our services
FirstFourth LLP is a design consulting firm.
Although we like to call ourselves an architecture firm, we are interested in the broader implications of design within the context of the built environment. If you have something you would like designed, we're your company.
For typical architecture projects we phase our work into four sections: schematic design, design development, construction documentation, and oversight.
