  For instance, London and Athens have similar population densities; yet, the core densities in Athens are considerably higher than in London. The Athens suburbs, however, are among the least dense in Europe. Similarly, the Essen-Düsseldorf and Milan urban areas have almost identical densities, yet core densities are considerably higher in Milan (Demographia, 2015). Urban designers may encourage a variety of density and housing types in different locations to ensure distinctively different neighbourhoods and a variety of urban characters. Mixed-use describes developments and precincts that combine diverse uses, such as residential, retail, commercial and office uses, clustered together in one project. The different uses can be either layered vertically in a single building, or in a horizontal arrangement in adjacent buildings. Infill is the act of building on a vacant lot (often an underutilized site) within an otherwise developed neighbourhood. Urban Infill development occurs in the established areas of a city and can be a valid densification strategy for unoccupied gaps in already built-up areas. Urban Infill can be a medium-density growth management strategy that uses what is already there to its advantage; Infill has frequently led to thoughtful, innovative housing solutions in urban settings. Urban Infill may use modular prefabrication that allows building components to be manufactured off-site and transported to the site for assembly. Modular construction technologies could allow for entire apartments built in a factory off-site, then trucked to the inner-city site and assembled, including over multiple storeys

  9 Infill Housing Infill housing is built on vacant lots within an already-developed area that was previously occupied or never used. These sites are now taking on additional significance due to the need to limit urban sprawl. Since Infill sites are commonly located in urban areas, townhouses are suitable housing types for such projects. This chapter discusses issues related to the use of townhouses in Infill projects and examines strategies for their integration. Opportunities Infill townhouse projects have environmental, economic and urban benefits. With their high density they can house a large number of people in a relatively small area without introducing tall apartment buildings. By offering an affordable alternative to living in a detached house, these homes may appeal to singles, young couples and empty nesters inclined to buy smaller dwellings (Kinnis 1997; Moyes 1997). A desire to reduce commuting time is causing people to live closer to the city center, making Infill townhouses suitable for those who cannot afford or do not wish to own cars. Homeowners will also benefit from lowered infrastructure costs since these sites are already serviced with roads, utilities, public transportation and commercial amenities. Infill housing can also improve the urban fabric at the building, the block and the neighborhood level (Gutman 1988). They can increase density in a dispersed manner without changing the place’s overall appearance. Another advantage is revitalization. High-density Infill housing allows communities to participate in their own rehabilitation, as was the case in the Benny Farm project in Montréal, Quebec, Canada (Figure 9.1) (Hermanuz et al. 1988). Filling up vacant lots or replacing dilapidated buildings removes community eyesores and increase the property value of adjacent lots

  Santana Row is a $450 million, 1.5 million-square-foot mixed use “village within a city” in San Jose, California. The project replaced a 43-acre strip shopping center with a new landscaped urban “main street” center. Opening in 2002 just 80 days after a major fire that caused $130 million in damage, the center has proven to be enormously successful. As of 2012, its pedestrian-friendly sidewalks drew some 30,000 visitors a day for shopping and dining in its 70 shops and 20 restaurants. The four blocks of the 1,500-foot-long main street, lined with arcaded shops and three-to five-story buildings, create a lively, popular “outoor room.” Its mix of uses includes 834 residential units, office space for 350 employees, a movie theater, two parks, and a five-star hotel. Its 2008 LEED Gold six-story office tower, 300 Santana Row, includes 65,000 square feet of Class A space over a two-story retail base, as well as a stand-alone parking structure. Santana Row was named 2010 Project of the Decade by the Silicon Valley Business Journal for its transformational and economic impact on the Silicon Valley area.

  Infill development and redevelopment are critical components of urban growth. As cities build out their cores and urban growth expands beyond the inner ring suburbs, opportunities arise to intensify development in their centers. More intense central city land use contributes to reduced future sprawl, makes more efficient use of existing infrastructure, and improves overall accessibility. Usually such Infill development or redevelopment replaces existing lower-density or obsolete structures with higher-density, mixed use projects (Dunham-Jones and Williamson 2011).

