Architectural Focus: modern and classical townhouses (terraced houses in UK)  completed with design descriptions, layouts, CAD resources and 3D models ready for download.

The BibLus know-how blog regarding architecture technologies and software presents the first of a series of in-depth articles. In this issue, we’ll be taking a look at this 'Townhouses' project dedicated to this particular building typology.

We’ll focus on the technical characteristics of the different building types starting from the most common;  a detailed analysis of individual projects among the best known works of various worldwide known famous architects.
Each topic will be enriched with images, renderings and technical drawings (plans, elevations, cross-sections) reproduced in .dwg CAD file formats and available for download.

In most cases, we’ll even go through a design exercise specific software solutions: for some of these projects, we’ll be providing short videos in order to the construction methods used in the BIM model.

And finally, thanks to virtual reality, users can even navigate within the project, using the shared viewing possibilities offered by this technology.

The various insights are structured as follows:


  • Townhouses: definition and characteristics
  • Townhouses of famous architects
  • Famous projects of townhouses:
    • Lafayette Park by Mies van der Rohe
    • Malagueira district of Alvaro Siza
  • Types of townhouses
  • Modern townhouses:
    • in Amsterdam: on equal plots, different and non-repetitive design solutions
    • Water Villa's: built on several levels, placed side by side and realized through translation and rotation of the single units
  • Townhouses with patios and gardens
  • BIM example projects of townhouses
  • Examples of townhouses with patios and gardens



So let's start from this widely used construction typology, what elements are used to characterize them and what elements are used to evaluate the design process.
This then leads us on to focusing on the details of some examples of famous classic and modern townhouses re-proposing technical solutions and renderings.

Townhouses (or Terraced houses): definition

Townhouses (terraced houses in UK) are a type of building configuration mainly intended for residential uses and consisting of a plurality of housing or single-family cells (at least 3) each placed side by side:

  • each housing unit is normally separated by means of common border wall arranged on the plot boundary;
  • generally characterized with a narrow front to gradually grow in depth and height following the floor levels and a small garden.


Scheme of terraced house with subdivision of spaces

The standard unit (which is the intermediate unit and not the head unit) is placed next to 2 other cells arranged along the sides.

As a building typology, townhouses are suitable for an extensive use of the territory, ie areas with a low building ratio index.

Historically, terraced houses have been the building element that has most characterized the expanding of medieval cities: their development is due to the formation of classes of craftsmen who built their homes along access roads forming villages, linear settlements adhering to the route. .They are therefore created in response to the constructive and functional needs of those sections of the population: needs that can be summarized in the need to adopt a simple, economic and tested (therefore reliable) construction practice and to have space for productive and commercial activities, as well as a modest amount of land for the production of livelihood goods (the forms of self-production and self-consumption characterize the high-medieval period).

Today they have been revisited to meet the needs of a detached house but with lower costs compared to the single house, both in production and maintenance.

Townhouse projects

The main characteristics for these housing types are:

  • the development on a long and rectangular footprint with a width of 5-6 meters;
  • the presence of an access road on one side;
  • two walls in common with the units side by side;
  • a vertical development from ground to sky;
  • independent entrances;
  • private spaces of outdoor relevance;
  • aggregation by partial or total lateral approach in a transverse direction;
  • only two fronts, the front and the rear, in contact with the outside.

The typical form of terraced houses is rectangular in shape, similar to a parallelepiped. Generally, it has one side twice as long as the other.

The housing units are flanked by the long side ( 10-12 m ) and the short side ( 5-6 m ) for lighting.

The trend can be linear or even curvilinear.

The construction of terraced houses in a straight line, however, can present the problem of lighting, with the exception of residential units at the ends that, precisely because exposed on the outside for three sides, could have more light than the others.

For this reason, positioned side - by- side on split level methods are also used: the diagonal positioning of the modules, in fact, allow to solve the problem of the light of all the terraced house.

The single townhouses consist of single-family units articulated on 1 or 2 levels (duplex), more rarely on 3 levels; the aggregation between the individual housing units can be by combination or overturning. The two solutions give rise, among other things, to different compositional arrangements for the elevation views.
The aggregation by tipping allows to unify the vertical of the floor plans.

In the case of duplex housing units (ie on two levels) the placement of the staircase is decisive for the distributive articulation: in this case it is more useful and convenient that the upper floor is baricentric compared to the depth of the housing to reduce the connective area.
Townhouses are part of the garages, even if these are listed separately for land registry purposes.

Townhouse settlements

The planning process of these settlements of terraced houses can be divided into three levels:

  1. morphology of the building
  2. housing characteristics
  3. internal organization criteria

Building Morphology

Compared to the morphology of the building, the classification criteria of the terraced houses are defined according to the ratio between housing and the traffic network (pedestrian streets, roads and car parks).

11 types of aggregations of terraced houses can be distinguished:

1 - Simple array, with a mixed path, for vehicles and pedestrians, each set of lodgings

2 - Double-deck, with a mixed path, for vehicles and pedestrians, distributed for every two series of lodgings

3 - Triple set-up, with a mixed path, for vehicles and pedestrians, for every three series of lodgings

4 - Quadruple housing, with a mixed path, for vehicles and pedestrians, for every four series of lodgings

5 - «Cul-de-sac», with a mixed path, mainly vehicular, with a dead-end

6 - Parking semicorte, with a mainly vehicular ring route

7 - Pedestrian halfway, with a tangent mixed path to the open side of a courtyard

8 - Isolated closed, with a mixed path along the external sides of the courtyard

9 - Isolated open, with a mixed path along the internal and external sides of the courtyard

10 - Pedestrian crossing, with a pedestrian path connecting two tangent parking areas to a mixed path

11 - Pedestrian block, with a network of pedestrian paths connected to one or more parking lots

Accommodation features

Once the building’s structure and main features defined,
an overall hypotheses in terms of housing unit organization can be taken into account including its position that can be processed and compared together with the sizing of the various activities, varying the ratio between the front and the depth of the dwelling, the number of views and the number of floors.

Criteria for the internal organization of the housing unit

Let’s now move on to the internal organization of the housing unit.

Normally there is the traditional subdivision between the living area (consisting of kitchen, living, dining and service rooms) on the ground floor and sleeping area (bedrooms and other services) on the upper floor(s).
In the case of a third floor level, it can be used for additional bedrooms or for other specific rooms (study, library, hobby rooms).
Particular problems may arise when addressing the position and the shape of the internal staircase for both distributive and constructive reasons. Usually the transverse partitions separating one housing and the other are used as load bearers, if the spacing between them is reasonable for the direct floor inter-connection purposes (between 3 and 6m).
In this hypothesis, it would be appropriate to adopt a very compact solution for the staircase, or a straight ramp arranged in the direction of the floor or, for shorter beam spans, so as to simplify the realization of horizontal partitions internal (floors) in order to optimize the various openings.

Another important variable for the definition of the floor plans is given by the garage. It can be external or internal to the main body. In the case of it being external, it can be detached or adjacent and connected. If it is internal, it can be placed in the basement, thus creating the problem of the access ramp, or more commonly at ground level, decreasing the habitable surface of the housing unit.
