Who We Are

Mancini Design + Development is  Design and Development firm.

We focus on sustainable design and development. We are highly specialized in renovating and developing deteriorated properties for the purpose of placing them back onto the market. Our design-build company offers design-build service, creating affordable green spaces for living, work, and play.

Mancini Design has a Philosophy of design architecture that promotes harmony between human habitation and the natural world. This is achieved through design approaches that aim to be sympathetic and well-integrated with a site; so buildings, furnishings, and surroundings become part of a unified, interrelated composition

We design spaces that are, organic, and sustainable, with spaces that can merge seamlessly through various circulation paths that include stairs, elevators, hallways, atriums, and entrance halls. These spaces can be visually interconnected with a sense of openness, motion, and with abundant natural light. Purposeful rooms that seem to merge into a single continuous space. harmony

Mancini Design + Development Who We Are

Mancini Design + Development is a full-service design firm whose goal is to create interior and exterior environments that are modern and affordable, while considering the needs of the larger community and environment. Our new residential homes will be homes that are sustainable from foundation to roof. Homes that are modern and affordable for first time home buyers who want to minimize their carbon footprint. 

We understand that building a new home is a journey. Throughout our process, we consult thoroughly with you, to understand your needs, budget, current aspirations, and future plans. This way, we can work up and offer the very best solutions for a home design that suits your lifestyle both now and in the future.  We love what we do and stay up to date with modern trends and developments. This keeps our designs fresh, ensuring that you always get the very best in contemporary modern design. We’re intent on achieving designs that deliver you long-term benefits and timeless value. 

Providing Solutions

The McMansions: inefficient old homes; and yes, some standard new home construction, represent the old way mentality. The new goal is to build efficient homes that are inexpensive to operate and will be low maintenance.

Our challenge, through a rigorous research based approach, is to find the building components that will support this goal. The homes will offer a flexible floor plan and support a live/work/play lifestyle. Bridging the gap between formal and informal.

Our Philosophy

To implement design and construction methods in harmony with the natural environment and community. Implementing LEED and Energy Star methods we design, renovate, and build healthy places to live, work, and play.
We want to create personal environments that enrich both our clients’ quality of life and the fabric of the immediate surrounding environments.

What We Do

“To many people, the impact of a changing environment seems distant and completely separate from our existence until we are directly confronted with the negative results. “Poorly conceived design divides us in urban areas from our wilds and has contributed to seeing nature as something isolated from us. Yet reinvigorating our bond with nature is a challenge design professionals are well placed to address. Architects and designers have control over our built environment; by changing the way we design cities and buildings to connect to rather than disconnect from nature, we can change our proximity to nature and shift our physical relationship to the environment.” (Smart cities)



We purchase property that typically requires substantial renovation.
We prefer buildings that are in shell or outdated mechanical, plumbing, or electrical condition but are structurally sound, primarily at the foundation.

This strategy ensures that all new mechanical, electrical, and plumbing systems will be installed into the project.
Any structural issues can be addressed without concern of damaging existing walls or fixtures since many of these items will be stripped from the property.


Assessment is made of the condition. Pictures are taken for documentation. An initial cleanout is done if needed. A plan of attack is then established beginning with structural repairs. This consists of top to bottom examination of exterior brick and wood substrates, interior foundation, joist, and roof. Rotted wood structure is removed and replaced. Foundation walls in the basement and exterior brick joint lines are cleaned and pointed. New electrical service is installed along with new wiring,  outlets, and switches. New plumbing system is installed along with a high efficiency hot water heater. A high efficiency HVAC system is sized and installed and radiant floor heat is considered. To minimize energy waste and maximize energy cost savings insulation quantity is factored for the project based on the project's location. Critical research is done to establish r insulation values for foundation, under slab, walls, and roof.   Energy efficiency appliances and fixtures are implemented throughout all phases of renovation.Window and door R values are analyzed to determine if double pane or triple pane windows and doors are required.

Modular Architecture

As every professional in the building industry knows, construction can be a costly and endlessly time-consuming endeavor. Delays are almost more frequent than on-time construction, and can be induced by extensive bureaucratic requirements, weather and other unexpected circumstances, inadequate planning, too few personnel, or a whole host of other causes.

