Cornish developers with 30+ years experience



Built and sold



Expressions of interest being accepted from January 2022

Fancy waking up to your own game of thrones castle everyday?

Yes, Olivia Cooke, Matt Smith and Emma D'Arcy were actually seen here during April 2021 when the Game of Thrones prequel 'House of the Dragon' started filming.

These large properties (300m2 internal floor area) will be the most environmentally friendly of our portfolio to date.

Set in an area of Outstanding Natural Beauty, their designs maximise the coastal position while achieving a low visual impact. Construction will use a highly insulated envelope, incorporate solar energy with battery storage technology to power the heating, hot water and electric car charging systems.

Heat recovery systems will keep energy use for heating to a minimum, whilst ensuring a continuous flow of filtered fresh air into the house. Sedum roofs will enhance the thermal performance of the building which has the added benefit of encouraging local fauna to proliferate and soften the roof lines. Set out over four floors, each house has stunning views of the iconic St Michaels Mount and Mounts Bay.

High quality fixtures and fittings, statement staircases and lighting, home cinema rooms and hot tubs, give these houses the opportunity for luxury living. All houses will have garden offices to allow for interruption free working from home. As you would expect, all properties will have 10-year structural warranties and a two year snagging period, personally overseen and administered by the developers.

PRICES from £2m+, available Spring 2023. Expressions of interest being accepted from January 2022.

  • If you walk across the causeway to the Mount for your morning coffee, the tides will have actually parted the sea to allow access to your latte! Surely better than Starbucks in the high street?


  • Followed by some essentials shopping in beautiful Marazion village on the way back.


  • Before walking home to do a spot of work in your office, followed by lunch on the balcony, looking out to sea.
