Development strategies and masterplans
We determine what makes sense to develop on a site and how it should be organised. We define the programme, spatial structure, density, phasing and character of the place.

GUSt / Alexander Gast’s architectural practice
We develop site development strategies, masterplans and architectural concepts for developers, property owners, local authorities and development agencies. We help set the direction and resolve key design decisions before detailed design begins.

02 / Approach
The early stages offer the most flexibility to adjust the development programme, building size and layout. We test the main options and develop a concept that can guide detailed design.









We connect the site, programme, constraints, architecture and public space. Individual decisions have to work as one system.
We define the uses and layout of the site, building types and volumes, architectural character and public spaces. The scope is tailored to each project.
We hand the concept over to the team responsible for detailed design. Where ongoing support is agreed, we help develop the details and preserve the key design decisions.
The result is clarity on what to build, how it should work, and which decisions must not be lost at later stages.

03 / Author-led practice
I personally lead every project — from the first conversation and development of the brief through to the final concept. The team is assembled for the specific task, but the key architectural decisions remain in my hands.
04 / Contact
Send the site address, existing surveys or plans, or a short description of what you need. That is enough to start a conversation.
