Every project is handled with care, professionalism, and technical expertise. Whether you need a complete property overhaul or small-scale updates, we have the tools and the team to deliver.
New Build Homes
From initial consultation to final handover, JJ Construct manages every stage of the new build process. We work closely with clients, architects, and engineers to ensure all specifications are met, deadlines respected, and materials chosen to last. Each home we build is modern, energy-efficient, and crafted with durability in mind.
Our new builds reflect contemporary standards and personal taste—perfect for individuals or families starting from scratch and seeking a space that fits their lifestyle from day one.
Apartment Refurbishments
Urban living often demands smart upgrades. That’s why our apartment refurbishment services are tailored to modern expectations. We transform outdated spaces into functional, stylish interiors that improve comfort and add property value. Whether you’re preparing to rent, sell, or simply enhance your living experience, JJ Construct delivers.
We handle layout changes, kitchen and bathroom upgrades, surface finishes, joinery, and decorative detailing—always with efficiency and minimal disruption.
Home Extensions
Home extensions are one of the most effective ways to improve liveability without relocating. JJ Construct designs and builds seamless single- and multi-storey extensions that increase space while maintaining architectural continuity.
Whether it’s a kitchen expansion, a new lounge, or an entire extra floor, we manage planning permissions, construction, utilities, and finishes. We prioritise structural integrity, natural light, and flow between the old and the new.
Loft Conversions
Lofts are full of untapped potential. JJ Construct converts these underused spaces into light-filled bedrooms, offices, or entertainment rooms with custom layouts and high-performance insulation. Our loft conversions not only enhance functionality but also significantly increase property value.
Each project is approached with precision—meeting building regulations, delivering bespoke solutions, and improving your home’s energy efficiency.

Regular maintenance is key to keeping properties in top condition. Our expert tradespeople provide reliable services that cover plumbing, electrics, plastering, carpentry, tiling, and more.
