Exploring Manchester's House Extension Costs

xpanding your home in Manchester can be an exciting project, but it's essential to understand the costs involved. Let's break down the expenses for basic single and double-story extensions .

Basic Single-Story Extension (4m to 5m)

For a single-story extension, expect a build cost of approximately £35,000. Additional professional fees, including architect, planning application, building regulations, and structural engineer, add up to 12-15% of the build cost. VAT contributes around £6,200. Roughly, each square meter adds about £1,500 to the total, with costs varying in London and the South East, ranging from £1,800 to £2,200 per m². Combining these, a single-story extension totals about £45,500.

Basic Double-Story Extension

Scaling up to a double-story extension increases the build cost to around £50,000. Similarly, professional fees and VAT apply, bringing the total estimate to about £65,750.

Additional Expenses to Consider

These estimates assume straightforward construction. However, additional features like bathrooms (£5,000), kitchens (£10,000 for mid-range), and sliding or folding doors (£5,000 for 2.5m width opening) can increase costs. Luxurious finishes such as tiles and bespoke joinery come with additional expenses.

Factors Affecting Costs

Several factors can influence costs:

  • Soil type and ground conditions may necessitate specific construction techniques.
  • Limited access can pose challenges for equipment and tool transportation.
  • Structural modifications, like removing walls, might require steelwork.
  • Relocating pipework, gas meters, or drainage facilities adds extra expenses.

Ensuring Quality Construction

To ensure quality construction, hiring a competent architect is crucial. Architects can:

  • Assist in realizing your vision for the extension.
  • Help manage costs effectively and offer budget-friendly suggestions.
  • Obtain quotes from builders and compile tender lists.
  • Oversee builders' work and ensure compliance with agreements.

Cost-Saving Tips

Consider doing some work yourself and leverage resources like 'Building Supplies Online' for trade prices on supplies like tiles, kitchen fittings, and flooring. Additionally, contractors and designers often access trade discounts, so it's worth exploring various options to save money.

Expanding your home in Manchester can be a rewarding endeavor with careful planning, budgeting, and professional guidance.
