Residential Development

What residential development includes#

Residential development may include:

• apartments for sale
• houses or townhouses for sale
• build-to-rent housing
• rehabilitation and conversion of existing buildings
• co-living or other managed residential concepts
• mixed tenure projects
• affordable or price-controlled housing
• residential components of mixed-use developments
• subdivisions followed by individual plot or unit sales
• and phased masterplanned communities

These models do not have identical planning, finance, tax, operational or exit characteristics. A project for individual unit sales requires a different legal and cash-flow structure from a building intended to be retained and leased. A managed residential product may also require services, staffing, common facilities and operator arrangements that would not exist in an ordinary condominium.

Define the customer before the design#

The residential brief should identify the intended customer using evidence rather than broad labels.

Relevant questions include:

• Is the buyer or tenant local, national or international?
• Is the property intended as a principal home, second home, investment or managed accommodation?
• What household size is being targeted?
• Which unit sizes are actually absorbed in the micro-location?
• Which price or rent bands have sufficient depth?
• Are parking and storage essential to the customer?
• Which outdoor areas, amenities and services create value?
• How sensitive is demand to mortgage availability or interest rates?
• Are sales seasonal?
• Is the exit dependent on one narrow buyer group?

The unit mix should follow the market evidence and the project economics. It should not be selected solely because a particular typology produces the highest theoretical price per square metre. Smaller units may achieve higher rates per square metre but can require more kitchens, bathrooms, circulation, service risers, parking spaces, meters and marketing activity. Larger units may sell more slowly or require a higher specification. The correct mix is a balance between demand, efficiency, planning, cost and absorption.

Planning and use classification#

Confirm the planning position before treating a residential concept as viable.

The review should establish:

• the applicable municipal and territorial plans
• land classification and permitted use
• gross construction area and implantation area
• density, height and number of floors
• setbacks and building alignments
• parking requirements
• private and public open-space requirements
• infrastructure and urbanisation obligations
• protected trees, heritage, archaeology, RAN, REN, coastal, water or environmental constraints
• legal access and road capacity
• and whether an existing building has a lawful residential use and lawful antecedents

The registry description, tax record or current physical occupation does not by itself establish a right to develop or use the property for the proposed residential scheme. Where the planning position is uncertain, a prior information request may be used to test defined parameters before the complete design and licensing package is prepared. The legally applicable procedure must be confirmed for the specific operation, municipality and submission date. Licence, prior communication, exemption and other urban-planning routes should not be described as interchangeable choices.

Product and design decisions#

The residential design should coordinate:

• orientation, daylight and views
• privacy and overlooking
• internal layouts and furniture zones
• balconies, terraces, gardens and roof areas
• accessibility and adaptable units
• vertical and horizontal circulation
• fire strategy and evacuation
• acoustic separation
• energy performance and building systems
• water, drainage, electricity, telecoms and metering
• refuse and recycling areas
• bicycle and mobility infrastructure
• parking access and manoeuvring
• storage
• technical rooms
• concierge, security or amenity space where relevant
• landscape and public-realm interfaces
• and maintenance access throughout the building

Design decisions should be tested against both customer value and lifecycle cost. An amenity may improve sales, but it may also reduce saleable area, increase construction cost and create continuing condominium charges. A façade or landscape solution may be visually strong but difficult to maintain. A mechanical system may improve energy performance but require specialist operation and replacement reserves.

Area efficiency#

The financial model must distinguish between different area concepts.

At minimum, record:

• site area
• implantation area
• gross construction area
• above-ground and below-ground area
• private unit area
• internal saleable or lettable area
• balconies, terraces and gardens
• common circulation
• shared amenities
• parking and storage
• plant and technical areas
• and any public or infrastructure areas to be transferred or constructed

The planning area, construction area, sale contract area and valuation area may not be identical. Every financial assumption should identify which area definition is being used.

Revenue model#

Asking prices are not evidence of completed sales values. For mixed sale-and-hold projects, separate each revenue stream and confirm how common costs, debt repayment and unit releases will operate.

Finance and cash-flow profile#

Residential development is exposed to a timing gap between early expenditure and eventual unit completions or stabilised rental income.

The cash flow should show:

• land acquisition and taxes
• design and surveys
• municipal and infrastructure costs
• construction expenditure
• lender and monitoring costs
• interest and hedging where applicable
• marketing and sales costs
• deposits and staged buyer payments
• debt drawdowns
• unit release prices
• loan repayment
• retention and defect liabilities
• and investor distributions

Buyer deposits should not be treated as unrestricted funding without reviewing the sale contract, lender controls, refund exposure, consumer obligations and delivery milestones.

Sales, contracts and consumer-facing information#

Marketing material, plans, renders, area statements and specifications should be controlled as transaction documents. Inconsistent descriptions can create buyer claims, finance problems and completion disputes.

Property horizontal and completion#

Where units will be separately owned, the project must coordinate the approved and as-built design with the proposed horizontal-property structure.

Residential feasibility inputs#
