Factors Affecting Kitchen Extension Costs
Many elements influence the total price tag for adding a kitchen extension. Being aware of these key considerations can help you plan and budget accordingly:
- Size – The larger the extension, the more it will cost. Even a few extra square metres can add thousands.
- Foundations – Extending onto a concrete base is simpler than digging new foundations, which adds significant expense.
- Roof – A flat roof is usually cheaper than a pitched alternative, which requires added labour and materials.
- Windows – More windows mean higher costs, especially if adding glazed doors or skylights. Opt for standard sizes.
- Electrics – Rewiring, adding sockets, and installing new lighting add to the bill. Manage costs with LED bulbs.
- Plumbing – Moving appliances and sinks plus installing waste pipes and water lines impact the budget.
- Flooring – Tile and stone are pricier than laminate or vinyl. Look at remnant deals for bargains.
- Appliances – Integrated or built-in appliances are convenient but cost more than freestanding.
Carefully thinking through your must-haves and making some thrifty choices where possible will help control expenses. Getting quotes from several builders is also wise to find the best value.
Budgeting For Your Kitchen Extension
Setting a realistic budget is key when adding a kitchen extension to your home. With careful planning, you can avoid cost overruns and keep the project affordable.
As a general guideline, a basic single-storey extension with a flat roof can be done for £15,000 – £25,000. More complex projects with larger dimensions, pitched roofs, and higher-end finishes can cost £2,000 – £3,000 per square metre.
To determine a ballpark figure, get quotes from builders outlining all projected costs. Be sure to factor in:
- Construction materials
- Labour and trade fees
- Architect and planning permission expenses
- Contingency funds for unforeseen costs
You may be able to trim expenses by supplying your appliances or doing basic prep work like demolishing old walls. Opting for more affordable finishes like laminate over stone can also help control costs.
Securing financing in advance is prudent to cover all projected amounts. Budget carefully and you can successfully transform your kitchen within your financial means.
Financing Your Kitchen Extension
Funding a kitchen extension can be daunting, but with the right approach, you can secure the money needed without breaking the bank.
If you have equity in your home, a home equity loan or line of credit is an option to tap into cash for the project. The interest rates are usually lower than other financing options.
Compare rates on personal loans from banks and credit unions. This lump sum can give you flexibility in how the funds are used.
0% interest credit cards offer 12-18 months to pay for the work interest-free. Just be sure to pay off the balance before the promotional period ends.
Remortgaging your home is another route to generate funds by increasing your existing mortgage. The lower interest rate could save money long-term.
Government schemes like the Green Homes Grant provide vouchers towards energy-efficient improvements like insulation, potentially lowering your overall costs.
Every financial situation is different. With research into the best financing options for your needs, you can make your dream kitchen extension a reality.
