Barn Conversions
Barn Conversions in Hertfordshire, Bedfordshire & Cambridgeshire
A well-planned barn conversion can turn an unused or ageing agricultural building into a beautiful, practical home or additional living space.
LJT Construction has been delivering high-quality conversions across Hitchin, Bedford, Cambridge and the surrounding areas for almost 20 years, combining traditional character with modern comfort, insulation and building standards.
Barn Conversion Specialists
A barn conversion is a chance to create something genuinely individual: a light-filled family home, a stylish annexe, a workspace or extra accommodation that retains the original character of the building.
From initial feasibility and structural surveys through to insulation, windows, kitchens and finishes, LJT Construction manages the whole project.
You benefit from one experienced team coordinating every stage, rather than having to manage separate trades yourself.

Do You Need Planning Permission?
Most barn conversions require planning permission, particularly where an agricultural building is being changed into a home or separate living accommodation. In some cases, permitted development rights may apply, but this depends on the building’s location, history, use and any restrictions affecting the site. For the official rules, see the Planning Portal guidance on change of use.
Building Regulations approval will also be needed to ensure the conversion meets current standards for structure, insulation, fire safety, drainage, ventilation and energy efficiency. We will assess the likely requirements during the initial survey and guide you through the process.
FREQUENTLY ASKED QUESTIONS
How long does a barn conversion take?
Every project is different, but a typical barn conversion can take several months, depending on the size and condition of the building, the amount of structural work required and the specification of the finish. We will provide a clear programme before work begins.
Can you manage the whole barn conversion project?
Yes. As experienced barn conversion builders, LJT Construction can manage the project from the initial survey and structural work through to plumbing, electrics, kitchens, bathrooms, flooring and final finishes.
Can original features be retained?
Where structurally practical, we always aim to retain and showcase the features that give a barn its character, such as exposed beams, original brickwork, timber framing and high ceilings.
How much does a barn conversion cost?
Costs vary considerably according to the building’s condition, required structural work, access, services and the level of finish you choose. We provide a detailed, transparent quotation after assessing the property and discussing your plans.
