Roehampton House

Roehampton House

Project brief

Tarmac Building Products were asked to supply Queen Mary’s development (a historic London hospital converted into apartments) with Tarmac Heritage Hydraulic Lime Mortars.

The Project

The project ‘s aim is to convert Grade I Baroque stately home Roehampton House into residential use with a mix of old and modern construction materials. Roehampton House is a Grade I Baroque Stately Home built by Thomas Archer over the years 1710-12 and later enlarged by Sir Edwin Lutyens in 1910. The house is being carefully restored, maintaining its original features both internally and externally, with Doric columns and wrought iron railings giving way to panelled walls, ornate painted ceilings and black and white marble.

Help from Tarmac Building Products – Heritage Hydraulic Lime Mortars

We supplied Tarmac Heritage Hydraulic Lime Mortars in mobile dry silos to the large-scale heritage site in Roehampton, south-west London. The product is predominantly a bedding masonry mortar but due to its versatility, can be used in other areas and is ideal for projects such as this one because it is a cement-free traditional product and so recreates an appearance in keeping with the history of the building. It is being supplied alongside natural and Y101 white mortar in dry silos.

Problems faced

The former hospital developed into a stately home is a Grade I listed building, meaning that any new building work needs to blend in well with the existing building work. Grade I buildings are of exceptional interest, sometimes considered to be internationally important; only 2.5% of listed buildings are Grade I.

The project site is located within Flood Zone 1 and so a Flood Risk Assessment is required as the site is over 1 hectare.


Roehampton House, its two gate houses and the remainder of the Roehampton Estate are being redeveloped to provide luxury new housing. The development is called Queen Mary’s Place. Of the original 30 acres, only 14 remained following the building of the new hospital, but the developer, St. James has preserved 30% of the land for pleasure gardens for the new residents.

The Grade II listed sunken and rose gardens have also been lovingly restored to provide the perfect setting for the newly created 1, 2 and 3 bedroom apartments and two 2 bedroom gate houses.
