Loft conversion ROI calculator
Curious how a loft conversion could affect your home’s value? Enter its current value and an estimated conversion cost to see a projected future value, both with and without the conversion.
How it works
What the calculator shows
It compares two projections over the same period, using an estimated average annual property price growth rate of 4%.
Without a conversion
Your home’s current value, grown by 4% a year for the number of years you choose.
With a conversion
Your home’s current value plus the cost of the conversion, grown by the same 4% a year.
An illustration, not a valuation
Real growth and the value a conversion adds depend on your home, your area and the market.

Our process
How your loft conversion comes together
The same proven sequence on every project, from the first steel going in to the final sign-off, with you involved at the moments that matter.
- 01
Steel fabrication & structure
Work starts on day one with steel fabrication and the new structure, creating a strong framework to safely support your new living space.
- 02
Stair fitting
With the structure finished, we fit your new staircase so the loft is safe and easy to reach from the floor below.
- 03
Last-minute design
Once the stairs are in, you come up and see the space for yourself. Planning rooms and windows while standing in the loft is far easier than working from a drawing.
- 04
Plumbing & electrics
First-fix electrics and plumbing go in, and you can talk through ideas for your bathroom and main room with our electricians and plumbers.
- 05
Insulation & boarding
We insulate, plasterboard and build internal walls while our roofers and bricklayers work outside, keeping the time on site to a minimum.
- 06
Completion & sign-off
Plasterers, second-fix joiners, electricians and plumbers complete every detail on site, leaving you with a transformed home you’ll love for years to come.
