Things I have learnt during the week with Sharon’s team


Day 1: Revision on Consultant’s descriptions Day 2: Update of new planning applicationsDay 3: Meeting for discussion of XRL MLP

Things I have learn on job done


Day 1: Revision on Consultant’s descriptions

• Rectify their minor mistakesConsultants are prone to make presentation mistakes which should be corrected once discovered

• Include necessary contents All information found in the amendment report useful for the application should be put into the descriptions

• Familiarize with the stuffs on hand To make sure the above points to be achieved, all the stuffs available on hand should be read through


Day 2: Update of new planning applications

• New applications or further commentsInformation on applications are published in every Tuesdays / Fridays in the webpage of Town Planning Board.

• Newspaper Notice of Development ProposalNewspaper Notice will be published for new applications, and there will be 3 weeks time for public comment

• Gist of Development ProposalThis includes the application and site details such as address, applied uses, PR, SC etc, and also a layout plan


Day 3: Meeting for discussion of XRL MLP

• CDA requires a set of MLP

• Sites with strong urban design needs more specific building details

• Circulation of plans to different departments for approval

• Focus of the Planning department

• Constraints in design in order to meet building/planning requirements


Concept Plan for applicationFor general applications• Site boundary• Blocks layout• Land uses• Zoning in each floor• Heights & # of stories• Vehicular assess• Carpark, L/UL• Non-building areas• Section, elevation

For sites including consideration of landscape, environment, infrastructure and GIC

• EVA• Landscaping• Environmental• GIC• Building services• Open spaces• Pedestrian paths


Extra details in KCRC’s MLP for Tai Wai

• Purpose, Background information, previous documents

• The subject site (development parameters, parking provisions) and surrounding land uses

• Planning vision, provision of education institution

• MLP: building design, voids, LMP, maximum height, vehicular and pedestrian circulation diagram, GFA calculation

• Traffic assessment report and study


Extra details in MTR’s MLP for Tai Wai• Purpose, Background information, Planning history

• Changes in planning with reasons, design merits, previous documents

• The subject site (development parameters, parking provisions) and surrounding land uses

• MLP: building design, voids, LMP, maximum height, vehicular and pedestrian circulation diagram, GFA calculation

Focus of Planning Department

• Set back

• Percentage of Greenery

• Conservation of mountain ridge line (5-10%)

• AVA

Conflicts in design

• Possible solution: self-definition, presentation methods…


What kind of sites needs AVA?• (a) Planning studies for new development areas;• (b) Comprehensive land use restructuring schemes, including schemes that involve agglomeration of sites together with closure and building over of existing streets;• (c) Area-wide plot ratio and height control reviews;• (d) Developments on sites of over 2 hectares and with an overall plot ratio of 5 or above;• (e) Development proposals with total Gross Floor Area exceeding 100,000square metres;• (f) Developments with podium coverage extending over one hectare;• (g) Developments above public transport terminus;• (h) Buildings with height exceeding 15 metres within a public open space or breezeway designated on layout plans / outline development plans / outline zoning plans or proposed by planning studies ;• (i) Developments on waterfront sites with lot frontage exceeding 100 metres in length; or• (j) Extensive elevated structures of at least 3.5 metres wide, which abut or partially cover a pedestrian corridor along the entire length of a street block that has / allows development at plot ratio 5 or above on both sides; or which covers 30% of a public open space.


Day 4: Town Planning Ordinances, Draft Planning BriefDay 5: Landscape Master Plan, Sustainability study

Things I have learn on self-study


TPO Section 12• Amendment of plans on application to the Board

• “application…be accompanied by the prescribed fee”

• “any proposal in relation to an original approved plan”

• “no proposal…shall relate to…relevant draft plan”

• “obtained the consent in writing of each person (other than himself) who is a current land owner in respect of the application”

• “shall cause a notice…to be published in 2 daily Chinese language local newspapers and 1 daily English language local newspaper once a week during the first 3 weeks…”


Section 16• Applications for permission in respect of plans


• “draft plan or approved plan, whether prepared or approved…provides for the grant of permission”




Section 16A• Amendments to permissions in respect of plans


• “be read as having effect subject to any amendments which are Class A amendments…apply to the Board for… Class B amendments”




