Loft Conversions
in Dorset & Hampshire
Turn your unused loft space into valuable living space with our local team, who guide you through every step.

Loft Conversion Services
A loft conversion is one of the best ways to add another bedroom or bathroom to your home, without sacrificing garden or outside space.
We handle loft conversions and dormer conversions across Dorset and Hampshire. From the very beginning of your project, you’ll work with our small specialist team. You will meet Fraser and Joe, who guide the build, giving your loft conversion the skills and focus it deserves.
Why Opt for a Loft Conversion?
Loft conversions are the ideal solution if you want an additional bedroom or bathroom, but don’t have, or want to use, garden space for an extension. The service is most popular for bungalow owners, where the loft space is going to waste as unusable storage. The best part? On a full conversion, you get a brand new roof as part of the service.

Loft Conversions We Offer

Loft Conversion
Hip-to-Gable Conversions
Suitable for properties where the roof slopes inwards at the side of the house (a hipped end). We build the slope into a vertical gable wall, squaring off the loft and allowing you to make full use of the width.
Mansard Conversions
Mansard conversions usually involve a full roof rebuild. We replace the existing structure with near-vertical walls and a near-flat roof above. This conversion maximises floor space and head height, but it’s a big job, and usually requires planning permission.
Dormer Conversion
Dormer conversions are the most common conversion. Part of the existing roof is removed to build a vertical wall up through the roofline, creating extra space and headroom where the roof would otherwise slope down. Dormer conversions are usually finished in cladding.
Velux & Rooflight Conversions
The most budget-friendly option. We fit rooflight windows into the existing roof slope, making no structural changes to the roofline. The outside of the house looks much the same, but this only works if you already have around 2.5m of head height in the loft.
Kitchen Extensions & Kitchen Remodelling
Kitchens so often do the heavy lifting in any home, and their role varies significantly from person to person. We build kitchens that look great and work exactly as you need them to, whether that’s a space for hosting and family moments, or a setup purpose-built for your cooking and routine.
L-Shaped Dormer Conversions
This conversion joins two dormers into one, combining the rear dormer with the side return (a layout that you find on many Victorian and Edwardian terraces. It creates much more floor space than a standard dormer, and often allows for a second room or en-suite. Always requires planning permission.

What Does a Loft Conversion Involve?
There are many specific types of loft conversion, but they usually fall into full conversions or dormer (partial) conversions. Here’s how the process usually works:
Full Loft Conversion
In a full loft conversion, the roof comes off completely. We install new ceiling joists, roof rafters and electrics. If you’re also fitting a bathroom, we then install the plumbing. After this, we finish the interior with insulation, plastering and painting. When completed, you will have fully finished rooms and a brand-new roof over the house.
Dormer Conversion
Dormer conversions are a smaller-scale option, stripping back only the section of the roof where the dormers are going, rather than the whole roof. If your property is compatible, this is a great middle-ground option, giving you additional space without the cost of a full loft conversion.
How We Work - Loft Conversions with ER Build Co.
In the initial site visit, we get a feel for your ideas.
We take a look at the existing property, assess the practicality of the work, check whether planning permission is required, and discuss timelines.
For loft conversions, you always need a structural engineer and technical drawings. We can connect you with a local architect and structural engineer to support you in this process.
Once relevant permissions are granted and we have the necessary structural plans and technical drawings, we agree your formal quote and get started on the build.

Free Consultation & Ballpark Quote
Every project starts with Fraser and Joe visiting your property for a consultation and site check.
Architectural Design & Planning Permission
Loft conversions do not always fall under permitted development and you may need planning permission. We will be able to assess where your property stands after the site visit, or we can work from your existing plans if they are already available.
Build & Completion
Once the relevant permissions are acquired, we begin the build, using scaffolding throughout, and doing everything we can to keep disruptions in your home to a minimum.
How Much Does a Loft Conversion Cost?
The cost of the project varies based on the scope of the work and the type of service required, such as loft conversion or dormer conversion, whether electrics and plumbing are required, and the size of the space.
Price is the way that we work very differently from others in our industry. We’ve noticed that many customers have previously struggled with unclear pricing - end costs varying from initial prices, surprise costs and late add-ons. We wanted to offer a price that our customers could trust, which is why we offer a price guarantee on every job. The price outlined in the initial quote is the price you pay.
Payments are never expected in a lump sum. We pace invoices across various stages of the build, pre-planned with you at the start of the project so you know exactly what you have to pay and when you are expected to pay it.

The Questions Most People Ask Us...
Can we stay in our house during the work?
While it’s easier if you do not need to stay at home, on nearly every loft conversion time you will be able to. We keep you updated throughout the process so you know what to expect. On the rare occasion that you won’t be able to stay at home, we will tell you at very beginning of your project.
Will the property be watertight while under renovation?
Yes, we make sure that the property is watertight throughout the entire build process. We use a temporary roof scaffold (tin hat) to keep your property protected and dry. By the time windows are in, you will no longer need the overhead scaffolding, as the weather stops playing a factor in the build.
How much noise will there be?
There’s no getting away from the fact that loft conversions can be noisy, however, we’re aware of it from the beginning of the build, and do everything we can to keep noise and disruption to a minimum.
Where will the staircase go, and will I lose space to fit it in?
This question is best answered after a site visit. In some cases, adding the staircase involves losing space in another room. We will be able to talk you through options in your consultation.
What is your experience with loft conversions?
Between us, we've got 19 years of hands-on trade experience, with Fraser's established roofing business and Joe's 10 years specifically in loft conversions and building work. We're a small team by choice, because it means you deal directly with the people doing the work, making you more comfortable throughout the build and confident in the standard you'll receive.
