What Is Mixed-Use Development Finance?
**Mixed-use development finance** funds projects that combine two or more property uses within a single scheme. The most common configuration is **residential units above commercial space** - flats over shops, offices, or restaurants - but mixed-use can also include combinations of retail, office, leisure, healthcare, and residential.
Mixed-use developments are a staple of UK town centres and high streets. They provide housing above active ground floor uses, contributing to vibrant, sustainable communities. For developers, they offer diversified income streams and the ability to unlock value from sites that may not work for a single use.
However, mixed-use projects present unique financing challenges. The residential and commercial elements are valued differently, attract different occupiers and buyers, and require different exit strategies. Understanding how lenders approach mixed-use schemes is essential for structuring a viable project.
Why Mixed-Use Is Different
A purely residential [development finance](/services/development-finance) facility is relatively straightforward - all units are valued on comparable sales evidence and sold to individual buyers. A mixed-use scheme introduces several complications:
- Dual valuation methodology - residential units valued on comparables, commercial on investment yield
- Different exit timescales - residential may sell quickly while commercial lettings take longer
- Complex lease structures - commercial leases, service charges, and management arrangements
- Higher holding costs - if commercial space takes longer to let or sell
- Planning complexity - mixed-use schemes may face more scrutiny from planning authorities
- Building design challenges - noise and odour separation between commercial and residential
**Key Takeaway:** Mixed-use development is not simply residential development with a shop underneath. Each use brings its own valuation methodology, tenant profile, exit strategy, and risk factors. Your project appraisal must address each element separately and together.
Common Mixed-Use Configurations
Retail Below, Residential Above
The classic UK high street configuration. Ground floor retail units with residential flats on upper floors. Works well in established town centres with retail demand.
Office Below, Residential Above
Less common but growing in popularity, particularly in edge-of-centre locations. Office units may be let to local businesses or used as serviced office space.
Leisure Below, Residential Above
Restaurants, cafes, gyms, or bars on the ground floor with residential above. These can be attractive but raise noise and odour management issues that must be addressed in the design.
Residential with Community Uses
Schemes that include community facilities such as a GP surgery, nursery, or community hall alongside residential development. Often driven by planning policy requirements.
Multi-Storey Mixed-Use
Larger schemes with commercial on lower floors and multiple residential floors above. Common in urban centres and often associated with higher-density development.
How Lenders Assess Mixed-Use Schemes
GDV Calculation
The [Gross Development Value](/knowledge-hub/gross-development-value-lender-assessment) of a mixed-use scheme is calculated by combining:
**Residential GDV**: Valued on **comparable sales evidence** - what similar flats have sold for in the area. The standard approach used for all residential development.
**Commercial GDV**: Valued on an **investment yield basis**:
Commercial Value = Annual Rental Income / Yield
For example, a ground floor retail unit let at £25,000 per annum in an area where similar investments trade at a 6% yield would be valued at approximately £416,000.
The combined GDV is the sum of residential and commercial values.
Lender Appetite by Commercial Proportion
Lenders' appetite for mixed-use depends heavily on the **proportion of commercial space**:
| Commercial % of GDV | Lender Appetite |
|---|---|
| Below 20% | Strong - most development lenders comfortable |
| 20-35% | Good - mainstream specialist lenders |
| 35-50% | Moderate - selective lenders |
| Above 50% | Limited - specialist commercial lenders only |
Schemes where commercial represents less than 20-25% of GDV are generally treated as residential developments with ancillary commercial, attracting the widest lender choice and best pricing.
Key Lender Concerns
When assessing mixed-use applications, lenders focus on:
- Residential sales evidence - are the flat values well supported?
- Commercial letting demand - is there occupier demand for the commercial space?
- Rental evidence - what do similar commercial units let for in the area?
- Investment yield - is the assumed yield realistic for the location and property type?
- Commercial exit - will the commercial space sell to an investor, or will the developer retain it?
- Separation - are the residential and commercial elements properly separated (access, services, sound, odour)?
- Service charge - is the proposed service charge structure workable for both uses?
**Key Takeaway:** The more commercial space in your scheme, the more evidence you need to demonstrate letting demand, rental levels, and investor appetite. A pre-let or a letting agent's opinion of rental value significantly strengthens your application.
Structuring the Finance
Single Facility Approach
Most mixed-use development finance is structured as a **single facility** covering both the residential and commercial elements. The lender takes a charge over the entire site and the facility funds all construction costs.
