Single Storey House Extensions Cardross: Seamless Indoor-Outdoor Flow

Single storey house extensions in Cardross are the fastest way to unlock new space and transform the way you live. Cunningham Builds has delivered dozens of these projects across the village, from the leafy lanes off Barrs Road to the family homes near Geilston Gardens. Our team knows how to design and build extensions that blend perfectly with Cardross’s sandstone villas and modern semis alike.
We specialise in creating open-plan kitchen-diners, sun-drenched family rooms, and rear extensions that connect your home to the garden. Bi-fold doors, roof lanterns, and large windows are standard features, maximising natural light and making the most of those River Clyde views. Our single storey extensions typically complete in 8-12 weeks, with minimal disruption and a finish that looks like it’s always been part of your home.
Recent project: On Station Road, we extended a 1930s semi with a wraparound kitchen-diner, adding over 30m2 of living space and a seamless flow to the patio. The owners now host family gatherings with ease, and the extension’s natural light has transformed their daily life.

Double Storey Extensions: Maximise Value in Growing Families

Double storey extensions are the ultimate way to future-proof your Cardross home. Whether you’re in a classic villa on Main Road or a newer build near the golf course, Cunningham Builds delivers double storey extensions that add bedrooms, bathrooms, and serious value. We understand the unique character of Cardross’s architecture and always ensure your extension enhances both the look and the function of your property.
Our double storey projects typically run 12-16 weeks, with careful planning to keep your family comfortable throughout.

Many clients choose to add a master suite upstairs and a spacious kitchen or playroom below, creating flexible space for growing families.
Example: In the heart of Cardross, we recently completed a double storey rear extension for a family on Darleith Road. The result? Two new bedrooms, a luxury en-suite, and a light-filled kitchen that’s now the hub of the home. The family avoided the stress of moving and gained the space they desperately needed.

Loft Conversions Cardross: Urban Space Without Footprint Changes

Loft conversions are a smart way to add space without extending your home’s footprint, ideal for Cardross’s characterful properties where garden space is precious. Cunningham Builds has converted lofts in everything from traditional bungalows near the train station to modern homes overlooking the Clyde. We know how to work with tricky rooflines and local building regulations to deliver stunning results.
Our loft conversions typically take 6-10 weeks, transforming unused attics into bright bedrooms, home offices, or even self-contained studios. We’re experts in adding rooflights, dormers, and clever storage to maximise every inch. One recent project on A814 saw us turn a dark loft into a spacious guest suite with panoramic river views, adding both value and wow factor.
