We help unlock the power and potential of real estate as a means to support business growth, change and culture.

Always on your side

Here at Reesa, we act as tenant only advisors. Our mission is to help clients feel engaged, happy and motivated through their working environment, to tune into their needs and ambitions, allowing them to be moved both physically and metaphorically into or out of a space.

We ensure that we not only maximise savings, but secure an occupier friendly licence or lease that will protect their interests for the duration of their tenancy.

We believe in long term partnership

At Reesa, we firmly believe in a ‘client for life’ philosophy; not only will we help secure the office most suitable for your organisation, but we’ll be there for you throughout your business expansion and relocations in the future.

No other firm goes as far and wide as our research team to ensure that our clients get the maximum visibility of options available.

Transparency is key to our ethos and the service we provide is always personal and engaging. We are an accomplished team of professionals who work closely with our clients, offering a meticulous approach that is both ambitious and energetic.

Our History

Reesa was established over 5 years ago with the objective of providing our clients with honest and objective advice whilst being viewed as the go-to thought leaders within commercial real estate transactions. Reesa has recently merged with OCO who have been at the cutting edge of flexible serviced space provision for the last 4 years to further strengthen our offering to the occupier.

We have worked with some of the largest multi national corporations and small local businesses alike.

Our Services

Through experience, we understand the issues facing commercial property occupiers and how much time and money is at stake. Seeing ourselves as an extension to your team we've developed a depth of services that respond to moments of growth/change as well as during occupation.

Piers Barttelot Mrics


Piers has been in the property industry for over 20 years. For the first 10 years he acted for blue chip occupiers and developer landlords in one of the biggest real estate practices globally, learning his trade. Read more.

Piers wanted to further progress his career and moved with the firm to the Middle East to set up leasing operations in Abu Dhabi.

After 2 and half years Piers was approached to head-up commercial leasing and asset management for one of the world’s largest Sovereign wealth funds where he was responsible for leasing 1.9 million sq ft of office space. It was here that Piers saw the disparity of advice provided to landlords and tenants, realising that tenants on the whole receive sub standard advice compared to landlords.

Piers wanted to practice what he preached and set up Keystone CRE, a tenant only consultancy in London, which later merged with other like-minded professionals to form Reesa.
