Cubic Building Surveying

Two Decades of Shaping London and the Home Counties

We believe that property projects shouldn't be a source of stress. For over 20 years, we have operated as a dedicated 'one-stop' consultancy, guiding homeowners and investors through the complexities of the UK property market. Whether you are planning a sophisticated loft conversion, a large-scale refurbishment, or a bespoke new build, we provide a seamless transition from initial concept to final completion.

Our approach is defined by a hands-on philosophy. We don't just sit behind desks; we immerse ourselves in the technical details of every site. By combining our deep knowledge of architectural detailing with a pragmatic professional approach, we ensure your project is both ambitious in design and economically feasible.

A Multi-Disciplinary Team at Your Side

When you hire us, you gain access to a diverse pool of expertise. Our team is led by Simon Coles, our founder and Director, who brings over 20 years of building surveying consultancy experience. Simon’s technical skills on-site and his membership in the Faculty of Party Wall Surveyors ensure that even the most complex boundary disputes or structural challenges are handled with precision.

Our design vision is driven by Alex Jarzcok, our Senior Architectural Designer. With a particular flair for re-modelling and re-configuring existing spaces, Alex transforms how people live in their homes. Supporting our technical delivery is Glyn Beynon, who brings vital Health & Safety expertise (SMSTS qualified) and project management rigour to every site.

For larger commercial and residential ventures, James Hicks—a Chartered Building Surveyor with two decades of experience—provides high-level project management, insurance reinstatement assessments, and cost consultancy.
