Velux Loft Conversions


Loft Conversion with Velux Windows.

We can add a superb bedroom to your house within 6 weeks. To enjoy extra living space at a very competitive price, call us today and arrange a free, no obligation quote.

Our Velux type loft conversion requires no significant structural alteration to the roof or roof line. Velux windows in the roof provide natural light, we maximise room height and use space saving stair designs. All work meets or exceeds strict Building Regulations standards.

Because this loft style is less complex than dormer lofts a key advantage is an extra bedroom, living room or office can be added more economically and quickly. The planning and development time is measured in weeks rather than months so you can rapidly enjoy more space and add value to your home.

Rarely is Planning Permission required. Your Local Building Control office is the authority that approves our building plans and inspects our work and certifies your completed loft. So you can be sure it is completed to the highest standards, safe and comfortable to use.

Our considerable experience allows us to find the best loft design for your house within regulations and accurately cost the work and materials.

Our many clients in Hampshire, Surrey and West Sussex region use lofts built to many styles, efficiently and at competitive prices.

Our processes and friendly, qualified trades people maintain the highest standards as a conversion progresses through the following stages:

  • Free initial survey acceptance of our fixed price quote
  • Detailed survey
  • Velux Skylight window(s)
  • New floor structure
  • Fixed stairs and door
  • Timber frames
  • Lighting, power and heating
  • Insulation
  • Boarding and plastering

Your loft will then be ready to decorate and use and will have our 5 year structural guarantee.

Free Initial Survey and Quote

Based on our initial survey of the first floor and loft, and the design discussions we provide a written, no-obligation fixed price quote. This includes plans, materials and labour. The main other costs you will have is Building Control plans approval and inspection which ensures our work is compliant with building regulations.

Velux Skylight Windows

Velux create many window styles and sizes, even modular systems that combine windows into a bank for an intriguing and exciting display.

We always provide professional advice on the best positioning of windows for natural light into the room. We can also design for stunning effects such as those in our examples.

New Floor Structure

A strong, level floor is always required and installed so it has minimum impact on internal loft height.

Fixed Stairs and Door

Loft rooms need a fixed staircase and this needs to be well built. We always seek ways to minimise the impact of the stairs on the existing house and within the loft room. Our architectural surveyor will generally find and discuss with you the most space efficient method for installing a staircase into your existing house structure. This leaves more space within the loft and below.

We will also measure your loft to ensure there is adequate head height from the stairs into the loft.

Fire regulations also require a fire door for safety. Adding a third storey to a house will require certain other key doors to be upgraded too.

Timber Frames

The key skill when converting a loft is joinery. Generally the existing rafters need more depth to accommodate insulation, knee walls are needed for storage and a door frame is required.

Velux conversions in Victorian terraced and semi detached houses often have a party wall and this needs a frame to hold insulation and boarding.

Lighting, Power and Heating

We will assess your existing power supply and central heating system for suitability, and how to connect the loft with least disruption.

Recessed down lights are a typical choice of lighting system as they have minimal impact on head height, are controllable (dimmable) available in many styles are suitable for many bulb types. Lights and switches are also added to the stairwell.

We always discuss with clients the number and position of power sockets.


For comfort, economy and safety loft rooms are extremely well insulated. Deep insulation is positioned within the floor, walls and ceiling to keep cold and excessive heat out and warm air in. Building regulations specify insulation standards to be met.

Boarding and Plastering

Your loft must feel like a pleasant room to use and the quality of the finish depends on the accuracy of earlier structural work. Our professional plasterers add the finishing touches which make your loft look fabulous, professional and inspiring.


Final Building Control certification adds value to your home, but a bonus is that while the loft has added space, your rateable band will not change until you sell your house. Another reason to move up, rather than out.
