Revision
Draft 1 — Builder Brief
Project Intent
To develop a gated residential community compound organized around a central public plaza and fountain, with a cafe and toilet block near the center, detached houses arranged around the public core, one larger manor house, two car parks at the site edges, and a secure boundary wall with controlled gate access.
1. Project Overview
The compound is to be designed and built as a radial site layout. The planning intent is that the community center is the heart of the scheme, and that all main movement and visual orientation lead back to that center.
The site must be divided into five main functional parts:
- Central plaza and fountain
- Cafe and public toilets
- Residential houses
- Manor house with controlled entrance
- Outer edge car parks, wall, and security gate
The compound should feel:
- secure
- walkable
- community-centered
- easy to navigate
- suitable for phased development
2. Design Concept
The design is based on a center-outward layout.
Central idea
The fountain and OHA Plaza form the exact center of the compound.
Around the center
The cafe and toilet block sit close to the plaza and should directly support public use of the center.
Beyond that
The detached houses are arranged around the central area in a radial or semi-radial pattern, with access paths linking them back to the plaza.
At the perimeter
The car parks, wall, and security access remain on the outer edges to keep the central area free for people rather than vehicles.
3. Site Planning Requirements
3.1 General layout
The builder is to follow these basic spatial rules:
- The plaza and fountain must be set out at the center of the compound.
- The cafe must be positioned close to the plaza and must face the public center.
- The toilets must be located beside or just behind the cafe, with screening for privacy.
- The houses must be arranged around the center, facing inward where possible.
- The manor house must be larger and have a stronger entrance/gate condition than the other houses.
- The two car parks must be placed on opposite or balanced outer sides of the site.
- Vehicles must remain on the perimeter side of the site as much as possible.
- The compound must be enclosed by a wall/fence with at least one main gate/security point.
4. Functional Areas
4.1 Zone A — Central Fountain and OHA Plaza
This is the primary public space and identity element of the whole development.
Requirements
- Place a fountain or water feature at or near the exact center.
- Provide a plaza surface around it.
- Include adequate open standing/sitting space.
- Allow for landscaping, paving, and shade where practical.
- Ensure the space is visible from the cafe and accessible from all houses.
Builder intent
This space must read as the main heart of the site.
4.2 Zone B — Cafe and Public Toilets
The cafe is a central shared amenity.
Cafe requirements
- Locate close to the plaza.
- Face toward the plaza.
- Allow for indoor and/or covered seating.
- Provide service access without disrupting the plaza.
Toilet requirements
- Position near the cafe.
- Do not place toilet doors opening directly into the main public seating area.
- Provide screening wall or landscape buffer if possible.
- Group plumbing logically with the cafe building where practical.
Builder intent
The cafe and toilets should work as one service cluster.
4.3 Zone C — Residential Detached Houses
The standard housing component is a group of detached houses.
Requirements
- Arrange houses around the central public core.
- Orient entrances toward internal pedestrian paths where possible.
- Maintain separation between houses for privacy and access.
- Allow for unusual or angular house geometry where required by the design concept.
- Keep the housing ring connected to the plaza by short walking routes.
Builder intent
The houses should feel part of one compound, not isolated units.
4.4 Zone D — Manor House
A larger house is to be included as a special residential component.
Requirements
- Provide a larger footprint than the standard detached units.
- Give it a stronger arrival sequence.
- Include a gate, entrance court, or controlled threshold condition.
- Position it so it remains part of the compound but retains distinction.
Builder intent
This building should read as a principal or feature residence within the site.
4.5 Zone E — Car Parks
Two car parks are required.
Requirements
- Provide Car Park A on one outer side of the compound.
- Provide Car Park B on another outer side of the compound.
- Keep parking toward the perimeter.
- Avoid routing cars through the central plaza zone.
- Size car parks according to final occupancy and expected visitor demand.
Builder intent
The compound center must remain pedestrian-oriented.
4.6 Zone F — Boundary Wall and Security Gate
A perimeter enclosure is required.
Requirements
- Provide a full or controlled perimeter wall/fence.
- Provide a main gate and security/entry point.
- Ensure visibility and controlled entry.
- Integrate the gate into the overall arrival sequence.
Builder intent
The enclosure should provide safety, identity, and order.
5. Access and Circulation
5.1 Pedestrian movement
Pedestrian routes must be prioritized inside the compound.
Requirements
- Main walking route from gate toward plaza
- Walking connections from all houses to the plaza
- Direct access from houses to cafe
- Safe path to toilets
- Safe circulation around fountain/plaza
5.2 Vehicle movement
Vehicle movement must be limited to the outer site zones.
Requirements
- Vehicles enter through gate
- Vehicles move toward parking areas
- Vehicles do not dominate the central zone
- Service/delivery movement should be controlled and practical
5.3 Accessibility
Paths should be buildable with smooth, safe access where possible.
Requirements
- Minimize trip hazards
- Ensure reasonable width for main paths
- Ensure toilet and cafe access is practical for all users
6. Landscape and Public Realm
Requirements
- Central fountain/plaza to have a defined finished surface
- Landscape around paths and buildings where practical
- Shade provision around the plaza and cafe
- Opportunity for seating around the center
- Optional planting at the perimeter and between housing units
Intent
The compound should feel like a coherent, lived-in community environment rather than a parking-led estate.
7. Utility and Service Considerations
The builder should make reasonable allowance for:
- water supply
- drainage
- toilet waste routing
- electrical service to cafe and houses
- external lighting
- fountain service requirements
- stormwater management
Public toilets and cafe services should be planned together where possible to simplify construction.
8. Construction Priorities
Phase 1
- Site setting out
- Boundary wall/fence
- Main gate/security access
- Central fountain/plaza
- Cafe and toilet block
- One section of housing
- One car park
Phase 2
- Remaining detached houses
- Manor house
- Second car park
- Path upgrades
- Landscape works
Phase 3
- Final finishes
- Extended external works
- Additional compound enhancements if required
9. Builder Deliverables
The builder should prepare or confirm:
- site set-out plan
- foundation strategy
- drainage layout
- access and path layout
- parking layout
- wall/gate details
- building footprints for cafe, toilet block, houses, and manor house
- phased construction sequence
- costed breakdown if requested
10. Simple Spatial Order for Setting Out
Use this order when marking out the site:
- Fix the compound center point
- Mark the fountain and plaza
- Mark the cafe
- Mark the toilet block
- Mark the residential ring
- Mark the manor house
- Mark the car parks
- Mark the perimeter wall and gate
- Mark the pedestrian paths
- Confirm vehicle access stays at the edge
11. Planning Statement
The project is a gated radial residential compound centered on a public plaza and fountain, with supporting cafe and toilet facilities, inward-facing detached houses, a larger manor house, dual perimeter car parks, and secure boundary access.
12. Builder Note
This is a concept brief, not yet a full technical drawing package. Final dimensions, structure, drainage, utilities, and compliance details must be resolved in measured plans before construction.
