The Land Search Process
Finding suitable land for your self-build project requires a systematic approach and patience. The average self-builder spends 6-12 months searching before finding the right plot.
Where to Look for Land
- Specialist Plot Websites: PlotSearch, PlotBrowser, and Rightmove's land section
- Estate Agents: Register with local agents and request land alerts
- Auctions: Property auctions often include land with or without planning permission
- Local Authority Registers: Self-build registers maintained by councils
- Direct Approaches: Contacting landowners about potential plot divisions
- Word of Mouth: Informing local builders, architects, and planning consultants of your search
Types of Plots Available
- Greenfield Sites: Previously undeveloped land, often in rural areas
- Brownfield Sites: Previously developed land that may require remediation
- Garden Plots: Subdivided gardens from existing properties
- Replacement Dwellings: Sites with existing buildings for demolition
- Serviced Plots: Land with utilities and access already established
- Custom Build Sites: Developer-led opportunities with infrastructure in place
Essential Plot Evaluation Criteria
When assessing potential plots, consider these key factors to avoid costly mistakes:
Location Assessment
- Proximity to amenities (schools, shops, healthcare)
- Transport links and commuting times
- Local environment and noise levels
- Community feel and neighbourhood
- Future development plans for the area
Site Characteristics
- Size and shape of the plot
- Topography and gradient
- Soil conditions and ground stability
- Drainage and flood risk
- Orientation and solar access
Legal Considerations
- Planning permission status
- Title deeds and boundary clarity
- Rights of way and easements
- Restrictive covenants
- Ransom strips or access issues
Infrastructure & Services
- Availability of utilities (water, electricity, gas)
- Sewerage and drainage connections
- Broadband and telecommunications
- Access road quality and ownership
- Distance to connection points
Expert Tip:
Always budget for a comprehensive site investigation before purchase. The £2,000-£5,000 cost could save you tens of thousands in unexpected groundwork expenses later.
Planning Permission Considerations
Understanding the planning status of a plot is crucial for assessing its viability:
Types of Planning Permission
- Outline Planning Permission (OPP): Establishes the principle of development but requires further detailed applications
- Detailed/Full Planning Permission: Comprehensive approval for specific designs and layouts
- Permission in Principle (PiP): Newer two-stage process separating land use decision from technical details
- Self-Build Exception Sites: Special provisions for self-build homes outside normal development boundaries
Assessing Planning Potential
For plots without existing permission:
- Review the Local Plan and development policies
- Check for settlement boundaries and designated areas
- Research precedents for similar developments nearby
- Consider pre-application consultation with planning officers
- Assess alignment with national planning policy
Planning Conditions and Constraints
Even with permission, be aware of potential limitations:
- Design restrictions and material specifications
- Time limits for implementation (typically 3 years)
- Section 106 agreements and Community Infrastructure Levy
- Ecological surveys and mitigation requirements
- Affordable housing contributions on larger plots
Site Access and Infrastructure
Access Considerations
Access issues can make or break a self-build project:
- Legal Access: Ensure the plot has legal right of access from a public highway
- Physical Access: Assess whether construction vehicles can reach the site
- Visibility Splays: Highway authority requirements for safe entry/exit
- Shared Access: Understand maintenance responsibilities and restrictions
- Temporary Access: Options for construction phase if permanent access is limited
Utility Connections
The cost and feasibility of connecting to services can significantly impact your budget:
Utility | Key Considerations | Typical Connection Costs |
---|---|---|
Water | Distance to mains, pressure requirements, temporary supply | £1,500-£5,000 |
Electricity | Capacity, distance to grid, transformer requirements | £3,000-£15,000+ |
Gas | Availability in area, distance to connection point | £2,000-£8,000 |
Sewerage | Mains availability, fall requirements, alternative options | £5,000-£15,000 |
Broadband | Fibre availability, rural connectivity options | £500-£5,000 |
Off-Grid Alternatives
For remote plots, consider these self-sufficient options:
- Water: Borehole, well, or rainwater harvesting systems
- Electricity: Solar PV, wind turbines, or hybrid systems with battery storage
- Heating: Ground/air source heat pumps, biomass boilers
- Sewage: Septic tanks, treatment plants, or composting toilets
- Communications: Satellite broadband, 4G/5G routers
Ground Conditions and Site Surveys
Essential Site Investigations
Understanding what lies beneath the surface is crucial:
- Topographical Survey: Accurate mapping of levels and features (£800-£1,500)
- Soil Investigation: Trial pits or boreholes to assess ground conditions (£1,500-£3,000)
- Contamination Assessment: Testing for pollutants on brownfield sites (£2,000-£5,000)
- Flood Risk Assessment: Mandatory for sites in flood zones (£1,000-£3,000)
- Tree Survey: Assessment of trees affecting development (£500-£1,200)
Common Ground Issues
Be alert to these potential problems:
- Clay Soils: Risk of shrinkage and heave affecting foundations
- Made Ground: Previously filled land requiring enhanced foundations
- High Water Table: Drainage challenges and waterproofing requirements
- Rock Formations: Excavation difficulties and increased costs
- Mining Areas: Subsidence risks and coal mining searches
- Contamination: Industrial pollutants requiring remediation
Warning Signs to Watch For:
- Unusual vegetation patterns suggesting drainage issues
- Cracks or subsidence in nearby structures
- Evidence of previous industrial use
- Waterlogging or standing water after rainfall
- Unusual dips or mounds in the terrain
Financial Evaluation and Making an Offer
Plot Value Assessment
Determining a fair price for land:
- Residual Valuation: End value minus build costs and profit
- Comparable Evidence: Similar plots sold in the area
- Plot-to-House Ratio: Typically 25-40% of completed property value
- Regional Variations: Significant differences across the UK
- Planning Status Premium: Higher values for plots with permission
Hidden Costs to Consider
Beyond the purchase price, budget for these additional expenses:
- Legal Fees: £1,500-£3,000 for land purchase
- Stamp Duty Land Tax: Progressive rates on land value
- Survey Costs: £3,000-£10,000 for comprehensive investigations
- Site Clearance: £5,000-£20,000 depending on vegetation and structures
- Temporary Services: Water and power during construction
- Access Creation: Temporary and permanent driveway costs
- Planning Fees: Application and discharge of conditions
Making a Successful Offer
Strategies for securing your chosen plot:
- Conditional Offers: Subject to planning, surveys, or finance
- Option Agreements: Secure first right to purchase
- Quick Decision Making: Be prepared to move fast on good plots
- Professional Support: Use experienced solicitors and surveyors
- Flexible Terms: Consider staged payments or extended completion dates