Other sections• Section 17: Right of review

• “within 21 days of being notified of the decision of the Board, apply in writing to the secretary to the Board for a review of the Board's decision”

• Section 17B: Appeals

• “…by lodging, within 60 days after notification of the Board's decision under section 17(6), a notice of appeal”

• “Any notice or order of an Appeal Board shall be issued under the hand of the Chairman or a Deputy Chairman”


Draft Planning Brief• The Site and its Surroundings

• Planning Intention

• Development Restrictions

• Development Parameters

- Height- Non-building area- Urban and Landscape design

• Developmental comments

Form basis for the later design in Master Layout Plan


Landscape Master Plan• Submissions needed only when required in

planning permissions or leases conditions where new landscape features are required to fulfill planning conditions

• Prepared by a Registered Landscape Architect

• LMP submitted for compliance with planning conditions will be processed within 6 weeks from the date of reciept

• For building proposals involving amendments to schemes previously approved by the TPB, fresh planning applications may be required


Landscape Master Plan Proposals

• Existing trees assessment, transplanting and plantation of new trees

• Landscape design concept

• Design standards

• Soft and Hard Landscape Area Provision

• Landscape Master Plan (CAD with labelling, different viewing angles, floral design, recreational facilities, sample pictures, 3-D visualisation…)


Sustainable building design

1.High density development in HK

2.Bldg. Department Research (06)

3.11th July, comment from HKIA

4.What RLP generates?



Challenges: High density, >6000p/km2

HK has the highest transport efficiency, yet:

Urban temp escalating

Increasing # of hot nights

Less sunshine spread germs

Higher humidity

Reduced wind flow

Increase chances of sickness



Pland + CUHK: Urban Climatic Map Bldg design research

Background: 1) review existing bldg regulations

2) promote new planning concepts

InternalLocal

RegionalGlobal



4 points to tackle:

• Air ventilation• Heat Island effect• Pedestrian• Greenery

3 ways to address:

• Building separation/premeability• Site coverage of greenery• Setback for air volume


Overall framework:

• Sustainable City Programme Goals

• Building Sector Objectives

• Indicators

• Building design Guidelines

• Recommended Practices



1.Sustainable City Prog. Goalse.g. Mongkok: rely on streets as natural

ventilation

Results in poor design like Langham Place due to combination of sites by URA east-west wind flow is thus blocked

Hence:1) Street width? 2) Bldg height Bldg Permeability (P) 3) Bldg Site Coverage (SC) 4) Bldg Separation (S): 15m as a good

standard



1.Building gap: <15m = no gap for natural ventilation

2.Building site ratio <1:5


1 unitroad

< 5 unitMaximum permissible length



Other measures:

• Void deck (Singaporean term)• Sky/Podium garden• Refuge floor

Rely on Performance Based Approach

Allow more gaps in building bulk



2. Greenery Site Coverage

e.g. Tokyo: for sites > 1000m2

Green Roof >20% (by regulation)

Hong Kong: SC >30% Rationale: (Gov: 30%, Private: 30% = Total: 30%) For sites < 1000m2, SC = 20% Other elements like vertical greening and

water iiifeatures and the like are also accepted



3. Setback

Recommendations:Site with depth >17.5 SetbackMin. Sectional area of urban canyon 7.5m x 15m,So as to reduce volume of air being blocked

Tightest Freest

Recommended e.g. JPNs/PNAPs



HKIA ppt:

• Design Guidelines• GFA Concessions• Energy efficiencies

1.1 Survey conducted• Air ventilation• Pedestrian paths• Heat Island effect

>2 hectares > 60m Continuous facade



HKIA ppt:

2.1 Essential Features (e.g. ME rooms, refuge rooms…)

remain exempted from GFA Carpark is suggested to count into GFA

2.2 Green Features: remain exempted from GFA

2.3 Amenity Features: suggest to cap a maximum of GFA iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiexemption



HKIA ppt:

3.Energy efficiencies

Mandatory Building Energy Code?c.f. Mandatory Green Building Assessment

(Singapore)

4. Others Deep root problem:Redevelopment: now from PR 3-4 to PR 8-10m +

exemptionHow about just limiting the whole development

density?



HKIA ppt:

5. An ultimate goal

now HK rely on HKBEAM whereas US rely on LEED

Match HKBEAM to the standard of LEED
