What Investment Model Do We Use That Could Double 1 Million Pound in 18 Months?

Investors regularly ask us what is the best way to double 1 million pound. When the objective is meaningful capital growth rather than incremental returns.

This article provides a clear, experience-led overview of how Planning Gain Investments have played that role within our own strategy, and how the model has been refined over time through practical execution.

This is not a promise, forecast, or guarantee. It is a transparent explanation of what has worked for us historically, what we learned along the way, and how those lessons now inform the way Starfortis structures property joint ventures for high-net-worth investors looking to double 1 million pound within an 18 month timeframe.

Why Planning Gain Investments can double 1 million pound

Planning Gain Investments focus on acquiring property or land at an attractive entry point, securing planning consent to materially enhance value, and exiting at the uplifted valuation.

Value creation is driven by planning expertise, disciplined underwriting, and execution rather than reliance on general market appreciation.

When structured correctly, planning gain can produce asymmetric outcomes: the downside is supported by a tangible underlying asset, while the upside is driven by planning approval and improved use.

Planning Gain Investments Explained

A planning gain investment typically involves:

• Acquiring land or buildings with planning potential
• Securing planning consent for a higher-value use, often residential
• Revaluing the asset at its enhanced market value
• Exiting via sale, refinance, or internal capital restructuring

In certain scenarios, this approach has allowed capital to be recycled efficiently within defined timeframes, which is why it has become a core component of our investment model.

Previous Planning Gain Investments

Investment 1 – Strategic Land with Large-Scale Planning

• Purchase price: £1.0m
• Planning achieved: 175 residential apartments
• Post-planning valuation: £2.1m (c. £12k per unit)
• Planning costs: £450k
• Gross margin: £650k
• Return on capital employed (ROCE): 144%

Investment 2 – Strategic Land Acquisition

• Purchase price: £1.2m
• Planning achieved: 195 residential apartments
• Post-planning valuation: £2.4m (c. £12.5k per unit)
• Planning costs: £500k
• Gross margin: £700k
• ROCE: 140%

These projects demonstrated the scale of value that planning uplift can create and validated planning gain as a repeatable value-creation strategy when appropriately structured to double 1 million pound within an 18 month time-frame.

Key Early Lessons

• Larger schemes typically require longer planning timelines, often around 18 months or more.
• Exit liquidity can be more concentrated, particularly in Tier 2 and Tier 3 regional cities.
• Land-led exits generally attract more conservative lending, with typical exit LTVs around 50%.
• High-quality advisory and agency support is essential on larger land transactions.

These are not weaknesses in the strategy, but variables that must be actively managed through structure, timing, and diversification.

Refining the Model: Planning Gain on Existing Buildings

We subsequently refined our approach by focusing on commercial-to-residential planning gain using existing buildings rather than large land parcels.

Investment 3 – Mid-Scale Conversion

• Purchase price: £1.2m
• Planning achieved: 35 apartments
• Post-planning valuation: £1.75m
• Planning costs: £255k
• Gross margin: £295k
• ROCE: 116%

Investment 4 – Smaller Commercial Asset

• Purchase price: £255k
• Planning achieved: 15 apartments
• Post-planning valuation: £450k
• Planning costs: £100k
• Gross margin: £145k
• ROCE: 290%

What Changed This Time

• Planning timelines shortened to approximately 6–9 months.
• Buyer demand increased due to smaller, more accessible deal sizes.
• Refinance exits became more viable, with senior and mezzanine lenders supporting higher leverage in certain cases.
• Deal flow improved through a broader pool of off-market opportunities.

Downside Protection

What Happens If Planning Is Not Achieved?

Planning risk is real, but it can be managed.

• Focusing on established residential locations
• Targeting assets with strong precedent for change of use
• Applying conservative assumptions on unit density and valuation
• Undertaking pre-application discussions and feasibility studies prior to submission

If planning is delayed or refused, options include appeal, resubmission with improved design, or disposal of the underlying commercial asset.

Diversification across multiple projects further mitigates single-asset planning risk.

What If an Exit Is Delayed?

Our preferred route is to exit planning gain investors internally using our own debt facilities following a new Red Book valuation.

• Senior or stretched-senior refinancing
• Senior and mezzanine structures
• Open-market disposal via specialist development agents

Maintaining multiple exit routes is a core part of our risk framework.

How the Model Evolved Further

Diversification

We favour multiple smaller allocations rather than concentrated exposure to a single large project. This enhances downside protection and capital resilience.

Liquidity Discipline

Capital is not deployed all at once. Staggered drawdowns and retained liquidity provide flexibility if conditions change.

Defined Exit Path

Our objective is to control the development lifecycle, enabling us to refinance planning gain investors internally once planning is secured.

What We Are Looking For

We are not seeking a single £1m investor. Our preference is to work with a small group of experienced high-net-worth investors contributing approximately £200k each.

• Net worth in excess of £2–3 million
• Experience with property or alternative investments
• This allocation forming part of a diversified portfolio

How the Structure Works

• Four concurrent planning gain projects
• Capital allocation of £250k per project
• Staggered deployment with monthly drawdowns
• Maximum capital allocation typically capped at c.80% at any point
• Target planning timeframe of approximately 9 months

Capital recycling across multiple projects allows gains to compound over the investment term.

While outcomes cannot be guaranteed, this structure has historically created the conditions to allow Starfortis to double 1 million pound within 18 months.

Final Thought: On How To Double 1 Million Pound in 18 months

Planning Gain Investments require experience, discipline, and robust risk management. When executed well, they can form a compelling component of a high-net-worth investor’s wider portfolio.
