Services
House Extensions
House extensions provide cost-effective solutions to expand living space without relocating. We design and build custom extensions that enhance property value and functionality. Our process ensures minimal disruption while delivering high-quality results tailored to your lifestyle needs.
Loft Conversions
Loft conversions maximise unused vertical space to create bedrooms, offices, or playrooms. We handle structural requirements and insulation to ensure comfortable, compliant living areas. Our expertise guarantees efficient use of space while maintaining architectural integrity.
Garage Conversions
Garage conversions repurpose existing structures into functional rooms like gyms, studios, or guest spaces. We manage electrical, plumbing, and insulation upgrades to meet building regulations. Our approach balances practicality with aesthetic appeal for versatile living areas.
Orangeries
Orangeries combine traditional elegance with modern functionality using glass and brick elements. We design light-filled spaces ideal for dining or lounging, incorporating energy-efficient materials. Our orangeries enhance natural light while providing year-round usability.
Garden Rooms
Garden rooms create versatile extensions for entertainment or relaxation. We construct insulated, weatherproof structures that blend with outdoor environments. These spaces offer flexible layouts suitable for home offices, hobby rooms, or social areas.

Thank you so much to the team at Phoenix for creating a beautiful rear single storey extension for us. This wet room has been life changing for Gareth. The whole process was made actually enjoyable by you all.… No stress, no hassle and nothing was ever too much. The build quality is second to none, everything has been finished to the highest standard and deadlines were met ahead of schedule too. Extremely clean, fast workers who really take pride in their work. Always on time, always smiling & a pleasure to have working here. Thank you so much again!