Per the Modular Building Institute, the industry’s largest trade association and foremost resource, “modular construction is a process in which a building is constructed off-site, under controlled plant conditions, using the same materials and designing to the same codes and standards as conventionally built facilities – but in about half the time." Modular construction is also a bit of an umbrella term that includes a couple of different types of construction:

  • Volumetric modular construction is a process in which entire rooms or sections of rooms—complete with walls, floors, and ceilings—are built in a factory setting and then transported to a final site for assembly. This type of construction is used for both permanent and relocatable modular projects (buildings that aren’t designed to be moved versus those that are; think a hotel versus a temporary classroom).

* Panelized construction is a process in which interior and/or exterior wall panels are built in a factory setting and then transported to and arranged on the building site. The rest of the building is constructed on-site.

The benefits of modular construction compared to traditional construction methods and it’s cost-saving. Modular construction certainly can save costs, but that isn’t its primary benefit. The primary benefit of modular construction is time saving and faster return on investment. Since modular construction allows for industrialized assembly in a climate controlled factory that happens concurrently with site preparation, the total time it takes to build a structure can be dramatically reduced. Often by the time the site is ready (foundation levelled, plumbing in place, concrete poured, etc.) the factory-built modules are ready to be placed. A modularly-built hotel, for example, can open its doors and start generating revenue 30%-50% sooner than a traditionally-built hotel.

Modular construction is sustainable.

Modular construction is considered a more sustainable option than traditional construction methods for a few reasons:

Less material waste. When building in a factory, waste is eliminated by recycling materials, controlling inventory, and protecting building materials.

* Improved air quality. Because the modular structure is substantially completed in a factory-controlled setting using dry materials, the potential for high levels of moisture being trapped in the new construction is eliminated.

Modular building types.

Any type of building can be built modularly. But to do so, the building has to be conceived of and designed as such. Modular construction is often chosen when time is of the essence or space is at a premium. For example urban lots are very often constrained by roads and other buildings, so building traditionally (bringing materials and workers onsite for an extended period of time) can be prohibitive. With modular construction, you need far less personnel to erect the building in less time. And, in tight urban locations, the reduction of noise pollution is an added benefit.

Technical requirements.

Whereas traditional construction can be a more fluid process wherein design changes are introduced even after construction has begun (often causing delays), modular construction requires design professionals to collaborate and complete their work upfront. It’s during this process that modular construction—permanent modular construction, most notably—usually relies on advanced BIM to assess energy performance and identify the most cost-effective efficiency measures. The designs are then turned over to the manufacturer for industrialized prefabrication and construction.
As far as design constraints, modular buildings are built to the same building codes and specifications as traditional buildings and are virtually indistinguishable from their “stick-built” counterparts. From single-family homes to multi-story office buildings, modular construction can be used anywhere.

Measured Drawings and Construction Documents

The designer as developer’ engages in the acquisition and development of land: Land-to-Architecture, for the betterment of the environment through harmonious project design.

By developing, constructing, and designing its own work the firm is the designer and becomes the owner, therefore eliminating the client and the general contractor from the design and building process. The firm is then in full control to create better city environments for the community as well as achieve financial satisfaction

Modern Row Home Design

Philadelphia is largely a row home city. Philadelphia row homes evolved early in the city's history, and were designed by anonymous Colonial craftsmen and the city’s most distinguished architects.

Rowhouses have a special presence. Their relationship to the street, private gardens, their intimate scale and expressive details, have helped drive a renaissance in rowhouse living.

As the kind of residential architects Philadelphia appreciates, we specialize in Philadelphia row home renovation with the goal to innovate and creatively transform older rowhomes into modern, cleverly designed living spaces, using low-environmental impact materials, energy and design.


Whether it’s the view from a second-floor window, or the sanctuary of a private garden, it’s always possible to create moments away from the bustle of the city.


Within the bricks and beams are the layered stories each rowhouse tells. Every time we refurbish a banister, replace a cornice or straighten a tilting iron railing, we bring these artful details back to life.


high ceilings and peaceful outdoor spaces, Light-filled space, front and back; green roofs and passive house approaches; – we design and celebrate these nourishing rowhouse qualities.
