Why comfort all year round matters here

Sunderland winters can be cold, damp and windy, especially close to the coast at Roker and Seaburn. A garden room that is only pleasant on a warm afternoon soon turns into somewhere to keep the garden chairs. The whole point of a garden room is that you use it, every week of the year.

That is why our garden rooms are built with modern insulation, so they are comfortable all year round. It is what makes a garden room work as a home office in January, a salon where clients sit still for an hour, a grooming room, a gym on a dark morning, or a studio you actually want to spend time in.

Where the insulation goes in our builds

You can see it in our build photos. Each room is built on site, stage by stage:

  • the timber floor frame goes in first, with insulation laid between the joists before the floor deck goes down
  • timber stud walls are framed up on the floor deck
  • the roof structure is boarded over with OSB
  • the outside is clad in timber for a professional appearance

The result is a bespoke design with high-quality finishes and modern insulation. Read more on our bespoke garden rooms page.

What else makes a garden room comfortable

Insulation is the starting point, but a few design choices make a real difference to how a room feels day to day. They are worth thinking about before you ask for a quote.

Where the room sits

A spot sheltered from the prevailing wind feels very different from an exposed corner. Think about where the sun is at the times you will use the room, and whether trees or fences shade it.

Windows and doors

Glazing brings in daylight and views of the garden, but where it faces matters. A room used mainly in the morning might want light from a different side than one used in the evening.

Keeping it warm, and fresh

Power and heating needs are discussed at the quote stage, so they are planned in from the start. It is also worth thinking about how you will let fresh air in on warmer days, particularly for a gym or a busy salon.

What you will use it for

Different uses need different things. A home office needs a steady, comfortable temperature for long spells at a desk. A treatment room needs to feel warm for clients lying still. A gym needs fresh air. Telling us how you will use the room helps shape the design around you.

Comfortable for every kind of garden room

  • Home offices. A quiet, comfortable and professional workspace where you can focus and get more done. See our garden offices page.
  • Hair and beauty salons and treatment rooms. A stylish private space where clients feel comfortable whatever the weather.
  • Dog grooming rooms. A comfortable room for you and for the dogs, all year round.
  • Home gyms. Somewhere you will still want to train on a cold, dark morning. See our garden gyms page.
  • Studios and hobby rooms. A room for the things you love, not just a summer space.

A garden room, not a summerhouse

A building without insulation follows the weather outside, which is fine for storing tools or sitting in on a sunny afternoon. A garden room built with modern insulation is designed to be used all year, which is what turns it into extra space for work, business or relaxation.

Frequently asked questions

Can I use a garden room in winter? Yes. Our garden rooms have modern insulation and are designed to be comfortable all year round.

How will I heat my garden room? Power and heating needs are discussed at the quote stage, so they are planned in before the build starts.

Can a garden room be used for a business all year? A garden room can be a comfortable space for a salon, a treatment room or a grooming business all year round. Check with Sunderland City Council whether your business plans need permission.

Do I need planning permission for a garden room? It depends on the size, height and position of the room and what you will use it for, so there is no single answer that fits every garden. Check with Sunderland City Council or the Planning Portal before you commit to a design.
