About Us


We are a multi-sector property company specialising in the development of new build affordable homes, mainly in the Dorset and Hampshire areas.

The company are also residential and commercial landlords with properties let across the country, ranging from studio apartments, flats, houses and office blocks to a 16 bedroom HMO (House of multiple occupancies).

Our business is to research, identify and purchase suitable properties and to create inspirational plans to fulfil the needs of the area and community they will serve.

We do this by purchasing, renovating or converting existing properties to rent or by designing and building new houses, bungalows or flats to sell.
