Project Description

Location: Wellington St Johns Wood NW1
Type of Project: House Renovation, Remodelling, Extensions, Loft Conversion
Architect: APT Renovation

This particular client requested that we give their St Johns Wood property a full renovation and remodelling in terms of design and structure. They also wanted to increase the space with a loft conversion and extensions.

The Challenges

Our team managed to completely transform the interior design in this property to a more sophisticated and modern finish. In the lounge area, we opted for light, pastel colours, large windows, bespoke mirrored cupboards and state of the art lighting. For the flooring, we used gorgeous beech wood in most living areas.

We also completely revamped the staircase and fitted ceiling lights in most rooms. In the kitchen area, we installed mirrors to create the effect of a larger space and fitted the flooring with marble tiles.

Our joinery created lovely bespoke kitchen units and fittings throughout the property, in a range of different colours and uniquely designed styles. We carried out a basement conversion and turned it into a fabulous entertainment room, creating a really cosy vibe, complete with corner sofas and wooden walls and adjustable lighting.

A loft conversion also took place to create homely bedrooms with skylights.

Dormer Loft Conversions

If you live in Chelsea and looking for a dormer loft conversion is a structural extension that projects vertically from the plane of a sloping roof. By building a dormer onto an existing roof, a cramped attic can be transformed into a usable space thanks to the creation of additional headroom and floor space, with natural light coming in from the dormer windows.

The most popular type of dormer conversion in the UK is a simple flat roof dormer. As well as being the cheapest form of the dormer to build, a flat roof dormer also offers the largest amount of additional internal space. A shed dormer also features a flat single planed roof but sloped downwards at an angle shallower than the main roof. Often used on homes with a gable roof, a shed dormer usually requires different roof sheeting to that of the main roof.

A gable-fronted dormer or “dog-house dormer” is a more attractive option that consists of a gable wall extension built up to the existing ridgeline, and a new roof section built outwards to the new gable end. Similarly, a hipped roof dormer is an aesthetically pleasing option featuring three sloping planes of a hipped roof converging at the ridge of the dormer.

Mansard Loft Conversions

All You Need to Know

Mansard loft conversions often require more construction work than other types of loft conversions but can result in creating a significantly larger living space in your home, regardless of property type. Here, we provide answers to some of the most commonly asked questions about mansard loft conversions.

Is Planning Permission Required for Mansard Loft Conversions?

Planning permission is almost always required for this type of extension. These conversions create maximum living space within your roof by effectively creating another storey to your property. As this results in changes to the roof shape and structure, it is highly likely that planning permission will be needed from your local authority.

What Types of Houses are Best for Mansard Conversions?

Mansard roofs are particularly common in London and other urban areas and can often be seen across whole rows of older terraced properties. Although not regularly seen in suburban areas – flat roof dormers are typically cheaper and simpler to construct – mansard roofs are actually suitable for almost all types of properties. Detached, semi-detached and terraced houses, as well as chalets and bungalows, can all typically house mansard loft conversions.

In terms of aesthetics, the external walls of a mansard extension can be exposed brickwork, rendered or clad with slate or tile whichever best fits with your property.

Hip to Gable Loft Conversions

All You Need to Know
Hip to gable loft conversions is becoming an increasingly popular way to create extra room in a property. But before committing to extending your home with this type of loft conversion, there are a number of things you need to know. Here, we take a look at what hip to gable loft conversions actually are, any limitations or restrictions you might need to consider, and also how to calculate the volume of these loft extensions.

What is a hip to gable loft conversion?
Most properties have a regular, ‘hipped’ roof with a sloping side. This means existing loft spaces are often limited, making it difficult to create a loft conversion without extending your property. This is where hip to gable loft extensions come in.
This type of loft conversion extends your property on the sloping side, effectively replacing the sloping roof with a vertical wall (the gable) at the end to the same height as the ridge, and filling space in between. The added space can then be used for whatever purpose you see fit, although typically it’s big enough for an office, play area or additional lounge space.
If your property has two sloping sides and you replace them both with vertical walls, it will be a double hip to gable loft conversion and will obviously provide you with even more additional space.
