Bungalow-Specific Renovation Considerations
Bungalows have unique characteristics that affect renovation costs. The larger roof area relative to floor space means roof repairs, insulation, and re-covering costs more proportionally. However, single-storey access eliminates the need for scaffolding on upper floors and simplifies many trades.
Many bungalows have flat-roofed sections over extensions or porches. These often leak and require replacement, typically costing £80-£120 per square metre for a modern flat roof system.
Common Bungalow Renovation Projects
- Kitchen renovation: Opening up to dining areas, modern units (£8,000-£25,000)
- Bathroom modernisation: Walk-in showers, accessible designs (£4,000-£12,000)
- Roof replacement: Larger areas mean higher costs (£6,000-£15,000)
- Loft insulation: Large roof voids need thorough insulation (£1,500-£3,500)
- Window replacement: Often numerous windows throughout (£6,000-£14,000)
- Heating upgrade: Efficient systems for single-storey layouts (£4,000-£9,000)
- Garage conversion: Reusing an attached or integral garage for living space
Extension Options for Bungalows
Bungalows often sit on larger plots than equivalent houses, making extensions more achievable. Popular options include rear extensions to create open-plan living, side extensions to add bedrooms or utility rooms, and wraparound extensions that combine both.
Converting a bungalow to a chalet-style property by raising the roof and adding first-floor rooms is a major project but can nearly double the living space. This typically costs £60,000-£100,000 depending on the extent of work required.
What Affects Bungalow Renovation Costs?
- Property size: Square footage directly impacts material and labour costs
- Age and condition: 1960s bungalows often need more updating than 1980s builds
- Roof condition: Larger roofs mean higher repair/replacement costs
- Layout changes: Creating open-plan requires structural work
- Location: Regional labour rate variations apply as with any property
- Accessibility requirements: Level access and wet rooms add specialist costs

How We Calculate Costs
RenoCost estimates are calculated from published UK cost benchmarks and RenoCost's documented per-module cost assumptions. The model adjusts these assumptions using the property characteristics, selected renovation scope, finish level and broad postcode-based pricing region, then presents a low, mid and high planning range.
- Published UK benchmarks — macro reference points for construction costs and materials and labour trends, used to sense-check RenoCost's own assumptions.
- RenoCost's per-module assumptions — cost and duration assumptions for each renovation module, reviewed and updated periodically by the RenoCost team.
- Estimate ranges — low, mid and high bands set to reflect the realistic spread between competitive and premium specifications, rather than a single fixed price.
Data confidence note
Completed calculator estimates are used to produce anonymous renovation-planning insights. They are not contractor quotations, invoices or confirmed final project costs. RenoCost estimates are intended for initial planning and budgeting. Property condition, specification, access, contractor availability and site-specific requirements can change the final cost. Always obtain detailed written quotations before committing to a project.
Regional adjustments are applied based on postcode area to reflect broad differences in local labour and material rates. See our Method Glossary for definitions of the terms used here.
