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.

Kirsty Keenes

Kirsty is our Office Manager. Growing up in Poole she went on to spend 3 years in Dorchester and the surrounding areas whilst studying at Kingston Maurward College to fulfil her interest in agricultural and rural business studies.

After qualifying, Kirsty moved to the Cotswolds to PA for private families and their businesses. Kirsty met her husband Michael and together they have self built their own rural home, which acts as the perfect base for walking their dogs and is conveniently close to a golf course. Kirsty took up golf in 2019 to be able to spend more time with Michael (a keen golfer and at his prompting) and is now a competitive member of the ladies section at Feldon Valley GC.

When not working and researching, walking or playing golf, Kirsty will likely be found riding – her lifelong passion for horses continues and Kirsty is a competent rider.
