Description

An exceptionally rare opportunity to create a one-of-a-kind residence within a historic walled garden estate in the heart of Hertfordshire’s rolling countryside. With full planning permission now secured, this site offers the chance to bring to life an extraordinary home that blends heritage, modern design, and sustainable innovation.

The Setting

The property lies within a registered park and garden, adjacent to a distinguished Grade II* listed house. Enclosed by historic walls and surrounded by sweeping rural views, the site offers both privacy and character in abundance.

The Vision

Designed by award-winning architects MAW, the approved scheme reimagines the walled garden as a modern country estate of architectural distinction. The design balances refined family living with leisure and wellness, creating a legacy home unlike any other in the region.

The Approved Design

Main Residence – A six-bedroom home with expansive living, dining, kitchen, and study areas, carefully designed for family life and large-scale entertaining.

Leisure Pavilion – A private retreat featuring an indoor swimming pool, gym, yoga studio, cinema, and secure below-ground parking for a luxury car collection.

Sustainability at its Core – Planned to meet RIBA 2030 Climate Challenge standards, with ultra-low energy systems, ground source heat pumps, photovoltaic panels, and a biodiverse green roof seeded with native wildflowers.

Materiality & Craft

The approved palette includes charred timber, handmade brick, and natural finishes—creating a residence that is both sculptural and sensitive to its historic landscape.

A Unique Opportunity

This is not just a site—it is the chance to realise a landmark country home, blending timeless design with cutting-edge sustainability.
