Turning houses into homes: your journey with Stonehouse Interior & Lighting Design

“Simplicity, suitability and proportion"

Elsie de Wolfe

We now offer comprehensive design solutions from concept to completion

For the past 25 years, we've had the privilege of helping homeowners bring their dreams to life. What began as project management and cost consultancy in construction has evolved into a fully integrated interior design journey - seamlessly combining our expertise in MEP design and cost consulting to turn your vision into reality.

We realised our clients needed more than just project management; they wanted a trusted partner to guide them through every step of creating their perfect home. That’s why we now offer a complete service - from concept and space planning, and full project coordination during construction, to selecting the perfect sofa and ensuring your lighting sets the ideal ambience.

“If you want a golden rule that will fit everything, this is it: Have nothing in your house that you do not know to be useful or believe to be beautiful."

William Morris

Meet Maria

Maria Cooper

Remember that friend who always had an eye for beautiful spaces? That’s Maria - an Interior Designer who holds a law degree, a Master's in Real Estate Appraisal, and a Diploma in Interior Design. With over 15 years of hands-on experience delivering high-end residential projects from conception to completion, she is comfortable with both technical and creative language. Her passion is helping people create spaces that tell their story, armed with both practical construction knowledge and a sound understanding of legal contracts. Her unique edge lies in her ability to enhance the value of a project and work closely with the team at Stonehouse to provide robust design costs and layouts developed alongside the MEP design team, avoiding unnecessary risks for the client. She designs spaces that deliver both functionally and aesthetically. Maria brings both expertise and heart to every project.

“Be faithful to your own taste, because nothing you really love is ever out of style."

Private Client

Mrs Hirst

I highly recommend Maria Cooper, who led the full renovation of my home with exceptional creativity and professionalism. She reimagined the layout into a bright, open-plan living space and delivered thoughtful lighting and electrical design, sourcing both architectural and decorative fittings.

She designed and installed a beautiful, functional kitchen, reconfigured a media room, and managed design and procurement of finishes and custom doors. She coordinated all trades and suppliers seamlessly, delivering high-quality results within a budget.

Her attention to detail and ability to balance design with practicality were outstanding.
