Acheiving Great Federal Public SpacesAchieving Great Federal Public Spaces builds the case for great public spaces in federal projects realizing that many of the existing spaces are not exceptional.  It is an invaluable book for property managers, developers, and anyone else who wants to evaluate and improve their plazas, courtyards, and other public spaces.

The book is both a hands-on resource with on-site exercises and a handy reference tool full of ideas and inspiration and properly suggests the points in the process to consult an architect and landscape architect professionals.

The Project for Public Spaces (PPS) has written and designed Achieving great federal public spaces: a property manager’s guide. PPS in conjunction with the US General Services Administration Good Neighbor program, has created four major sections:


1. Why great places matter and what makes a good public space
2. How to evaluate a building’s public spaces
3. What improvements work in the short-, medium-, and long-term
4. How to successfully implement solutions

The centerpiece of the book is the “Place Audit,” a detailed on-site evaluation exercise that property managers can complete on their own or with a group of stakeholders. The Audit reveals the strengths and weaknesses of a property’s public spaces. Equipped with this knowledge, property managers can proceed with confidence to implement the book’s recommendations for improvement.

Since its publication, Achieving Great Federal Public Spaces has been distributed to 1600 managers of federal properties across the United States. The Place Audit is being incorporated into GSA’s annual evaluations, and it will serve as the basis for training federal property managers in Placemaking.

Porphyry’s composition determines its high compression strength, resistance to stains, slip resistance, and high freeze/thaw ratings.  The stone is the most popular paver in Europe, and is favored for its flexibility in design, beauty, durability and low maintenance requirements. ADA Compliant Porphyry pavers are also adaptable to a permeable paving set. The stone is by far one of the most durable pavers in the world.  These materials are available from Milestone Imports.   –
