Reclaim Your Space with Storage Designed for the Unique Architecture of South Wales
Is your home’s potential being cut short by awkward alcoves, slanted ceilings, or the lost space under your stairs?
In the historic terraces of Cardiff, the coastal cottages of The Mumbles, and the modern developments of Newport, standard flat-pack furniture rarely fits. It leaves unsightly gaps, wastes valuable square footage, and fails to respect the character of your property.
At TJS Construct Ltd we do not just build cupboards. We engineer Structural Garden Annex and Bespoke Built-In Storage solutions that blend seamlessly into your home footprint.

Why South Wales Homeowners Trust Our Bespoke Joinery
In 2026, home organization is more than aesthetics about well-being and property value.
Our process is designed to solve the specific spatial pain points found in Welsh homes.
Custom built-in solutions outperform freestanding furniture by fitting your room’s exact contours.
Whether it’s a floor-to-ceiling library or a clever under-stairs pull-out, bespoke carpentry perfectly blends high-end aesthetics with maximum utility.
- Victorian & Edwardian Alcove Units
Most South Wales terraces feature chimneys that create deep, uneven alcoves.
We design hand-scribed cabinetry that integrates with the Non-Standard Structural Masonry typical of South Wales period properties.
- Precision-Fitted Loft & Eaves Wardrobes
Whether it’s a loft conversion in Penarth or a cottage in the Vale of Glamorgan, slanted ceilings are a storage nightmare.
Our custom-angled wardrobes utilize 100% of the vertical height, giving you double the storage of a standard standing unit.
- Precision-Fitted Loft & Eaves Wardrobes
The space under your stairs is often the most underutilized area in a home. We transform these voids into:
- Pull-out shoe drawers for busy family hallways.
- Integrated home offices (cloffice) for the hybrid worker.
- Sleek utility housing for appliances and cleaning tech.
