Thoughtful Alterations Designed Around Your Home

Altering your home is an opportunity to improve how it looks, feels and functions without starting from scratch. At ARP Architects, we specialise in carefully considered alterations that enhance existing buildings while respecting their original character.

As a RIBA chartered, Exeter-based Architect, we work closely with you to reimagine your space, whether that means opening up interiors, improving natural light, reconfiguring layouts, or making significant structural changes.

Every alteration project is tailored to your lifestyle and the unique qualities of your property.

Our customers say

We engaged Andrew to work on the plans for our extension and we would have no hesitation in recommending him. Andrew is very easy to work with, he listens well and presents easy to understand options to help you move forwards.

He helped us on some design decisions, solved technical challenges that our desired roof design presented and after submitting the plans, went on to work very well with the builders when any minor problems occurred during the build. The result is an amazing space, even better than we dared to hope for, and Andrew certainly played his part as a crucial member of the team that achieved that.

Paul Berman

Andrew listened carefully to our requirements/objectives and designed, planned and co-ordinated the conversion of our rather confused 1940s house with antisocial individual rooms into a generous open flowing living space making it a much more flexible, sociable family home.

Andrew was a pleasure to work with, and I loved his attention to detail. He worked very calmly with the builders, bathroom and kitchen fitters and I would thoroughly recommend Andrew to anyone looking for an architect. I now love my house after 23 years of living here and wanting to move!

Nicola Day

Andrew took a professional and constructive approach throughout the whole process. He took on board our ideas and came up with a design that could be done in two stages to meet our needs. From initial design ideas to structural engineers, to build issues through to completion, Andrew was on hand to support us and our builders.

He took the project through the planning process for us, which was of enormous help in what otherwise could have been a far more stressful experience because we had never attempted a project like this before. We would have no hesitation in recommending his services to others. The finished design has exceeded our expectations and transformed the way we live in our home. Thank you Andrew

Our Alterations Design Process

Making changes to an existing building requires careful planning and expertise. As your local Alterations Architect in Exeter, we guide you through every stage, including:

  • An initial consultation to understand your goals and assess feasibility.
  • Creative design development to maximise space, light, and flow.
  • Structural coordination for wall removals, layout changes, or basement works.
  • Preparation of detailed technical drawings and specifications.
  • Support through planning permission, listed building consent, and building regulations approval.

We act as your single point of contact throughout the design process, coordinating with structural engineers, consultants, and contractors to ensure everything runs smoothly.

Start with an Initial Consultation

Every alteration project begins with a conversation. ARP Architects offers an initial consultation to explore the potential within your existing space.

As an experienced Exeter-based Alterations Architect, we bring design insight and technical knowledge to help you understand what’s achievable. We specialise in identifying opportunities you may not have considered and offer solutions that balance practicality with creativity.

Planning Permission & Listed Building Consent

Alterations can sometimes require planning permission, particularly if your property is listed, located in a conservation area, or if your project involves significant structural changes.

We have experience working with sensitive and heritage properties across Devon, carefully preparing project applications that respect architectural character while meeting modern living requirements. From planning submissions to building regulations compliance, we manage the process on your behalf, ensuring clarity and confidence at every stage.
