Building an Extension in Fleet, Hampshire: A Complete Guide by Primary Construction

If you’re considering a home extension in Fleet, Hampshire or the surrounding towns, you’re not alone. With property prices rising across North East Hampshire, many homeowners are choosing to extend rather than move. At Primary Construction ltd, we are an all‑round building company based in Fleet, offering everything from groundworks and structural builds to supplying and installing windows and doors.

This comprehensive guide walks you through the five key steps to building a successful extension, including costs, budgeting, choosing the right architect and builder, and selecting the best materials for long‑lasting results.

We regularly work in Farnham, Fleet, Church Crookham, Elvetham Heath, Hartley Wintney, Yateley, Farnborough, Crowthorne, Aldershot and Basingstoke, giving us strong local knowledge of planning requirements and building styles.

Step 1: Define Your Extension Goals and Budget

Before any drawings are created or builders contacted, it’s important to be clear on what you want from your extension.

Ask yourself:

• Do you need more living space, a larger kitchen, or an extra bedroom?
• Are you planning a single‑storey or double‑storey extension?
• Will the extension add long‑term value to your Fleet property?

Extension Costs in Fleet, Hampshire

As a general guide:

• Single‑storey extension: £1,800 – £2,500 per m²
• Double‑storey extension: £2,200 – £3,000 per m²

Costs vary depending on ground conditions, access, design complexity, and material choices. Properties in areas like Elvetham Heath or Hartley Wintney may also have additional planning considerations.

💡 Tip: Always include a 10–15% contingency in your budget for unforeseen works.

Step 2: Choosing the Right Architect or Designer

A good architect or architectural designer will turn your ideas into a practical, compliant design.

When choosing an architect for your Fleet extension:

• Look for experience with Hampshire planning authorities
• Ask to see previous extension projects in nearby towns
• Ensure they understand building regulations, not just design

Many extensions in Fleet fall under permitted development, but this isn’t guaranteed. Working with professionals who understand Hart District Council requirements can save time and stress.

At Primary Construction, we regularly collaborate with trusted local architects and can recommend professionals suited to your project size and budget.

Step 3: Selecting the Right Builder in Fleet

Choosing the right builder is one of the most important decisions you’ll make.

What to Look For in a Local Builder

• Proven experience with extensions in Fleet and surrounding areas
• Clear, itemised quotations
• Strong communication and project management
• Ability to handle the full build, from foundations to finishes

Primary Construction ltd is an all‑round building company, meaning you don’t need to juggle multiple trades. We manage:

• Groundworks and foundations
• Brickwork and structural steel
• Roofing and insulation
• Electrical and plumbing coordination
• Windows and doors supply and installation

Using one trusted building company reduces delays, miscommunication, and unexpected costs.

Step 4: Choosing the Right Materials for Your Extension

Material choice affects not just appearance, but durability, energy efficiency, and maintenance.

Common Extension Materials in Hampshire

• Brickwork to match existing Fleet properties
• High‑performance insulation for energy efficiency
• uPVC, aluminium or composite windows and doors
• Bifold, sliding or French doors to maximise light

As a local builder, we understand what works best for homes in Farnham, Fleet, Church Crookham and Yateley, both aesthetically and practically.

Windows and Doors Supply & Installation

We don’t just build extensions – we also supply and install high‑quality windows and doors, ensuring:

• Seamless integration with your extension
• Improved thermal performance
• Enhanced security and kerb appeal

This all‑in‑one approach saves time and ensures consistent quality throughout your project.

Step 5: Managing the Build and Final Finishes

A well‑managed build keeps your project on time and within budget.

During construction, expect:

• Regular progress updates
• Building control inspections
• Clear timelines for each stage

Final stages include:

• Plastering and internal finishes
• Flooring and decorating preparation
• Final installation of windows and doors
• Snagging and handover
