longer and feel effortless to live in.

HERE’S WHAT OUR CLIENTS HAVE TO SAY
After being sorely let down by another local architect we asked Artis Architects to step in and take on the architectural design for a kitchen and WC single storey extension at the rear of our house. From the start Sheena proved very professional listening attentively to our requirement, answering questions and providing constructive suggestions. She produced three initial drawings very promptly including a wild card outside the brief which we decided to take forward. Final drawings were produced progressively as we developed the detailed plans.
Sheena also handled the approvals and liaised with the Engineer for the structural specifications, with aplomb. During the building she was quick to answer further questions as they arose.
We have been very happy with Artis Architects who are a pleasure to work with. Sheena is very professional and patient, communicates clearly and produces results promptly. We are very pleased with the end result and would not hesitate to recommend Artis Architects.

HERE’S WHAT OUR CLIENTS HAVE TO SAY
Artis architects interpreted our requirements beautifully. The layout has been carefully thought out and they have incorporated all the aspects we were looking for whilst adding some striking design features. Their attention to detail has been very impressive and we are convinced that without their help and experience we would not have managed to get the result we have achieved. They took control of all the approvals and also liaised with the Engineer for the structural specifications.
We couldn't be happier with the end result and for their help throughout our renovation.

We used Artis Architects to redesign the ground floor of our house. We were amazed by the work done and are very pleased with the spacious modern design.
