Design Development & Planning

Once the concept and overall vision is created, we apply this to carefully thought-out space planning during RIBA stage 2 to ensure that the design meets the client’s needs and requirements. 

After a measured survey is undertaken, we continue to develop the design through RIBA stage 3 so that additional detail is included upon the drawings with the production of accompanying design documents to form a comprehensive planning or listed building submission.

 We work with many councils and usually open a dialogue with the local authority before an application is submitted, so that the proposed scheme stands the best chance of success.

Concept & Brief

We start by establishing the brief at RIBA stage 0 & 1; testing several initial conceptual ideas to shape a space or architectural form through artistic imagery and visualisation.

We continue moulding the aesthetic with the introduction of material palettes, whilst ensuring that the project is to be functional and considered in line with budget constraints.

Detailed Design

Following the planning stages, the journey progresses into the technical design stages of RIBA stage 4, where we collaborate with the other necessary design team members and external suppliers. 

We work closely with our trusted structural and services consultants to ensure the design is fully coordinated, producing a robust set of technical drawings, details, and specifications. 

This allows us to receive accurately priced tender returns from prospective builders and subsequently progress the technical design information into a final RIBA stage 5 construction package. 


Quality control is paramount to a successful delivery of the proposed scheme.

Thomas Alexander has strong relations with several trustworthy and reliable contractors that enables efficient solutions and smooth running of our projects on site.  

Project Completion

We support our clients through the hand over and project completion, ensuring that the final finish is exceptional, and ready to be used as a home.
