Build, Design & Construct

When dealing with design and construction projects, C161 has an efficient and proven method in place to ensure that all projects completed meet the expectations of our clients.

We have forged strong connections with multiple consultants in all disciplines.  These relationships combined with C161's extensive range of experience enables us to produce quality work in all aspects of the building process.

We work closely with our clients to solve spatial challenges, accessibility issues, acoustic amenity and fire compliance whilst ensuring that the budgets set by our clients are met.  Ultimately, we aim to provide our clients with a first-class project on an agreeable budget.



C161 was founded by a group of like-minded professionals, who utilised their abilities to provide constructive solutions and to create first-class developments within the sector.  C161 brings over 30 years industry experience and is committed to providing each client with a first-class project.

Why 161?

We are often asked this question.  161, more commonly known as Phi, Fibonacci, or the golden ratio (1.618).  The ancient Greeks wrote about this ratio and even dates back as far as 300BC.  It is a ratio that appears in nature, design and everyday life everywhere you look, it is quite often referred to as a symbol of symmetry and perfection, and perfection is something that our team aspire to be able to provide to our clients on a daily basis.


Quality, Safety and Environmental:

C161 is committed to providing a safe working environment for all employees, contractors and customers.  We achieve this by ensuring that all client expectations are met and by implementing sustainable practices in the workplace.  We have an integrated Quality, Safety and Environmental system which provides our company with systematic and comprehensive processes that are required for the effective management of these activities.
