We make building projects decision-ready.
Alpha Quadrat is a German planning and project management company. We deliver building design, project management, expert reports and construction supervision to German standards, for public and private clients in Germany and, together with local partner firms, abroad.
Four fields of work, one responsible partner.
Project development
Needs analyses, feasibility studies, option comparisons and investment planning that turn an identified need into a fundable project.
Project management and owner support
Costs, schedules, quality and risks under control: coordination of designers, structured reporting and decision papers for your board.
Building design and technical assessment
Surveys, permit design, technical statements and private building damage assessments, led and personally signed by our chamber-registered architect.
Expert reports at fixed fees
More than twenty services from building damage reports to technical due diligence for investors, each with a fixed fee agreed before you commit.
We plan in Germany. You build anywhere.
We work with chamber-registered architects (Architektenkammer NRW) and engineers experienced in large-scale projects, including airport infrastructure. We deliver design, technical due diligence and construction supervision to German standards (Eurocode, DIN), as your single contract partner, responsible for the result.
Our delivery model is built for international clients: BIM-based remote planning from Germany, a licensed local architect of record in your jurisdiction, and on-site presence at key milestones. Fixed-fee packages per project phase keep budgets predictable.

Nothing gets built until everything adds up.
Needs, options, costs, approval: we bring order to your project before the first machine moves.
Five commitments you can hold us to.
Reply within one business day
Every enquiry receives a personal answer within one business day, not an automated confirmation.
Fixed fee before you commit
After a short scoping call we quote a fixed fee. You never commission work without knowing its cost.
One point of contact
From the first call to handover, the same person manages your project.
Board-ready documents
Our reports are prepared so you can take them straight into your committee, council or investor meeting.
Straight talk
We tell you what does not work, before it costs money.
