Avoid cowboy work - you’ll get a reliable house extension backed by two and a half decades of combined building experience.
Get total respect for your property - we’ll leave the site neat and tidy at the end of each day.
Always know what’s going on - you will have a designated project manager who will always keep you up to date to ensure work gets completed as you wish.
Be protected by a conditional 1-year warranty and a 10-year structural guarantee.
Avoid hidden fees or last-minute cost overruns - you’ll get a detailed rundown of all costs involved before you sign the contract.
Pay in arrears and avoid the risk of being ghosted - you’ll pay a small 10% deposit at the start and the rest gradually as work gets completed.
Have your project completed on time and on schedule.
Have your life made easy - all you’ll have to do is show us your idea - then we’ll take care of the rest, from legal permissions to planning, designing, and building.
Step 1: Free Quote and Home Consultation
We’ll visit your property to assess the space and provide a detailed quote. You’ll receive a clear proposal with a project timeline & costs — covering everything from construction and plumbing to electrics, glazing, doors, and VAT.
Step 2: Design Phase
The design stage is centred on your vision. We’ll listen to your ideas, refine the layout, and provide 3D models so you can clearly visualise everything before the build begins.
Step 3: Pre-Construction Preparation
Before work begins, we’ll finalise designs, secure all approvals, order materials (full supply and fit), and schedule our team.
Step 4: Build Phase
You’ll meet your dedicated Total B Construction team, including your project manager, interior designer, and more. They’ll lead the entire process from start to finish, working with you every step of the way to bring your dream home to life.
Step 5: Handover & Guarantee
Once the project is complete, we’ll pack and tidy everything up. Your project will include a 10-year structural guarantee and a 1-year workmanship guarantee for your complete peace of mind.
Our team is here to answer your questions and help you get started with your construction project.

Absolutely. We have £10m Public Liability insurance, so you, your family, and your property will be fully covered in the unlikely event of an accident or damage.
Yes! Every single member of our team at Total B Construction is fully licensed and qualified.
Yes! If you don’t already have planning permission or other necessary legal approvals, we’ll handle the entire process for you — at no extra cost. If you’ve already secured the permissions yourself, that’s perfectly fine too; we can work with what you have and move forward smoothly.
Yes, we provide a full supply and fit service, meaning we’ll source all the materials needed for your project and handle the installation for you, and the cost of that will all be included in our quote — so you don’t have to worry about a thing.
Our 10-year structural guarantee is our promise that the core structural elements of your project — such as the foundations, load-bearing walls, steelwork, and roof structure — are protected against defects in materials or workmanship for a full decade after completion.
It applies to all major construction projects we carry out, including new builds, extensions, loft conversions with structural changes, and substantial renovations that involve structural work.
It does not apply to purely cosmetic or non-structural renovations — such as painting, decorating, kitchen/bathroom refits, flooring, or similar updates.
We offer a 12-month defects liability period, which means that for one year after your project is completed, we’ll fix any defects or issues caused by our workmanship or materials — free of charge. This covers things like minor cracks from settlement, faulty fittings, or any other snagging issues that arise within that period.
Project timelines vary depending on the scope of work. However, we can provide you with an accurate timeline if you contact us and tell us more about your project.
Yes, we offer free, no-obligation estimates for all construction services. Simply contact us today to schedule a consultation.
If we’re working on your project—whether it’s an extension, remodel, conversion, or new build—and you need help with the interior design, then our interior designers will help you out and create drawings to bring your vision to life – free of charge. If you already have your mind set on a clear design, or if you have drawings ready, that’s absolutely fine too, and we’ll work with what you have.
We source our materials from trusted suppliers like Travis Perkins, Builder Depot, and Selco, ensuring everything we use meets our quality standards for durability and finish.
Nope – we’ve got our own architects and engineers on the team.
Total B construction has been around since 2018, but our crew and director have been building for a combined time of over two decades and a half.
Yes, many of our clients choose to stay living in their home during the build, and it’s definitely possible to do so. If you’d like, we can even install a temporary kitchen to use until your new kitchen extension is complete.
One important thing to keep in mind: if your property doesn’t have rear access, all materials and equipment will need to be brought through the house.
In these cases, we take great care to fully protect your hallways and floors throughout the project.
If you want to talk about your project, your main point of contact will be your dedicated Project Manager, or our company director, Adrian.
They oversee every build from start to finish, keeping you updated at every stage and helping with any outstanding decisions—like electrical layouts or finishes—so everything runs smoothly.
They’re here to make the process easy and stress-free for you.
Every build we take on is overseen by a dedicated Project Manager, your go-to contact for the entire construction phase.
They’ll keep you updated at every stage and help you tie up any remaining details—like electrical layouts—before work moves forward.
Their role is to keep everything running seamlessly, so you can enjoy the process without the stress.
