Why convert your loft?

It is easy to outgrow a house, whether a new baby arrives or the children reach their teens. A loft conversion usually takes less time than an extension, and in most cases it can go ahead without planning approval, provided some simple rules are followed. It also keeps your garden intact, which matters in built-up areas where outdoor space is limited.

A conversion can also add value. A two-bedroom home can become a three-bedroom home, and some owners rent out the extra room for additional income.

Types of loft conversion we build

There are four main types of loft conversion. Which one suits your home depends on the shape and height of your roof, whether the house is detached, semi-detached or terraced, your budget, and any local planning restrictions.

Dormer conversions are a specialism of ours. A dormer extends out from the slope of the roof, so it needs a sloped roof to start from, and it adds headroom and natural light to the new room. We handle every stage, from the first design to the finishing touches, and make sure the dormer sits well with the rest of your house.

Planned around you, with all trades in one team

Every conversion starts with careful planning. We take accurate measurements, talk through your ideas and learn how you would like to use the room, and we help you choose the architectural features. Whether you want a home theatre or an en-suite with a power shower, we can plan it in.

We take care of everything from start to finish, with all the trades your conversion needs in one team, which gives us full control over the whole project:

  • Plumbers
  • Tilers
  • Electricians
  • Flooring specialists
  • Carpenters

No loft to convert? Consider an extension

If your home has no loft space to convert but does have room outside, an extension can do the same job. A single-storey extension can enlarge your living room, dining room or kitchen, while a double-storey extension can add bedrooms and a larger family bathroom. We can apply for planning permission on your behalf. See our house extensions in Southampton.

Local to you

Loft conversions across Southampton and nearby

A lot of Southampton's housing is well suited to going up rather than out. Victorian and Edwardian terraces in Portswood and Shirley often have enough roof height for a rear dormer, and the city's interwar semis are classic candidates for a hip-to-gable conversion with a dormer behind. Outside conservation areas, many of these can go ahead under permitted development, which keeps things moving. Post-war homes with shallow, trussed roofs need a closer look before we recommend a loft.

Also covering

West End
Some West End homes are bungalows and chalet bungalows, where converting the roof space can add bedrooms upstairs without extending the footprint.
Bitterne
Bitterne's hipped-roof semis are ideal for a hip-to-gable conversion, which squares off the roof and gives a full-height room with a proper staircase.
Hedge End
Newer Hedge End houses often have trussed rafters and lower roof pitches, so we measure the head height and check the roof structure before quoting a loft.
Totton
In Totton we usually find post-war and modern roofs, where a rear dormer or a simple rooflight conversion is often the practical option.
Romsey
In Romsey's conservation area a loft conversion needs planning permission, and dormers that face the street are less likely to be approved than discreet rear ones.
New Forest
Loft conversions are not permitted development inside the New Forest National Park, so a planning application to the Park Authority is part of every loft job there.

A typical loft conversion project in Bassett, Southampton

Loft bedroom with exposed roof trussesLoft bedroom with a desk under the eaves
The home
Bassett has many detached houses with large hipped roofs, which often hide a generous amount of usable space.
What's usually wanted
Families often want an extra bedroom with an en-suite so they don't have to move as children grow.
How we'd approach it
We measure the head height and check the roof structure, then usually design a rear dormer or a hip-to-gable change to gain a full-height room. The new staircase is planned over the existing one so the first-floor layout loses as little space as possible.
The result
The house gains a quiet top-floor bedroom and bathroom without giving up any garden.

What our customers say

Built on recommendations.

Caws Carpentry have done an excellent job at opening up our wall and reinforcing it with steel. Ryan and his team were professional – on time, no problems.
GGary LangdownCustomer review
Caws Carpentry undertook a large extension with new roof, attic conversion and total refurbishment of the whole house over a period of 11 months. Caws Carpentry were well-organised with great attention to detail and kept us informed and consulted on changes to scope and cost. The quality of workmanship and finish was exceptional and we are so pleased with the result.
SSophie LiddellExtension, loft conversion & refurbishment
I thought this was a fairly straightforward job but as it progressed I realised there was more to it than I expected. In the end 3 different teams worked on it and I appreciated them each being experts in their own particular trade, rather than using someone who was more of a general carpenter/Builders. Each team was very efficient and did a superb job. Ryan was always available if needed and I was consulted on each stage of the project, and he took a lot of care to ensure the final design would stand the test of time. Highly recommend
