our process

Hiberna provides a full service, from concept and planning, through design and analysis, to building and finishing. If you have a question about natural building or energy, we would love to help.


Together we will formulate a brief for the project, communicating with you regularly throughout the design process via our project management app Trello. During this stage, we synthesise all aspects of the brief,consider any planning constraints, and consult with specialists and local authorities if needed.

Energy modelling

During this stage we work with the ideas that fulfil the brief to the greatest extent,communicating with you via sketches and 3D models, getting your input along the way and evaluating against any constraints such budget or site.


At this stage we take the preferred concept to the next level of detail, engaging other consultants, such as engineers, as necessary. During this stage we will always model your design in PHPP energy modelling software and if necessary,will use hygrothermal modelling to test construction methods. This is a key part of the process where we can optimise the design for its energy efficiency and comfort.

We love working with clients who are as passionate as we are about the environment, quality and durability, and health and comfort. We keep our designs simple to let the natural beauty of the materials shine through.

Energy modelling is a service that we offer to anyone, whether or not they are working with our design or construction teams. Energy modelling gives designers the ability to optimise their buildings, ensuring the best possible performance in the most cost effective way.
