The Old Mill

Contemporary Extension linking a Group of Listed Buildings.
Location Milford On Sea, Hampshire
Status Under Construction
Use Residential
Client Private

A modern rebuild linking and restoring a group of Grade II Listed, ruined buildings in the New Forest, Hampshire to bring them back into use as a family home.

This unique oasis within the heart of Milford on Sea was overgrown, its waterways silted up and land flooded. The three buildings on site include the Old Mill, a significant historic 18th century water mill. The Mill House had been destroyed by fire and the rest of the buildings were badly vandalised and neglected. Our clients bought the site in 2016 and the designs to restore, renovate and extend the group of ruined listed buildings began.

Local support

Due to the site being in a Conservation Area, in a flood zone and including three Grade II listed buildings, this project went through extensive Pre-Application discussions with New Forest District Planning Authority.

The site’s importance, overwhelming support by neighbours and a well-attended presentation by WDA, helped us gain approval of our application at planning committee in 2018.

Reflecting the site’s historic layout

The design consists mostly of a glazed extension linking the three historic buildings to form one dwelling. The new extension was designed to contrast in style and materials to the existing buildings. Our landscape concept design was based on historic mapping and old footpaths through the site.

The remaining group of three buildings was once a group of five in the 1890’s. This original grouping is reflected within the design of the new extension, through two slightly raised roof elements which signify the original location and size of the historic buildings.

Panoramic garden views

To allow as much transparency as possible within the new extension, the more private rooms such as bedrooms are housed within the walls of the existing buildings. This leaves the new element as mostly open plan living space with panoramic views into the garden and mill stream. The individual pieces of glass were the largest we have ever designed. One piece alone cost £22,000.


In October 2021, The old mill featured on Channel 4’s Extraordinary Extension hosted by Tinie Tempah. Our self-builder clients had been approached by a couple of other TV shows, but this one was particularly appealing to them as it focuses on extensions.
