SECTION R301.9

RESIDENTIAL BUILDING DESIGN CRITERIA(These paragraph numbers do no t correspond to IRC numbers)

Purpose. The principle purpose of the Commentary is to provide a basic volume of knowledge and facts relating toOBO residential construction. This Commentary is to be used in conjunction with theBuilding Code of the OverseasBuildings Operationsand not as a substitute for the code. The Commentary is advisory only; the code official alonepossesses the authority and responsibility for interpreting the code.

AMBASSADORS RESIDENCE (CMR)

1.0 General

1.1 Background. The Ambassador is the personal representative of the President of the United States to thehost country. He or she explains and interprets U.S. policy and promotes the U.S. position with the localgovernment. As the chief of the U.S. Mission in the country, the Ambassador coordinates the total U.S.presence there.

1. Image.

As with all official American facilities in foreign countries, the Ambassador's residence(CMR) is symbolic of the U.S. presence. The desire for American standards of high quality andcomfort should be tempered with respect for local customs and traditions, and sensitive to theimage projected to the local populace. The CMR should express its representational nature interms of quality rather than luxury, respect rather than dominance, and openness rather thanisolation.

2. Function.

The CMR serves as the private residence of the U.S. Ambassador and family as well asthe official point of reception and entertainment for local officials and dignitaries. Both functionsshould be comfortably provided for and clearly separated in the design of the facility.

1.2 Recreational Facilitiessuitable to the local climate and site shall be provided on the grounds of the CMR.Amenities such as a swimming pool and tennis court are especially desirable where opportunities forrecreation and entertainment are limited or nonexistent for Americans in the host country.

1.3 Guest Parking shall be provided on the grounds. Provide a separate parking area for employee andservice vehicles. Parking for Embassy staff using the recreational facilities may be provided in either of thetwo areas or in a separate location, at the designer's discretion. Direct access to the recreational facilitiesfrom the staff parking area is desirable.

1.4 Groundsof the residence shall be attractively landscaped utilizing indigenous and easily maintained plantsand supporting elements. Terraces and gardens may be incorporated to extend formal entertainmentfunctions outdoors where the climate permits.

2.2 Site Requirements and Amenities

2.2.1 General.

The development of the site is an important element in the design of a CMR. Siteamenities can enhance security and provide facilities for recreation, outdoor entertainment, and

on-site circulation. Where the climate permits, open terraces, a swimming pool with cabaa, atennis court and gardens shall be provided. In colder climates, a greenhouse is necessary. Allresidences require a security gatehouse. Members of the American Embassy staff and theirfamilies are frequently invited to use the recreational facilities at the residence when they are not inuse by the Ambassador. For this reason, a fenced separation is normally provided around thetennis court, pool and cabaa to provide privacy for the family. Parking for pool and tennis courtguests may be separate or included in provisions for employee, service and guest parking. Ineither case, the parking should not be visually obtrusive to the tennis and pool areas. In mostoverseas posts, a remote generator must be located on the site, convenient to the service area ofthe residence but hidden from view. Security aspects of site requirements and amenities varybetween posts, and are determined by specific situations such as whether or not the residence isto be located on the Embassy compound.

2.2.2 Security Gatehouse.

Refer to OBO-ICS IZC Chapter 5 for requirements.

2.2.3 Landscaping and Perimeter Barriers

Landscaping of the site of an Ambassador's Residence is akey element in the design. The use of trees, shrubs, flowers and lawns should be planned toenhance the structure and the site, and to contribute to their overall appearance and good taste.Care should be taken to use plants that are easily maintained and will grow in the local climate andenvironment. A key role of the landscaping is to provide "line of sight" security by preventing directviews into areas of the building and site normally occupied by the Ambassador, his family andguests. The security requirements for perimeter barriers vary in accordance with separatelyprovided project-specific requirements, and should be verified with OBO before beginning design.

2.2.4 Verandas and Outdoor Terraces.

The representational areas of an Ambassador's Residence canbe greatly enhanced and enlarged by the use of verandas and outdoor terraces. Where practical,verandas or terraces should be adjacent to the Salon and State Dining Room. Accessibility ofoutdoor representational areas to the physically handicapped shall be provided in accordance withChapter 11 of the OBO-ICS IBC. Careful attention should be given to "line of sight" security. Thesize of these outdoor spaces will depend in part on climatic conditions. In moderate climates, thefollowing minimum sizes are recommended:

1. Category I - 70 SM

2. Category II - 56 SM

3. Category III - 46 SM

2.2.5 Swimming Pool.

Where climatic conditions permit swimming during three or more months of theyear, a swimming pool should be provided. See Section OBO-ICS IBC Chapter 31.

2.2.6 Cabaa. At residences with swimming pools, provide a cabaa to serve both the swimming pooland the tennis court. At Category I posts, include a small "wet" bar. The cabaa should beaccessible to the family entrance of the residence and to the appropriate guest parking area. Thecabaa shall be sized at 65 NSM for Category I Posts and 46 NSM for Category II and III Posts.
