Our Fees
At One Four Architecture Ltd., we understand that every project is unique.
That's why our fees are customised to reflect the size and scale, type of building, complexity of the task, and the need for bespoke design work.
Additionally, how deeply our team is involved in the phases of your construction process also plays a part.
