Planning a house extension: 5 key things to know

Planning a house extension

A house extension can completely transform your home - adding space, light and value, but without careful planning, it can become stressful and expensive. At SOLV we are experts in guiding homeowners through the process to create extensions that are practical, beautiful and future-proof. Here are five key things to know before starting your project.

1. Understand Planning Permission Requirements

Before you start designing, check if your extension needs planning permission. There are specific rules, especially for period properties or houses in conservation areas. A qualified architect can guide you, helping you avoid costly mistakes or delays.

2. Consider the flow and Function of Your Home

Think about how your extension will connect with your existing house:

  • Will it improve daily living or just add more floor area?

  • How will light, ventilation and circulation work?

  • Is it future proof - accessible for an ageing or a growing family?

    SOLV architects can help you understand how your new space will feel.

3. Choose Materials Wisely

Houses come in a mix of traditional and modern styles. The materials used should respect and harmonise with the local character:

Flint and brick for a traditional look

Charred timber and glass for a contemporary twist

Sustainable materials

4. Plan Your Budget Early

Extensions can vary widely in cost depending on size, complexity and  materials. Early-stage budget planning helps avoid surprises.

Architects can provide realistic cost estimates and suggest design alternatives to keep your project on track.

SOLV architects produce a detailed working drawing package to help builders price accurately so there are less surprises along the way.

5. Work with the right Architect

The right architect turns your vision into a functional, beautiful and buildable design. We guide clients through every step: from initial sketches and planning applications to contractor selection and build. We have years of experience and are chartered with RIBA and ARB.

Planning an extension doesn’t have to be overwhelming. With the right guidance and considered design, your new space can enhance your home for years to come.