Advantages:
- Simpler legal structure
- One set of legal fees
- Coordinated drawdown process
- Single lender relationship
Split Facility Approach
For larger or more complex schemes, it may be appropriate to use **separate facilities** for the residential and commercial elements:
- Development finance for the residential construction
- Commercial mortgage or commercial development facility for the commercial space
This is less common and involves higher costs but may be necessary where the commercial element is substantial and requires specialist commercial lending expertise.
Mezzanine and Equity
Mixed-use schemes may require a larger equity contribution than purely residential projects because:
- Commercial values are more subjective and potentially more volatile
- Lenders may apply a lower LTGDV to the commercial element
- The blended LTGDV may be lower than for a purely residential scheme
Where equity is constrained, mezzanine finance can bridge the gap, though this increases overall finance costs.
Build Cost Considerations
Additional Costs for Mixed-Use
Mixed-use developments involve additional costs compared to single-use residential:
- Sound insulation between commercial and residential spaces (typically exceeding standard Part E requirements)
- Odour extraction and ventilation for food-related commercial uses
- Separate access and circulation for each use
- Commercial specification for ground floor units (higher ceilings, shopfronts, commercial M&E)
- Separate utility supplies for each use
- Enhanced fire safety provisions (different use categories require careful compartmentation)
- Service charge infrastructure - separate metering, management systems
Typical Additional Cost
The commercial element typically adds **£15,000-£40,000 per commercial unit** to project costs beyond what a purely residential scheme would require, depending on the size and specification of the commercial space.
Planning Considerations
Policy Support
Many local planning authorities **actively encourage mixed-use development** in town centre locations as part of their local plan policies. Mixed-use can:
- Support the vitality of town centres
- Provide housing in sustainable locations
- Make efficient use of brownfield land
- Deliver planning gain (commercial community benefits alongside housing)
Planning Challenges
- Use class changes - ensure the proposed commercial use falls within the correct use class
- Hours of operation - restrictions on commercial operating hours to protect residential amenity
- Delivery and servicing - arrangements for commercial deliveries that do not disturb residents
- Waste management - separate arrangements for residential and commercial waste
- Parking - different parking standards for each use, potentially competing for limited space

Exit Strategies for Mixed-Use
Residential Exit
The residential units are typically sold on the open market to individual buyers or investors. This follows the same process as a purely residential development. Allow adequate time in your programme for sales, and consider [development exit finance](/knowledge-hub/development-exit-finance-guide) if sales extend beyond the development facility term.
Commercial Exit Options
**Option 1: Sell with Tenant in Place** The most valuable exit. Let the commercial space to a tenant on a commercial lease, then sell the investment to a property investor. The value is determined by rental income and yield.
**Option 2: Sell Vacant** Selling vacant commercial space achieves a lower value than selling an occupied investment, but may be the faster route if letting is difficult.
**Option 3: Retain and Refinance** Retain the commercial space as a long-term investment and refinance to a [commercial mortgage](/services/commercial-mortgages) based on rental income. This provides ongoing income and capital appreciation.
**Option 4: Pre-Let** Secure a tenant before or during construction. This provides the strongest exit evidence for lenders and may improve finance terms.
Coordinating the Exits
A key challenge in mixed-use is coordinating the residential and commercial exits. Residential sales may complete within months of practical completion, while commercial lettings can take 6-12 months or longer. Your development finance term should accommodate both timescales, or you should arrange exit finance for the commercial element.
**Key Takeaway:** Plan your commercial exit strategy from the outset. Pre-letting the commercial space before construction removes significant risk and strengthens both your development finance application and your overall project economics.
Choosing a Lender for Mixed-Use
Lenders with strong appetite for mixed-use development include:
- Specialist development lenders such as Shawbrook, Hampshire Trust, and Aldermore - comfortable with mixed-use where residential dominates
- High street banks including Lloyds and NatWest - for larger, well-evidenced schemes
- Challenger banks such as Allica Bank and Investec - flexible on structure and use mix
- Private funds for schemes with higher commercial proportion or more complex structures
Your broker should present the scheme to lenders whose appetite matches the specific use mix, location, and scale of your project. [Contact our team](/contact) to discuss your mixed-use development.

Summary
Mixed-use development finance requires a more nuanced approach than purely residential projects. The dual valuation methodology, different exit strategies for each use, and additional design and construction considerations make these schemes more complex to finance.
However, mixed-use developments offer significant benefits: diversified risk, multiple income streams, and often strong planning policy support. By understanding how lenders assess mixed-use schemes, presenting strong evidence for both residential values and commercial demand, and planning coordinated exit strategies, you can access competitive funding for profitable mixed-use projects.
