The quiet cost of choosing a cheap garden annexe

Why all-inclusive isn’t just for your summer holidays

Not all garden annexes are created equal. While some providers advertise low starting prices, what they often don’t mention are the essential services missing from the quote. Before you commit to what seems like a bargain, it’s crucial to understand what is and what isn’t included.

As the UK’s leading annexe specialist, we’ve seen countless cases where families initially opted for cheaper providers, only to face unexpected costs, delays, and stress when key elements like annexe planning permission, groundwork, or utility connections were left out.

What to look out for from a low-cost garden annexe quote

If you’re comparing providers, watch out for quotes that seem too good to be true. You may find that:

  • Planning permission and building regulation support are not included
  • Utility connections like water, electricity, and sewage are treated as extras
  • Groundworks and foundations aren’t covered in the base price
  • Heating, electrics, and plumbing are left for you to organise
  • Lower-grade materials and poor insulation reduce energy efficiency
  • There is no project management and you’re expected to coordinate the build yourself

These hidden costs can add thousands to your project and create significant delays and stress during an already emotionally loaded time. It’s vital to understand the full cost breakdown of planning, building and maintaining a garden annexe.

Annexes designed for multi-generational living

More families are choosing multi-generational living, a smart and compassionate solution that brings relatives closer while maintaining independence. Whether you’re creating space for elderly parents, grown-up children, or downsizing for yourself, a garden annexe must be private, comfortable, and long-lasting.

We tailor every iHus annexe to suit individual needs, ensuring the space is accessible, energy-efficient, and built to residential standards. From en-suite bathrooms to integrated kitchens and wide doorways, every detail is considered.

 

What questions to ask before you buy a garden annexe

If you’re exploring options for a garden annexe, make sure to ask:

  • Does the quote include planning permission and council approvals?
  • Are utility connections and groundworks included in the price?
  • Who manages the build? You, or a dedicated project manager?
  • Are the materials energy-efficient and suitable for year-round use?
  • Is there a warranty or ongoing customer support?

These questions can reveal the difference between a low-cost shell and a fully functioning home.
