Single-Storey Side Extension with Roof Lantern & Garage Gym Conversion
This project involved the construction of a single-storey side extension, complete with a roof lantern to bring more natural light into the home. Part of the existing garage was converted into a practical home gym, while the garage roof height was altered and a new rooflight was installed to improve space, comfort and usability.
External Render Removal & Reinforced Re-Rendering
This project involved stripping the existing render and preparing the exterior surface for a stronger, longer-lasting finish. We combined aluminium mesh with a plaster cement render system to reinforce the surface, improve durability and create a cleaner, more reliable exterior finish.
Two-Storey Rear Extension & Detached Outbuilding
This project included the construction of a two-storey rear extension, creating additional living space across both floors of the home. A detached outbuilding was also built to provide extra usable space, offering a practical solution for storage, work, leisure or future flexible use.
Structural Alterations & Box Frame Installation for Open-Plan Living
This project involved structural alterations and the installation of a box frame to safely support the property after internal walls were removed. By incorporating a structural beam and two columns into the design, the kitchen was transformed into a fully open-plan space — turning a structural requirement into a strong architectural feature.
Annex Accommodation Build
This project involved creating a self-contained annex accommodation, designed to provide a practical and comfortable living space separate from the main home. The build focused on functionality, privacy and long-term usability, making the property more flexible for family living, guests or independent accommodation.
Full Bathroom Renovation
This project involved a complete bathroom renovation, transforming the space into a modern, practical and comfortable room. From preparation and installation to finishing details, the work focused on improving layout, functionality and everyday usability while delivering a clean, high-quality finish.
Open-Plan Kitchen & Living Room Renovation
This project transformed the kitchen and living room into a spacious open-plan area, creating a brighter and more social hub for everyday living. A structural beam was installed to support the new layout, while zoning helped keep the space practical and well-defined. The renovation also included a new kitchen, new tiled flooring and laminate-effect finishes for a clean, modern look.
Ground Floor Tiling with RAK 1.2m x 1.2m Tiles
This project involved removing the existing kitchen floor and preparing the surface for a durable, high-quality tile installation. We installed Ditra Mat across the ground floor to improve stability and protection, followed by large-format RAK 1.2m x 1.2m tiles for a clean, modern and premium finish.
