Mansi Building & Renovations is a trusted new build contractor delivering high-quality residential construction across Bucks, Berks and Oxfordshire. From bespoke one-off homes to small developments, we manage each stage with clear communication, robust planning and a focus on build quality. Expect a well-run site, dependable timelines and a finished home built for long-term performance.
At Mansi Building & Renovations, we specialise in building new homes from the ground up, with care and precision at every stage.
Whether you already have planning approval and drawings in place, or you are preparing for your build, we can support you through groundworks, structural construction and full fit-out. Our team coordinates trusted trades, manages quality control throughout and delivers a finished home that is compliant, energy-conscious and built to last.
As specialist new build contractors, Mansi Building & Renovations can support you with:
We build bespoke new homes on individual plots, tailored to your layout, materials and architectural style. From traditional family homes to contemporary designs, we deliver a high-quality build with strong attention to structure, insulation and finish. You get a home that feels considered, practical and future-ready.
If you want one team to manage the full process, our turn-key service takes your project from groundworks through to final decoration. This can include kitchens, bathrooms, flooring, carpentry, decorating and final snagging. The result is a home ready to move into or ready for sale, with less stress and fewer moving parts
We complete the surrounding works that make a new build feel finished and functional, including driveways, patios, pathways, drainage, boundary walls and fencing. We can also coordinate basic landscaping to suit the plot and improve kerb appeal. Everything is delivered with durability and neat detailing in mind.
For small developments, we provide structured project delivery across multiple plots with consistent workmanship and site management. We can coordinate build sequencing, access requirements, parking and external works to support efficient delivery.
A successful new build starts below ground. We carry out site preparation, excavation, foundations, drainage runs and service connections to create a solid base for the structure. This stage is planned carefully to support the rest of the build and reduce avoidable delays later on.
If you prefer to manage the internal fit-out yourself, we can deliver a high-quality shell and core. This includes the main structure, roof and external envelope, with openings formed accurately for glazing and doors. It is a flexible option that gives you control over the later stages.
We understand that extending a home is as much about how it feels as how it functions.
Our approach focuses on clarity, coordination and craftsmanship at every stage. From early planning discussions through to final handover, projects are professionally managed with minimal disruption and absolute attention to detail, allowing clients to move forward with confidence.
A successful extension should enhance the original architecture rather than compete with it.
We work closely with architects, designers and structural engineers to ensure every element, from foundations to finishes, is considered, compliant and built to last.
Where required, we can liaise directly with your professional team to ensure a smooth and well-coordinated build process.
Our extensions are defined by precise structural execution, high-quality materials, finishes and clean, well-managed sites.
The result is a refined addition that feels cohesive, balanced and enduring.
This new build project was a full build from the ground up. Our client came to us with the drawings for their dream home. We began the building process soon after.
This build involved laying the full building foundations, structural steel beams, and everything else you can think of! The final product involved a healthy amount of glazing to ensure the interior was sufficiently lit during the day.
We've been working in the beautiful backdrop of the Home Counties for the last decade.

From the outset, we take time to understand your brief, priorities, and how you intend to live within the space. This allows us to provide clear guidance, transparent costs, and a structured programme, enabling informed decisions before work begins. Throughout the build, projects are carefully managed with a single point of contact and regular, meaningful updates. Every stage is planned, coordinated, and delivered with precision, ensuring a smooth and controlled experience from start to finish.
We meet on site to discuss your requirements, budget, and timescales in detail, ensuring the project is clearly defined before moving forward.
You will receive a fully itemised quotation and a realistic construction schedule, providing clarity and certainty from the beginning.
A dedicated project manager oversees all works, coordinating trusted trades and maintaining an organised, safe, and professional site at all times.
Before completion, every detail is carefully reviewed to ensure the standard of finish meets our expectations. Only when you are happy, we are happy.
A decade of experience creating beautiful spaces in Bucks, Berks and Oxfordshire.
