Explanatory Note.

(This note is not part of the regulations, but is intended to indicate their general purport).

These regulations amend the Building (Planning) Regulations, 1956. The only substantive amendments are to Part Ni (Heights, Võlumes, Open Spaces) and Part IV (Lighting and Ventilation).

Heights, Volumes. Open Spaces.

Regulation 6 amends the requirendeats as to beights of buildings and get backs of main walls on corner sites. Regulation 17(2) of the Principal Regulo. tions militates seriously and unfairly against the owner of a corner site which fronts on a wide street and is bounded on one side by a narrow street. This matter was brought to the altention of the Building Authority shortly after the Building (Planning) Regulations, 1956 came into operation and a letter was sent to all authorized architects advising them that a modification of this Regulation would be granted under certain conditions, and many such modifications have in fact been granted. The ameaded Regulation 17A is in general accordance with the conditions under which these modifications are now being granted,

Regulation X., Regulation 19 of the Principal Regulations provides that where a site or building ahurs on a permanent open space such site or building shall be deemed to abut on a street equal in width to the distance acrosa such open space up to a maximum of 100 ft. No provision was made for sites or buildings which frohr on an open space but which are separated from it by a street. Regulation 8 of the new Regulations provides that where a site or a building fronts or abuts on an open space the height of any building on such site shall be determined by the Building Authority.

Lighting and Pentilation.

Regulation 13 rescinda regulation 26 of the Principal Regulations and replaces it by four new regulations dealing with the lighting and ventilation of rooms used for habitation and offices, The main changes here are that:-

(a) Light and air are required to be provided within the boundary of the lot. (b) Provision has been made for the maximum distance that any part of a room may be from the window affording it the light and air required under these regulations.

(e) The requirements of Regulation 26(4) have been amended and provision has now been made for the minimum amount of light and air to be provided for domestic or office rooms ventilating into open or enclosed courtyards by laying down the maximum angle between the sill of the window and the top of the opposite wall.

Regulations 16 to 18. Regulations 29, 31 and 32 of the Principal Regulations have been rescinded and replaced by two new regulations which provide that¦-- (a) Offices which do not comply with the minimum requirements for natural lighting and ventilation may be permitted provided that they bavo adequate mechanical ventilation and artificial lighting.
