The Site

Watch Tower House is an outdated large 1950s office and manufacturing building with no particular architectural interest which does not contribute to the Mill Hill Conversation Area it sits in.

The site is made up of a central building with several wings, a number of outbuildings, tarmac, concrete service roads and carparks.

The site has a dense perimeter of boundary trees which largely screen the site from its surroundings. The existing building on the site is called Watch Tower House, previously the home to International Bible Student Association (Jehovah’s Witnesses).

Emerging Masterplan

Emerging masterplan


The setting in this beautiful part of north London is obviously a huge part of the draw and the proposed masterplan will reflect that, creating homes and spaces that sit sensitively within their green surroundings and existing trees on site.

Our current plans are for a series of two to five storey buildings, as shown in the early Masterplan below. The five storey buildings will be concentrated towards the centre of the site, with four storey buildings will be located closer to the edges of the site and two or three stories closer to the Ridgeway. At present we are aiming to deliver around 180 new homes across the site.

Our vision is for the community to be based around a central square, concentrated towards the north of the site, and pulled away from the site boundaries.

We will seek to reduce the large existing areas of hard landscaping currently used for car parking, to better integrate development into the wider landscape.


Affordable housing to be provided

Proposed amenities for the local community, such as a farmhouse café and shop and a dog day care facility

As the operator, Marstead Living are committed to being a long-term neighbour of the Mill Hill community

Retention of the majority of trees in and around the perimeter of the site and extensive new planting to retain and enhance its character and provide a natural buffer to its surroundings

New senior living homes meeting the significant identified need for such housing in Mill Hill and Barnet

Reducing pressure on local services, compared to a normal market housing developments
