An oak framed garage with a room above is more than just practical—it’s a stylish investment that adds value, character, and versatility to your property. But before beginning construction, understanding the cost implications is crucial. From materials and labor to planning permissions and finishing details, this guide breaks down what to expect financially when working on such a project.
- Initial Planning and Design Costs
The first step is design, and whether you go custom or choose a pre-designed kit, costs vary. Custom architectural plans tailored to your property can range from £1,500 to £5,000 depending on complexity. Pre-drawn plans can lower this cost significantly but may offer less flexibility.
Planning permission may also be required, especially if the structure exceeds certain dimensions or is located in a conservation area. Application fees in the UK typically range from £200 to £500, excluding consultant fees if professional guidance is needed.
- Material Costs: Why Oak Isn’t Cheap
Oak is a premium hardwood, valued for its strength, longevity, and aesthetic appeal. For the frame alone, expect to pay £250–£400 per square meter. A typical double garage with a room above (around 6m x 6m footprint) could run between £15,000 and £25,000 just for the oak frame.
Other materials such as roofing, insulation, cladding, and windows will add to the cost. Tile or slate roofing can range from £50 to £100 per square meter, while high-quality insulation and double-glazed windows can quickly add another £5,000–£10,000.
- Construction and Labor Costs
Labor is a major portion of your budget. If you hire a specialist oak frame construction company, you’re looking at £150–£250 per day per worker. Full construction, including the foundation, frame assembly, roofing, and interior room completion, may take 6–12 weeks depending on weather, site access, and scope.
Total build costs including labor and materials often fall between £40,000 and £80,000 for a high-quality oak framed garage with an upper room. DIY or partial self-build options can cut these costs, but only if you’re confident in managing a complex build.
- Interior Finish and Utility Installations
The upper room could be used as an office, guest room, or studio—but fitting it out adds to the price. Plastering, flooring, heating, and electrical work could range from £5,000 to £15,000 depending on finish and quality. Add more if plumbing or a bathroom is required.
Electric connections, lighting, and heating solutions (like underfloor heating or radiators) should be budgeted early. Consider sustainable add-ons like solar panels if future energy savings are a priority.
- Long-Term Value and Maintenance
While the initial outlay is significant, oak framed buildings hold value well. A well-designed garage with usable upper space can increase property value by 10–15%. Oak also requires minimal maintenance—just occasional treatments to retain color or prevent weathering—making it a long-term, low-maintenance asset.
Conclusion:
Building an oak framed garage with room above is a sizable investment, typically ranging from £40,000 to £90,000 depending on design, size, finish, and location. However, it offers excellent return on investment through added functionality, aesthetics, and property value. Planning ahead, understanding cost breakdowns, and working with experienced professionals can ensure a smoother, more cost-effective build.
