Piggy Back Loft Conversion

Our clients had a great house in Kingston with an unused loft space, so they wanted to add a room or two with great views over the garden. But the height of the existing loft was too low for a normal loft conversion. So an unusual loft conversion design was needed.

To solve this we came up with an architectural design to raise the height of the roof, over the back part of the house. This is often called a ‘piggy back’ loft conversion or extension.

Kingston upon Thames Planning Approval

Planning Permission to raise the height of a roof can be difficult. But our design retained the original roof height at the front and raised it over the back of the house. This gave the space for a loft conversion, and also met the planning policy.

We won planning approval for the new loft design and roof height from Kingston Upon Thames first go. The result is a loft conversion with great space and light, and an amazing view from the new room!

Kingston Conversion and Roof Extension

A good loft conversion design can add a lot of value to a house. In a part of London like Kingston Upon Thames the added value per m² is far more than the build cost. So once the drawings were complete, our clients were very happy to get Planning Permission from Kingston for the work.

Loft Extension Planning Drawings

We planned how the loft conversion would be built in our design drawings. We put a temporary ceiling in on the first floor, so that our clients could stay in the house. Planning how this would work on the drawings was key. The ceilings and loft floor could then be removed and replaced with an upgraded structural floor.

Finally the ‘piggy back’ part of the loft conversion was formed using steel portal frames. These were tied together with a steel ridge beam. The loft design includes big sliding glass doors and frameless balustrade in the large gable end that look over the garden.

Loft Conversion Bedrooms and Bathroom

As well as a large new loft room at the back of the house, our architectural design adds a big loft bathroom and a small room for the family’s au pair at the front of the house. The three new loft rooms are connected by a bright landing space, with an oak stair and a glass balustrade. While the landing area is fitted with bespoke designed plywood joinery providing eaves storage. We did detailed architectural drawings for the loft conversion including the interior design.

Loft Conversion Design Glass Gable End

The architectural design of the loft room has a real wow factor because of the full height glass wall to the rear. This gives a stunning view over the park at the rear of the house. The glass slides opens so that in the summer the room is full of fresh air. Our clients use the space as somewhere to sit and write, or relax and read with the backdrop of the garden below.

The loft room is a bright space with lots of natural day light. Three large electric roof lights with blinds on the south roof pitch give even more control over the light in the space. At night high spec LED lights can be dimmed and set up to give mood lighting.

Glass, Roof Lights and Joinery

The same high spec roof lights and LED lights have been used in the design of the landing and front loft room. The space is well planned, and great architectural design details complete the loft conversion. These include frame less doors with flush hinges, oak handrails to the stairs, also bespoke joinery in a ply wood finish.
