Step 1 of 7

What are you looking to convert?

This determines the scope and structure of the estimate.

Step 2 of 7

What type of loft conversion?

If you're unsure, we'll advise at survey.

Step 2 of 5

What size is your garage?

Size is the main driver of cost in a garage conversion.

Step 3 of 7

What's the head height in your loft?

Stand in the middle of your loft and reach up. This is the most important factor in viability.

Honest note on low head height: A ridge height under 2.0m makes a full conversion very difficult and sometimes impossible without a roof lift. However, modern PIR insulation techniques can recover 40–50mm of usable headroom compared to older methods — which sometimes makes the difference. The only way to know for certain is a proper survey. We will always tell you honestly if your loft isn't viable.
Step 3 of 5

Will you need a bathroom or en-suite?

Adding plumbing is one of the bigger cost variables in a garage conversion.

Step 4 of 7

What type of roof do you have?

Look at your roof from outside. Most Essex semis have hipped roofs — sloping on all four sides.

Step 4 of 5

Where is your property?

We cover South Essex and East London. This helps us confirm we serve your area.

Step 5 of 7

Do you want an en-suite bathroom?

Adding plumbing and a wet room adds to the cost but significantly improves the space.

Step 6 of 7

What's included in your finish?

Our workmanship standard is the same across all projects — this is about the scope of what we complete for you.

Step 7 of 7

Where is your property?
