Home Extensions in Aberdeen

In Scotland, a typical house extension depends on the build type, materials, location, and whether you’re adding kitchens, bathrooms or bespoke features. In Aberdeen, costs for a well-built extension by a reputable contractor like Sharpsaw usually start around £45,000, increasing with size and complexity.

In many cases, extending is more cost-effective than moving - especially with rising property prices, legal fees, and moving costs. An extension allows you to create custom space while avoiding the stress of relocating. For many Aberdeen homeowners, it’s a smarter long-term investment.

Typically, the foundations, steelwork, roofing, and kitchen or bathroom fittings are the most expensive parts. Complex groundwork, bespoke glazing, or structural alterations can also drive up costs. 

At Sharpsaw, we provide transparent quotes to help you budget with confidence.

A single-storey rear extension with a simple design (flat roof, minimal structural changes) is often the most affordable. Using existing drainage, avoiding major groundwork, and keeping to standard materials can also reduce costs. 

We help Aberdeen homeowners design extensions that balance function and budget.

Most single-storey extensions take around 10–14 weeks to complete, while double-storey or more complex builds can take up to 16–20 weeks. The timeframe includes groundwork, structure, utilities, and finishing. We always provide a clear project timeline before starting your extension in Aberdeen.

In Scotland, many single-storey extensions fall under permitted development, especially if they are modest in size and don’t extend too close to boundaries. However, you may need planning permission if:

• Your property is listed or in a conservation area

• You plan to build a large or double-storey extension

• Your extension affects neighbours or the street scene

In most cases, yes. Many Aberdeen clients continue to live in their homes during single-storey extensions. We plan work to minimise disruption, keep the site safe, and clearly communicate when water or electricity access will be affected. For larger extensions, you may want to temporarily move certain areas or rooms.

Look for a builder with:

• Proven experience in extensions

• Positive reviews and testimonials

• Transparent quoting and communication

• Appropriate insurance and certifications

• A portfolio of completed projects

At Sharpsaw, we’ve built a strong reputation in Aberdeen for professional, well-managed home extensions with a focus on client satisfaction.

Lease extensions typically apply to flats or leasehold properties, and solicitor fees can vary from £500 to £1,500+ depending on complexity. Most home extensions on freehold houses in Aberdeen won’t involve lease extension unless your property has title restrictions. We can help you clarify this during the initial consultation.

Conservatories are generally cheaper, but they offer less insulation and year-round usability. A well-insulated home extension adds more value and long-term functionality. If you're after true living space, especially in Aberdeen's climate, a proper extension is usually the better investment.

Start by getting a feasibility assessment of your property. From there:

1. Define your goals and must-haves

2. Set an initial budget

3. Talk to a professional builder or architect

4. Check local planning rules

5. Get detailed drawings and quotes

Sharpsaw offers design support, free consultations, and project guidance from start to finish.

This depends on your budget, goals, and market conditions. With building material prices stabilising in 2025 and growing demand for space at home, now is a great time to invest in a quality home extension in Aberdeen. Waiting may not reduce costs and could delay the benefits of extra space.

To boost energy efficiency:

• Use high-quality insulation

• Choose double or triple-glazed windows

• Install efficient heating and lighting systems

• Consider underfloor heating or solar panels

At Sharpsaw, we advise on materials and systems that meet Scottish energy standards while saving you money long-term.

Open-plan kitchen-diner extensions, loft conversions, and rear or side-return extensions often add the most value. Adding an extra bedroom or a home office is especially popular in Aberdeen’s current housing market. The key is to enhance functionality and flow.

Yes - a quality home extension can add up to 20–25% to your property’s value, depending on the location and type of extension. Beyond financial value, it also enhances your lifestyle by providing more room for family life, work-from-home setups, or relaxation.
