Listed building architects

Listed building architects specialising in contemporary interventions

We are a leading firm of listed building architects specialising in contemporary interventions.

Our clients come to us because we remodel and extend their listed homes sensitively, while bringing them right up-to-date.

For listed building extensions, our preferred approach is to use contrasting modern architectural design that enhances your exiting listed home.

This type of modern, contemporary remodelling or extension generally requires a minimum construction budget of £250,000 plus VAT.

With a minimum construction budget of £250,000 plus VAT, we can consider all aspects of your building project in detail, apply all our skills and deliver something really special for you.

We’ve worked on many different types of listed homes, from manor houses to farmhouses and cottages. Many of these homes are in conservation areas or in Areas of Outstanding Natural Beauty.

We have particular skills and experience in gaining planning permission for substantial extensions and other works to listed properties.

If you choose us as your partner, we will challenge, inspire and delight you. We will take time to inform you, collaborate with you and then deliver an imaginative, beautiful home.

We work across the south of England and our multi-disciplinary team of professionals is ready to help bring your listed home to life.

William Green started the practice in 2007 and is still very much hands-on in all our projects. He passionately believes that adventurous architecture can be liberating and enriching.

Alongside architecture and planning services, we offer interior and landscape design services and contract administration.
