Norms and regulations, structural limitation and specific functional requirements all seem to limit and influence the designer’s scope. In reality, constraints often become the means of innovation enabling the formulation of new, unprecedented answers. This is particularly true within restructuring practices. Strictness is required to provide spatial, structural, morphological and hierarchical consistency, while the incoherent elements can be exploited as opportunities to look at designing freedom and its unexpected effects.

The designs and works published in this website represent significant opportunities for research, knowledge, and dialogue. This selection is intended as a small tribute to our clients that, since 1997, have been a core part of PWSA professional life. We continue to face many challenges every day on very different themes with various scale and approaches: domestic projects, public places and buildings, retail spaces.

From each, we learn new insights and develop new ideas that we leverage in all our projects.


Geometric design of the space

Spatial composition and its elements are simplified through dialogical and balanced forms. Geometrical setting of the internal spaces helps to find either simple or very complex harmonies, giving evidence to the perspectives and leading the eyes.

Spatial connection/transition

The elements of connection and passage between the spaces are conceived not as simple functional elements but as full perceptual experiences. In particular, the staircase has a unique property, that of allowing us to see other spaces connected to it by different points and heights, in order to obtain new inner perspectives.


Paths and prespectives

Driving in space, easing an effective and natural assessment of the quality of rooms and materials, asks for a special design. The project focuses on the spatial movements starting from the beginning, playing with lights and shadows, perspectives and geometric games.

Volumetric complexity

Contemporary living conditions are increasingly demanding for a strong space connection. Open spaces, homologated altimeters, vertical barrier elimination, etc. lead to a loss of hierarchies and sometimes a banalization of spaces. Accurate design of the altimetric transitions, together with an innovative surface treatment, contrast these effects, creating characterization and volumetric wealth, particularly in the ceilings.


Regeneration: an eco-opportunity for a new life of the buildings

Structural and foremost limits in buildings to be restored are often a heavy conditioning of architectural quality. The study of prospects and the re-composition of internal volumes in a new order can instead renew / revolutionize the perceptual experience. The reuse of buildings can be an opportunity for innovation / revolution, even where it seems impossible. The tools for implementing it in the exteriors and in the prospects are the simplification of materials and shapes, and the reinterpretation and hierarchy of the facade elements.

Transition between daylight and artificial lighting

The transition between natural and artificial light is one of the themes that make spaces live worthy and full of quality. Lights catch only the necessary elements, with possibilities of combining multiple scenes, designing not only the light but mainly the shadow which enhances it.


Heritage and enhancement

The quality of urban space emerges from features of building and architectural heritage and from plant morphologies. Minute details, slight differences, field textures and property divisions turn into elements that enhance the project on small scale, starting from the bottom, forcing rigidity and artificial abstract geometries.

Project's Multiscalarity

Territory offers to the project the possibility to face problems on variable scales. At the same time, the project’s goal is to pick on meanings and geometries that intertwine going from a different scale to another.


Public space

In the modern city, swinging between opening and closing instances, emerge two relevant issues: safeguarding the historical value, architectural and industrial, and the web (digital and physical) of the public space. Knowing how to deal with these issues comes from a long tradition of public spaces preserved in historical cities (at least in Europe, and mostly in Italy) and it’s a bright and very rich abacus of volumetric plans, hierarchies and compositions, which can become, when properly reworked, a powerful instrument supporting creativity.

Urban and territorial projects

Projects, contests and achievements allow us to develop research hypothesis on the modern city as an environment of sperimentational urban planning. New costruction, transport and communication technologies update themes and matters of social inclusion, cohabitation, work and movement.


New cities in the world

In the new housing and urban structure experiences, in european contexts, and even more: african, asian and australian environments, we have followed a systemic approach. This has become an important methodological instrument to study: cities in a rapid evolution in South Korea, the industrial and portual structures in Sydney’s Bay, historical palaces belonging to the Hu Tong family in Beijing, the newly founded University Campus of Soba in Khartoum (Sudan) and the new urban projects in Angola and Cameroon. Significant collaborations with other studios (F.Mancuso, M.Fantin, B.Dolcetta and T.Scarpa) were needed during the planning phase of medium and large settlements in Italy and abroad.

Strategies, planning and complexity

To the growing demand of planning and sustainable management of the territory, we answer with precise and systemic strategies. Planning relies on generative capacity of singular urban projects. On the other hand, sustainability relies on the possibilities created by architectural and functionality of assets and contexts.

Davide Longhi

Davide LONGHI was born in Vasto, Italy in 1969.
He graduated with honors in Architecture in Venice with an urban design thesis.
Winner of Max Kelly postgraduate scholarship to study Sydney Harbour’s Metropolitan
Strategies, promoted from the Australian Government of NSW .

He obtained a PHD in International Quality of Design with a thesis on urban
development in Asian cities.
He lives and works in Padua where he founded in 1999, PWSA, PatchWork Studio
Architects, a versatile container of studies, designs and projects.

The most important of his research themes is about the origin and transformations of
public spaces and wide-area planning; he won the national prize of Gubbio for the
squares of Pastrengo-Verona.
He has been following through the years, a lot of urban projects in Veneto Region,
working since 2006 on the PTRC, the Strategic Regional Plan of Veneto.

He has also worked on many residential projects around the world.
He loves a functional and creative home, at the same time. Fresh spaces but full of
life, and where the internal-external relationship is the key to interiors paths and
He is a lover of 1950s / 1970s design, especially Italian and American, and he loves to
include vintage pieces of modern design in his projects that he looks for with care.
Often the design of the stairs inside his own homes are coming a spatial landmark
and an interesting opportunity for a change of perspective within domestic spaces.
He loves designing the scenographic transitions of environments with light, which,
especially in the evening, light up with atmospheres.

He has followed numerous projects for shops and chains, and tries to respond with
innovative and functional spaces to the different types of merchandising.
Behind choices it often hides a very complex marketing strategy and a strong focus
on cost control. Above all the shops tell the expertise and professionalism of industrial
groups or enthusiasts about watchmaking, wine, food, coffee or producers of sofas
and furniture dealers.

He was the curator of the exhibition “Twentieth Century. Architectures and cities of
Veneto”, event of the XIII Biennale of Architecture in Venice and the author of the
eponymous volume.

He has held seminars, conferences and workshops In many universities: Sydney
(Sydney University and University of Technology, Sydney), Seoul (Myongji University),
Beijing (Tsinghua University), Brussels (Institut Supérieur ’’Architecture Saint-Luc),
Nancy (Ecole de Architecture), XXV and XXVI ILAUD (International Laboratory of
Architecture and Urban Design).

He has taught at:
2014-2015, University of Ferrara;
2014-16, Future University, Sudan;
2001-2013, IUAV University of Venice Faculty of Architecture;
2012-2013, University of Padua, Faculty of Engineering and Architecture;
2011-2013, Erasmus Intensive Programme (IP)
2004-2008, IUAV University of Venice, Faculty of Spatial Planning;
2005-2006, École National Supérieure d’Architecture in Strasbourg;
2003 École d’Architecture de Nancy;
