Whether you are planning a bespoke new-build house, transforming an existing property or considering a contemporary extension, we combine creative architectural design with practical experience to unlock the potential of your home or site.

From our Cheltenham practice, we can guide you through the entire architectural process — from initial ideas and feasibility through planning permission, technical design and construction.

Residential Architects in Cheltenham & the Cotswolds

Every successful home starts with understanding how you want to live.

We take time to understand your ambitions, your property and its surroundings before developing a design. Our architecture is contemporary and distinctive, but always considered in relation to its context.

Working throughout Cheltenham, the Cotswolds, Gloucestershire and surrounding areas, we specialise in residential projects where good design can make a meaningful difference to the way a home looks, feels and functions.

New-Build Homes

Bespoke architecture designed around you and your site

Building a new home offers an opportunity to create something genuinely individual.

We design bespoke new-build houses that combine architectural ambition with an understanding of landscape, planning, materials, daylight and energy performance.

From assessing the potential of a site to developing the concept, securing planning permission and producing detailed construction information, we can guide you through each stage of creating your new home.

House Extensions & Renovations

Transforming existing homes through considered design

A successful extension should do more than simply add space.

We look at how your entire home can work better — improving natural light, views, circulation and the relationship between existing and new spaces.

Whether you are considering a contemporary kitchen extension, a substantial renovation or the complete transformation of an existing house, our aim is to create architecture that feels coherent, purposeful and beautifully resolved.

Contemporary Cotswold Architecture

Designing within the Cotswolds requires a sensitive understanding of place.

The area’s distinctive villages, landscapes and historic buildings create both opportunities and constraints for contemporary architecture. We believe new architecture can complement its surroundings without simply imitating the past.

Through careful consideration of scale, proportion, materials, views and landscape, we create contemporary homes that respond confidently and sensitively to their Cotswold setting.

Planning Permission & Architectural Services

Taking a building project from an initial idea to a completed home involves many decisions.

As RIBA Chartered Architects, we can provide architectural services throughout the project, helping you navigate design, planning and construction with a clear and structured process.

Our services include:

Consultation & Feasibility
We explore your brief, budget, property or site and identify opportunities and potential constraints before significant design work begins.

Concept Design
We develop architectural ideas around your requirements and explore how space, light, materials and the surrounding context can shape the project.

Planning Applications
We prepare and coordinate the architectural information required for your planning application and manage the submission through the planning process.

Technical Design
Once planning permission is secured, we develop the detailed architectural information required to turn the approved design into a buildable project.

Construction Support
We can continue to work with you, your contractor and the wider consultant team during construction, helping maintain the quality and integrity of the design as it becomes a reality.

Why Choose Lewis Critchley Architects?

We believe good architecture comes from a combination of creativity, experience and collaboration.

As a RIBA Chartered architectural practice, we bring professional expertise to every stage while maintaining a personal, design-led approach.

Our work is characterised by careful attention to proportion, daylight, views, materials and detail. Rather than imposing a predetermined architectural style, we develop each project around the client, the property and its setting.

The result is architecture designed not simply to look impressive, but to be enjoyable to live in for many years to come.

Architecture From Concept to Completion

Our architectural process is designed to make creating or transforming your home as clear and enjoyable as possible.

We work collaboratively with our clients from the earliest conversations, helping establish what is achievable before developing the architectural concept and guiding the project through planning and detailed design.

Where required, we can also work alongside structural engineers, planning consultants, landscape designers, contractors and other specialists to help coordinate the wider project team.
