House Extension Types for Renfrew Homes
Every home in Renfrew is unique, from the classic sandstone villas on Inchinnan Road to the modern semis near Robertson Park. Cunningham Builds delivers all types of house extensions, tailored to your property and lifestyle. Whether you need a single storey extension for a bigger kitchen, a double storey extension to add bedrooms, or a wrap around extension to transform your living space, our team has the experience to make it happen.
We regularly complete:
- Single storey extensions – Perfect for open plan kitchen extensions, garden rooms, or larger family spaces. Recently, we completed a rear extension on a home near Renfrew Golf Club, creating a stunning open plan kitchen with bi-fold doors leading to the garden.
- Double storey extensions – Add bedrooms, bathrooms, or a home office. In Dean Park, we built a double storey side extension for a growing family, blending seamlessly with the original stonework.
- Loft conversions – Maximise unused attic space. We’ve converted lofts in Ferry Village and Moorpark, turning dark storage into bright bedrooms and home offices.
- Wrap around extensions – Combine side and rear extensions for maximum space. A recent project in the Braehead area created a light-filled, open plan living and dining area with panoramic garden views.
- Side return extensions – Ideal for traditional Renfrew terraces, especially in the Clune Park area, where narrow plots benefit from clever side infills.
- Rear extensions – Open up your home to the garden. We’ve delivered rear extensions with large sliding doors and rooflights, bringing the outdoors in for homes near the River Clyde.
Our team understands the quirks of Renfrew’s housing stock, from period features to modern layouts. We’ll help you choose the right extension type for your home, budget, and future plans.
Planning and Building Regulations in Renfrew
Planning a house extension in Renfrew means navigating local building regulations and council requirements. Cunningham Builds has over 25 years’ experience working with Renfrewshire Council, ensuring every project meets the latest standards and passes inspection first time.
Many single storey extensions and loft conversions fall under permitted development, but larger or double storey extensions often require full planning permission. We handle all paperwork, drawings, and council submissions, so you don’t have to worry about red tape or delays.
Our process includes:
- Site survey and feasibility assessment
- Detailed architectural drawings and structural calculations
- Submission of planning applications and building warrants
- Full compliance with Scottish building regulations, including energy efficiency and fire safety
We’ve successfully secured permissions for projects near Renfrew Town Hall, in Hillington, and across the wider area. Our local knowledge means we anticipate issues before they arise, keeping your build on track.
Popular Home Extension Trends 2026
Renfrew homeowners are embracing modern extension trends to create brighter, more flexible spaces. In 2026, the most requested features include:
- Open plan kitchen extensions with large islands and seamless flow to dining and living areas
- Bi-fold doors and full-width glazing for maximum light and garden connection
- Home offices and garden rooms – essential for remote work and family life
- Energy-efficient builds with high-performance insulation, underfloor heating, and smart controls
- Blending traditional and modern – keeping original stonework or cornicing, but adding contemporary finishes
We recently completed a wrap around extension in the Blythswood area, featuring a vaulted ceiling, skylights, and a stunning open plan kitchen. Another project near the King George V Dock included a bespoke home office with garden views, perfect for hybrid working.
