House Extensions & Alterations

Practical designs for single-storey, two-storey and property alterations.

House Extension Design in Merthyr Tydfil and South Wales

A well-designed extension can provide the additional space your family needs while improving how your home looks, feels and functions.

Utopia Design creates practical, considered designs for house extensions and property alterations throughout Merthyr Tydfil and South Wales.

Create More Space in Your Home

Every home and household is different. You may want a larger kitchen, an open-plan living area, an additional bedroom, a home office or a better connection to the garden.

We begin by understanding how you currently use the property, what is not working and what you would like the finished space to achieve. We then develop a design that responds to your home, available space and budget.

Good to Know

Design, Planning and Building Regulations

We can support your extension from the initial site survey and concept design through to planning application and Building Regulations drawings.

The service can include existing and proposed plans, elevations, sections, technical details and the information required for the relevant application stage.

Designed to Complement Your Property

A successful extension should feel like a natural part of the home. This does not always mean copying the existing building exactly. A carefully designed contemporary addition can work alongside a traditional property when its scale, materials and proportions are properly considered.

Our approach balances appearance, practicality, natural light, circulation, storage and buildability.
