Services
Full Design + Planning
We provide comprehensive architectural services from initial concept development through to planning approval. Our process includes detailed design iterations, regulatory compliance checks, and technical documentation required for construction. Clients benefit from our expertise in navigating complex planning systems while maintaining design integrity throughout the project lifecycle.
Architect Consultation
Our consultation service helps clients explore design possibilities and feasibility studies. We assess site potential, budget constraints, and planning considerations to develop practical solutions. This service provides clear direction for projects at any stage, ensuring informed decision-making before committing to full architectural services.
Preliminary Sketch
We create initial design proposals to visualise project potential before formal planning. These sketches establish spatial relationships, material choices, and overall aesthetic direction. This service allows clients to explore multiple design options while maintaining flexibility before detailed planning documentation begins.

We specialise in low-energy building techniques demonstrated by our Passivhaus-certified projects. This service ensures buildings meet rigorous environmental standards while maintaining contemporary aesthetics and functionality.

This service guarantees ultra-low energy consumption while maintaining superior indoor comfort levels through precise architectural detailing.