  Mixed use Infill development projects are more complex and challenging than single-use and greenfield projects. The design challenge is to create a workable combination of uses that achieves coherence and synergies within the project and is compatible with and connected to the existing context of surrounding neighborhoods and land uses. The development challenge is to create a feasible financial calculus that accounts for investment capital, project costs, and multiple income streams over the life of the project. The planning challenge is to envision, plan, and operate a regulatory process that guides development toward sustainable outcomes. This involves responding to market forces for core-area redevelopment, concerns about neighborhood compatibility and development impacts, and the need for consistency with plans at the small-area, city, and regional scales.

  This chapter describes and analyzes a case of mixed use Infill redevelopment to show how dynamic financial analysis, presented in chapter 6

  Infill companies prepare well-organized ‘packages’ or ‘kits’ of parts off-site. The parts and small assemblies are delivered in the correct number, sequence and dimension, using the latest in laser tools for accurate site measurements. These packages, along with the coordinated delivery of other parts straight from manufacturers or suppliers, are bar-coded and delivered to the site and brought into the empty space through a balcony window by a boom truck or, on tall buildings, using a boom lift (also used for window washing) or via the service elevator and through the unit’s front door. Once inside, they are installed by a multiskilled team of workers who stay with the job until it is finished. Only minimal cutting of parts is required, thus producing very little on-site waste, debris and noise. Such companies will compete on their ability to use the latest enterprise management software and the latest consumer-oriented products from the market and their ability to deliver on-time and on-budget. They deliver at various price points and hand over a user’s manual and multiyear maintenance agreement.

  Working this way means an end to choreographing separate subcontractors, with all the familiar scheduling, blame-shifting and quality-control problems. This new mode of operation means implementing true teamwork into residential construction. Infill company product/service solutions are truly systematic, which does not mean uniform solutions but quite the opposite, because good systems enable rather than block variety.

  A complete Infill package will include everything making that space habitable – the thousands of discrete parts including parts for making walls, doors, door frames and hardware, all wiring, piping and plumbing fixtures, lighting, cabinets, appropriate heating, air conditioning, ventilation equipment and so on. The space may be rented and the Infill purchased. The Infill may even include the front door as well as part of the building’s façade directly related to each independent dwellings’ floor plan. (see NEXT21 at the beginning of the book)

  As already noted, social structure and conventions and the local market will dictate which parts of a multifamily residential building will be ‘fixed’ or common and which will be ‘movable’ or decided per dwelling unit.

  It’s quite reasonable to question how such businesses can operate when a building stock is highly varied. In many countries and regions, building technology (wood-frame vs. concrete vs. heavy timber vs. steel structure, etc.) varies considerably, as do access types and dimensions (e.g., floor-to-floor; column spacing; façade-to-elevator core, etc.). Given these variables, Infill companies will have developed systemic solutions, with variations. Experience world-wide shows that the routing of piping (drainage and domestic water supply), cabling and ventilation ducts within demised spaces requires special attention and offers the best opportunity for systemic product solutions.

  According to the literature, a densification of existing settlement structures is typically followed by the decreasing potential of urban ecosystem services and negative impacts on resident’s quality of life (Schetke 2010, Douglas 1983 in Priego, Breuste, Rojas 2008, de Ridder, Adamec, Banuelos. 2004, Tyrvainen, Mäkinen, Schipperijn 2007). According to Schetke 2010: 9 ‘the acceptance of Infill development is critically discussed among planners and scientists, as in most cases, local residents strongly disapprove of […] higher densities. This highlights the gap in values between local residents´ preferences and urban policies’.

  Following studies on the social and environmental effects of demolition in housing estates we know that a simple quantitative omission of built-up space does not necessarily lead to improved ecological functions and an enhanced provision of a suitable quality of life (Schetke, Haase 2008). Again, Schetke states:

  ‘We have to carefully focus on prerequisites, preconditions and socio-environmental circumstances accompanying each change – both reduction and expansion – of the urban fabric’ (Schetke 2010: 11).

  In doing so, this study introduces a quantitative approach to the impact assessment of different forms of settlement growth which integrates both the concepts of quality of life and urban ecosystem services. In the following, we address three major questions:
