Bespoke Extension Solutions for Every Swansea Home
Looking for extra room without moving? Our home extension service in Swansea delivers light-filled kitchens, spacious family rooms and versatile loft conversions—all tailored to your property type and lifestyle. We begin with an in-depth consultation on site, then craft a concept that respects neighbourhood character while maximising internal space.
From Victorian terraces in Uplands to coastal bungalows in Mumbles, no two projects are alike. That’s why every layout, roof form and façade detail is customised—to blend seamlessly with your existing architecture and add genuine kerb appeal.
By combining creative flair with practical know-how, iForma unlocks the hidden potential of your plot—adding space, value and everyday enjoyment.
Whether you’re extending a semi-detached in Sketty or adding a sunroom in Gower, we adapt our designs to your street, views, and building restrictions. Our team ensures that each extension is not just functional, but enhances the feel and flow of your living space. The result? A space that works for your lifestyle today and adapts with your family tomorrow.
See It First: 3D Visualisation & Space Planning For Swansea Home Extensions
Before any foundations are poured, you’ll step inside a photorealistic 3D model of your proposed extension. Explore furniture layouts, glazing options and natural-light patterns; swap materials with a click; and sign off only when the design feels perfect.
This digital preview eliminates guesswork, speeds up decision-making and provides a powerful visual aid for neighbours or planning officers—boosting approval rates for Swansea extension applications.
These immersive previews are a game-changer for clients unsure how their ideas will translate into real space. We take your feedback on board and revise layouts in real time, saving both time and money during the build phase. It’s one of the many ways iForma ensures your extension is a perfect match before a single wall is built.
Home Extension Planning Permission & Building Regulations—Sorted
Extension rules differ between Morriston and the Gower AONB, so local insight matters. iForma prepares drawings, heritage statements and structural calculations, submits them to Swansea Council and liaises with building-control inspectors—keeping your project compliant and on schedule.
We also advise when your scheme qualifies for permitted-development rights, helping you avoid unnecessary paperwork and fees.
We stay on top of local policies and conservation constraints, ensuring that your home extension plans are both approved quickly and built legally. Our relationship with Swansea planning officers allows us to anticipate common challenges and solve them early, making the process smoother for everyone involved.
Single-Storey Rear Extensions
Open up cramped ground floors with seamless kitchen-diner additions that connect your home to the garden. Ideal for creating light-filled family spaces, they’re a cost-effective way to improve flow and function.
Double-Storey Side/Rear Builds
Add bedrooms above and social zones below—doubling usable floor area while preserving curb appeal. These extensions maximise living space without compromising garden or plot footprint.
Wrap-Around Extensions
Combine side-return and rear spaces to form a spacious L-shaped layout that transforms internal movement. They’re perfect for creating open-plan zones with panoramic garden views.
Loft & Dormer Conversions
Turn underused attic space into stylish bedrooms, home offices, or ensuites with added headroom and light. We manage structure, insulation, and finishes for full compliance and comfort.
Permitted-Development
We assess your home’s eligibility for building without planning permission under PD rights. This helps streamline the process and reduce costs while still maximising usable space.
Turnkey Project Management
From initial design to final decoration, we handle every stage of your Swansea extension under one roof. With one contract and one point of contact, your build stays smooth, efficient, and on budget.
Seamless Extension Build & Project Management
Once permission is granted, our site team moves in with a clear programme of works. We schedule trusted local trades—bricklayers, roofers, electricians—under one project manager, ensuring quality craftsmanship and tidy, respectful sites.
Weekly progress reports, cost trackers and milestone photos keep you fully informed, whether you’re living on site or checking in from the office.
From steel installations to roofing and first fix, we coordinate each phase to avoid delays and maintain site safety. We manage tradespeople, order materials, and supervise quality—so you don’t have to. Whether you want weekly meetings or light-touch involvement, we tailor our service to suit your preferred level of oversight.
Energy-Efficient, Future-Proof Extensions
A bigger home in Swansea shouldn’t mean bigger bills. We specify high-performance insulation, thermally-broken glazing, and optional solar or air-source technologies to keep extensions warm in winter and cool in summer. Sustainable materials and airtight construction further reduce running costs—good for your wallet and the planet.
We also futureproof your space by factoring in smart wiring and infrastructure for solar panels, EV chargers, and zoned heating. Our builds don’t just meet current standards—they anticipate future needs, creating homes that are easier to maintain, cheaper to run, and better for the environment.
Domestic vs Commercial Extensions
Domestic House Extensions Swansea
Families grow, hobbies change and hybrid working demands new zones. From side-return kitchens to loft dormers with ensuites, our domestic extensions create flexible, light-rich living spaces tailored to Swansea lifestyles.
Commercial & Home-Office Extensions Swansea
Need a larger studio, salon or garden office? iForma designs small-scale commercial and live-work extensions that satisfy business regulations, acoustic requirements and branding—perfect for entrepreneurs expanding within their own plot.
