Single vs Double Storey Extensions: Pros & Cons (Lincoln Homeowner Guide)

If you're planning to extend your home in Lincoln, one of the biggest decisions you'll face is whether to go for a single storey extension or a double storey extension. Both options can transform your property, but they come with different costs, benefits, and planning considerations.

In this guide, we break down the pros and cons of each to help you decide what’s right for your home, budget, and long-term goals.

What is a Single Storey Extension?

A single storey extension adds extra space on one level—usually at the rear or side of your property. In Lincoln, these are commonly used for:

• Kitchen extensions

• Open-plan living areas

• Dining rooms

• Home offices

Pros of Single Storey Extensions

1. More Affordable

Single storey extensions are typically cheaper than double storey builds due to less structural work and simpler design.

2. Faster Build Time

With fewer complexities, construction is usually quicker—meaning less disruption to your daily life.

3. Easier Planning Approval

Many single storey extensions fall under permitted development rights, making planning permission easier (though not always guaranteed in Lincoln).

4. Great for Open-Plan Living

Perfect for modern lifestyles, allowing you to create large, light-filled kitchen and living spaces.

Cons of Single Storey Extensions

1. Limited Space Gain

You’re only expanding on one level, which may not be enough for growing families.

2. Loss of Garden Space

Extending outward reduces your outdoor area—something to consider for Lincoln properties with smaller plots.

3. Lower Value Increase (Compared to Double Storey)

While still valuable, the return on investment is often less than a double storey extension.

What is a Double Storey Extension?

A double storey extension adds space across two floors—typically expanding both your ground floor and adding bedrooms or bathrooms upstairs.

Pros of Double Storey Extensions

1. Maximises Space

You effectively double your added floor area without taking up extra garden space beyond the footprint.

2. Better Value for Money (Long-Term)

Although more expensive upfront, the cost per square metre is often lower compared to building two separate single storey extensions later.

3. Significant Property Value Increase

Adding bedrooms and bathrooms can dramatically boost your home’s value—especially in areas like Lincoln where family homes are in demand.

4. Ideal for Growing Families

Provides flexibility for additional bedrooms, en-suites, or even a home office upstairs.

Cons of Double Storey Extensions

1. Higher Initial Cost

More materials, structural work, and design complexity mean a larger upfront investment.

2. More Complex Planning Process

Double storey extensions in Lincoln are more likely to require full planning permission and must meet stricter guidelines (e.g., overlooking neighbours, height restrictions).

3. Longer Build Time

Expect a longer construction period and potentially more disruption.

4. Structural Considerations

Your existing home may need strengthening to support the additional floor.

 Key Considerations for Lincoln Homeowners

When deciding between single and double storey extensions in Lincoln, think about:

• Your budget – What can you realistically invest?

• Your long-term needs – Will you outgrow the space quickly?

• Plot size – Do you have enough outdoor space to sacrifice?

• Planning constraints – Local regulations and neighbouring properties

• Property type – Victorian, semi-detached, or detached homes all have different limitations

There’s no one-size-fits-all answer. The right choice depends on your lifestyle, budget, and future plans. For many homeowners in Lincoln, the decision comes down to whether you need more living space now or more total space for the future.

If you’re unsure, getting professional advice early on can save you time, money, and costly mistakes later.
