Modular Extensions North East | Design Build Space

Seamless Extensions, Built Around Your Lifestyle

Imagine more room for family life, entertaining, or simply enjoying your home — without the noise, dust, and disruption of a traditional build.

At DB Space Modular, our extensions are designed for comfort, style, and performance, giving you the extra space you need in weeks, not months.

Why Choose a Modular Extension?

Faster to build – installed in weeks, not months.
Year-round comfort – thermally efficient, warm in winter and cool in summer.
Built to last – precision-engineered steel frame with a 50-year warranty.
Minimal disruption – clean, quiet installation with far less mess than brick and block.
Tailored to you – a choice of exterior finishes and layouts to suit your home.

Designed Around Your Life

Your extension should feel like a natural part of your home. That’s why we offer flexible design options, premium finishes, and seamless integration with your existing property. From bright, open-plan kitchens to cosy family rooms, our spaces are created with modern living in mind.

A Smarter Way to Build

Traditional extensions can mean months of noise, mess, and uncertainty. With DB Space Modular, much of the work happens off-site. That means less disruption, fixed costs, and a stress-free process from start to finish.

Our current build price is £2500 + VAT per SQM within a 30-mile radius of Teesside. This includes foundations, external finish of slips, render or composite, basic electrics and plastering. If you opt for an upgrade of PVC to Aluminium windows and doors and decide to have lanterns or skylights fitted, then these costs need to be added to your overall quote.

Process

It all begins with a site survey and discussion to see what your plans are.

We brief the architect and arrange a site visit and survey. At this time the architect will be able to advise on wether the project needs planning permission.

Plans and drawings can be made. Once they have been signed off by you we can then provide you with a photo realistic render of how your extension will look.

A planning application is processed if necessary.

Upon a successful application we can then arrange a project start date.

Frequently Asked Questions

How long does a modular extension take to install?

Most projects are completed in just a few weeks, with on-site installation often taking only days — far quicker than a traditional build.

Do modular extensions meet building regulations?

Yes. Our extensions are designed and built to meet all relevant UK Building Regulations, giving you the same performance and security as a traditional extension.

Will my extension match my home?

Absolutely. We offer a range of external finishes — from modern cladding to brick slips — so your new space blends seamlessly with your property.

Are modular extensions warm in winter?

Yes. Our steel-frame systems are highly insulated and airtight, ensuring your space stays comfortable and energy-efficient all year round.

Do I need planning permission?

In many cases, modular extensions can be built under permitted development rights. We’ll advise you during your survey and handle any planning applications if needed.

What foundations do you use?

We specialise in ground screw foundations — fast to install, less disruptive, and suitable for a wide range of ground conditions.
