From Bungalow to Beautiful: A Smart Second-Storey for a Growing Family

I helped this family turn their modest bungalow into a spacious, modern home - A full second-storey added generous bedrooms, a home office, en-suite, and balcony. Room to grow, work, and breathe.

Old Soul, New Space: A Two-Storey Cottage Extension Designed for Light and Life

A two-storey extension brought together the charm of a traditional country cottage with the space and brightness a modern family needs. Thoughtful window placement and a sun tunnel brought in natural light, while a mix of exposed stone and clean finishes helped to balance old and new. Love your cottage but wish it was bigger? I can make that work.

Blending Old & New: A Characterful Barn Conversion and Extension

This barn transformation celebrates the beauty of local craftsmanship and rural character. The new timber-clad extension sits in harmony with the granite and oak of the original barn, linked by a light-filled space that brings the two buildings together. This project is a great example of how sensitive, well-planned design can breathe new life into traditional buildings while enhancing how a home works day to day.

A Home That Fits Just Right: A Modest Extension

A modest extension created space to reposition the dining area and improve the flow of this home.
By matching the roof pitch to the existing house, the extension feels like it was always part of the design. Proof that even small projects can make a big difference to everyday living.
Thinking of a smaller project? Even subtle changes can transform how you use your home.

Bright & Flexible Living: Rear Extension and Internal Redesign

A bright new kitchen-dining space with a lantern roof light, improved layout, and a flexible ground floor bedroom - perfect for guests or letting. Small changes can have a big impact on how you live every day.

Upward Thinking: A Loft Conversion with Style & Space

This loft conversion added a spacious main bedroom with en-suite and a first-floor office. Creative roof design and well-placed windows brought in light and interest, while the new staircase was carefully planned to flow with the existing home. A loft conversion can add both beauty and value to your home.

Rosie helped us turn our dreams into reality and supported us with turning our vision into a functional living space. From the outset, Rosie had some great ideas and demonstrable expertise in her field. She came up with some great ideas that we would never have thought of. Communication was clear all the way through the project stages. I wouldn't hesitate to use Rosie Stokes Design again in the future.
