How We Help
in 3 Simple Steps

Book A Survey Speak To Our Experts
Online Enquiry

Complete our online form and tell us about your property and what you’d like to achieve. Our friendly team will get back to you to discuss your ideas and arrange the next step.

Free Home Survey

We visit your home to carry out a detailed survey and talk through your plans. We will assess the available space, offer design suggestions and provide practical advice. You’ll receive a clear, no-obligation quote.

Professional Installation

Once you’re happy to proceed, our experienced team will take care of everything — from planning and structural work to electrics and plastering, right through to completion.

EXTENSIONS

Extensions That Enhance Your Home

A well-planned home extension is one of the most rewarding investments you can make in your property. At Build Tech, we design and build extensions that genuinely enhance the way you live – adding space and long-term value without the upheaval of moving house.

Home Extensions
01

We offer a full range of extension types tailored to your property and your plans. Every extension is designed around your specific goals, budget and property. We guide you through planning permission requirements, building regulations and design from day one.

  • Single Storey Extensions — Ideal for expanding your living area, kitchen or dining space at ground level
  • Kitchen Extensions — A seamless way to create the open-plan kitchen you’ve always envisioned
  • Double Storey Extensions — Maximise your investment by adding significant space on both floors in one build
  • Wraparound Extensions — Combine side and rear extensions to transform the entire footprint of your home
Loft Conversions
02

Your loft is one of the most underused spaces in your home – and one of the most valuable to unlock. A loft conversion with Build Tech transforms that empty roof space into a beautiful, functional room without losing any of your garden or outdoor area.

  • Dormer Loft Conversions — The most popular choice, extending vertically from the slope of your roof to create a full-height room with maximum headroom and natural light
  • Hip to Gable Conversions — Perfect for detached and semi-detached homes with a hipped roof, converting the sloped side into a vertical gable to dramatically increase internal space
  • Gable Fronted Dormer Conversions — A combination approach that delivers outstanding space and kerb appeal in a single conversion
