NEW BLOG: Permitted Development Rights — what can you actually build without planning permission?

There are plenty of myths and half-truths around Permitted Development — from how far you can extend, to loft conversions, garage conversions and garden buildings.

Our latest blog breaks down the rules in plain English, explains where restrictions can apply, and highlights why planning permission isn’t the only thing you need to think about — Building Regulations matter too.

If you’re thinking about extending or altering your home, it’s a useful place to start before you make any plans. Have a read now: https://www.se-addition.co.uk/post/permitted-development-rights-what-can-you-build-without-planning-permission

1,000 trees planted. 🌱

As a collective working across architecture, engineering, surveying and the built environment, we know that the decisions we make today can have a lasting impact on the places and communities around us.

That responsibility doesn’t stop at the projects we work on.

Through sponsorship across the Collective, we’ve now reached 1,000 trees planted with JUST ONE Tree — supporting reforestation, biodiversity and communities further afield.

It’s a small part of what we can do, but an important reminder that collective action adds up.

Here’s to the next 1,000...

Remember this 150-year-old cottage Addition?

We shared the before-and-after recently, now hear directly from our clients about the project, how we worked together to understand the way their family lives, and what the finished home means to them.

From connecting the original cottage with its former garage to creating a new social hub for family and friends, every part of the design was carefully considered.

And there’s more to explore — head to our website for the full case study, including the full video showcase and before and after photography: https://www.se-addition.co.uk/new-heart-150yr-cottage

A dated detached property, reworked around the needs of the people who live there.

The project involved a complete overhaul of the layout, a two-storey extension, loft conversion and new external cladding — a substantial transformation, but one that started with getting the brief right.

Taking the time to understand how our clients wanted to use the space, and what mattered to them day to day, helped shape the design from the outset.

As the clients put it: “The design was spot on from the start.”...and that's always great to hear!

Modern Heart for a 150 year old home - Before : After

This 150-year-old cottage had a cosy layout and traditional proportions, but they didn’t quite lend themselves to the social hub this much-loved family home needed.

The new addition connects the original cottage and former garage to create a generous kitchen and dining space, additional shower room, as well as a welcoming new entrance and light-filled setting for family life and entertaining.

By understanding how the family live and what they wanted from the build, we were able to carefully rethink how the spaces connect and flow. The result is a home that feels spacious, welcoming and perfectly suited to the way the family lives today.

Swipe to see the transformation!

And there’s more to come... We’ll be sharing the full case study soon, with video and full gallery to showcase this bright new space and hear how it's impacted family life.

Planning approval secured!

Planning isn't always a straight line, but the best outcomes often come from listening, collaborating and responding to feedback.

For this project, we secured planning approval for significant extensions and alterations after refining the proposals and providing a robust Planning Statement and Heritage Statement to demonstrate how the design would respect the neighbouring listed building while delivering the additional space our clients needed.

With Ground floor rear/side extensions and first floor rear extension, as well as creating a new front access, It's set to be quite a transformation and is a great example of how a collaborative, considered approach can overcome planning challenges and achieve a successful outcome

Every project is different, but taking the time to understand the planning context, address concerns and present a well-justified case can make all the difference.

Every home has its own story, and every project starts with understanding how our clients want to live.

For this rural property, we secured planning permission for a substantial two-storey addition—effectively doubling the footprint of the original cottage—alongside a contemporary kitchen extension that better connects the existing home to its generous setting.

Projects like this are about more than adding space — they’re about understanding how a home needs to evolve, and helping make that transition a positive one.

Could your home work better without building bigger?

You've decided you need more space… so an extension is the answer. Or is it?

It's often the first solution homeowners think of, but before designing an extension, it's worth asking another question...

Could your existing home work harder?

An early site visit allows us to look beyond the floor plan. We consider how your home is used, how natural light moves through the spaces, how it connects to the garden, and the opportunities and constraints of the site. This helps us explore solutions that go beyond simply adding more floor area.

Before developing a design, we take the time to understand what you want your home to deliver—creating spaces that are tailored to the way you live, both now and in the future.

Sometimes the answer is an extension. Sometimes it's a clever reconfiguration of the existing layout. Often, it's a combination of both.

Before we think about adding to a property, we take the time to understand it...
Let's start the conversation with a free consultation.

How do you extend a home that's already been transformed?

When a project evolves, it's important that every new addition feels like it was always meant to be there.

Following the renovation and conversion of this beautiful barn by our sister company, Swann Edwards Architecture Ltd , the clients returned with plans to expand the property with a pool house, garages, a gym and guest accommodation.

Working collaboratively, Swann Edwards Architecture and SE Addition developed a design that complements the character of the renovated barn while continuing contemporary spaces tailored to modern living, with a natural flow between the old and new spaces.

A carefully selected palette of materials helps to connect old and new, continuing the story of the original conversion. Exposed natural textures sit alongside refined, high-quality finishes, creating spaces that feel both timeless and contemporary.

The result is an extension that enhances the existing home without competing with it—adding space, function and character in equal measure.

Swipe through to see how the extension feels like a natural continuation of the original barn, or head over to the video hub to watch the full showcase: www.be-collective.co.uk/video-hub
