Completion is an interior design and interior architecture specialist service based in Cheltenham, Gloucestershire and London. Founded in 1999, we pride ourself on being one of the leading private small interior design firms in the industry.

Honest, creative and professional interior and architectural design services

We have a strong ethos in personal service and believe in forging honest and professional relationships with both our clients and local trades.  It is the ability to forge such relationships that has enabled us to deliver our projects so successfully, relationships which often extend beyond the initial commission.

Completion was formed to help create and enhance internal living and functional areas of both private residences and commercial properties such as boutique hotels to benefit the people using that space.

Good interior design is therefore a very personal experience.  Understanding a client’s needs and dreams for their space and translating that into a reality is therefore an intimate process.

Services personal to you and your home

We are experienced in co-ordinating interior design and interior architecture projects from start to finish around your individual lifestyle to provide you with beautiful, stylish spaces you will love to live in.

At the heart of our service lies our passion for creating timeless elegant interiors that are practical and sympathetic to properties and owners alike.

We look forward to hearing from you and helping to transform your property into the home of your dreams.

Gilly & Amanda



Gilly Read

Gilly founded Completion in 1999 after a successful early career as an artist and teacher of art. Her background in art history and textile design led her to apply her talent for creating timeless elegant interiors for herself and close friends.  The combination of talent and passion coupled with the success of her projects led her to re-train as an interior designer and she now applies her time fully to design and project manage beautiful interiors for clients in Gloucestershire and throughout London.


Amanda Fisher

Amanda began her career in the design industry by studying Spatial Design at Falmouth University where she specialised in the remodelling of buildings. On completion of her degree, she went on to begin working within interior design in Cheltenham and has now accomplished many projects of various scales and styles. She joined Gilly in 2014 to continue her passion for creating spaces which are both functional and attractive.
