Extensions & Architectural Additions

At Spiller Construction Ltd, we build refined architectural extensions and bespoke additions for residential properties across Oxfordshire, Berkshire and Buckinghamshire and the surrounding areas.

Our clients trust us to enhance their homes (old and new) with beautifully considered spaces that increase light, flow, and functionality.

At Spiller Construction, we believe an extension should feel like a natural evolution of the home rather than an afterthought.

Seamless Architectural Extensions

We specialise in creating extensions that enhance space, light, and connectivity without compromising the property’s original character.

Through careful construction, we ensure that each addition feels fully integrated both internally and externally.

Structures & Lifestyle Spaces

We construct bespoke additions that elevate both lifestyle and property value.

Material Matching & Fine Detailing

Materials and detailing are meticulously selected and matched to ensure complete harmony with the existing building.

From brickwork and stone to joinery and finishes, every element is carefully considered to maintain architectural continuity.

Enhancing Homes with Purpose & Precision

Extensions & Bespoke Additions

We work closely with architects and designers to create cohesive, elegant expansions that balance form and function. Our collaborative approach ensures each extension is technically sound, visually refined, and aligned with planning and structural requirements.

At Spiller Construction, we focus on creating extensions that are intelligent, beautiful, and built to endure. We focus on enhancing both the experience of living in your home and its long-term value.
