Trusted Builders in Alwoodley for Loft, Garage & Basement Conversions
We design, manage and build conversions in Alwoodley — safely, legally and to a high finish — so you get real, usable space that adds value.

Design & Build Packages
Our all-in-one design and build packages simplify the conversion process. From the initial consultation and architectural drawings to planning permissions, construction, and finishes, we provide a complete service under one roof. This approach saves you time, reduces stress, and ensures consistent quality at every stage. Whether it’s a loft, garage, or basement conversion, our design and build team delivers a project tailored to your needs, style, and budget. With clear timelines, regular updates, and a single point of contact, your project runs smoothly from start to finish.

Dormer Conversions
Add space and natural light to your loft with a dormer conversion. Ideal for properties with limited headroom, dormers create comfortable, liveable rooms with proper ceiling height. We manage design, structural work, planning permissions, and building regs, ensuring your dormer blends seamlessly with your existing roofline. Options include flat-roof, gable, or full-width dormers, tailored to your home and budget. With careful planning and skilled craftsmanship, your new dormer conversion provides usable space for bedrooms, bathrooms, or offices — all finished to a high standard.

Hip-to-Gable Conversions
Perfect for semi-detached and detached homes, a hip-to-gable conversion extends the sloping side of your roof into a vertical wall, unlocking valuable loft space. This type of conversion allows for larger, brighter rooms with increased functionality. Our team handles everything from structural alterations and design approval to insulation, electrics, and finishes. Whether you’re adding a master suite, a home office, or a playroom, hip-to-gable conversions provide a practical and cost-effective way to expand your home without the need for a full extension.

Garage Conversions
Turn your underused garage into a warm, functional living space. Whether it’s a bedroom, gym, home office, or utility room, we transform garages into fully integrated parts of your home. Our service covers insulation, damp-proofing, electrics, plumbing, and internal finishes, ensuring your new space is comfortable year-round. We manage structural work, windows, and access points so your conversion blends seamlessly with the rest of your property. A garage conversion is one of the fastest, most cost-effective ways to add usable space and value to your home.

Loft Conversions
Maximise unused roof space with a bespoke loft conversion. Whether you need an extra bedroom, a home office, or a studio, we design and build bright, well-insulated lofts that feel like a natural extension of your home. From structural calculations and dormer windows to fire safety and staircase design, we handle everything. Our process ensures full compliance with building regulations while minimising disruption. The result is a stylish, functional space that adds significant value and practicality to your property, completed on time and within budget.

Mansard Conversions
For maximum space, consider a mansard conversion. Built by altering the roof’s structure to create a steep slope, mansards often run across the full width of the house. This type of conversion delivers a large, flexible living area that feels like a new floor of your home. Though it requires planning permission, our team manages every step, including design, approvals, structural work, and finishes. Mansard conversions are perfect for creating multiple rooms or a luxurious master suite, combining practicality with a stylish, modern finish.

Two-Storey Conversions
Expand your home vertically with a two-storey conversion. By combining a loft conversion with a reconfigured first floor, you can create multiple new rooms without extending into your garden. This option is ideal for growing families who need extra bedrooms, bathrooms, or office space. Our team takes care of planning, design, and structural engineering, delivering a seamless build that integrates perfectly with your existing property. With expert project management, you’ll gain the space you need quickly and efficiently, without compromising on quality or compliance.

Basement Conversions
Unlock hidden potential with a basement conversion. We specialise in turning dark, unused spaces into bright, functional rooms — from home cinemas and gyms to guest suites and playrooms. Our team handles tanking, waterproofing, ventilation, and lighting design, ensuring a dry, comfortable environment. Structural works, electrics, and finishes are all included, giving you a high-quality space that feels like part of your home. Basement conversions not only add valuable living space but can also significantly increase property value, particularly in urban areas where space is at a premium.

John Paul and his band of Merry workers did a great job that we were really pleased with - efficient, on time, great finish and showed really good flexibility - we don't leave positive reviews often - but these guys deserved it. I highly recommend it - excellent professionals, work done on time (!), precise and clean! John Paul met a difficult challenge in the very short time I needed, all materials were purchased, good finishing with the right dose of humor - I highly recommend it!
