Acton is both historic and modern; it is exemplary of idyllic West London residency. It is a sophisticated neighbourhood characterised by Tudor inns and the link between London and Oxford. A home in Acton is a lucrative prospect with convenience and offers peaceful living within city limits. So, let’s start by making sure you can continue to enjoy the luxuries of Acton life, even when you run out of space in your house. The added advantage of a new space completes the cosy appeal of your home. Loft conversions Acton can make room for your growing family or for yourself, to live an unhindered life.

Loft conversions are almost always straightforward. If planning permission is not a requirement, the project can start as soon as your property’s suitability gets assessed. Good Design & Build offers a free consultation to help you get started and determine how your Acton loft can afford you the extra space it is hiding.

The essential element is 2.2m of head height, which is the distance from the highest part of the loft roof to the loft floor. A roof pitch of 30 degrees allows for comfortable head height, and as the pitch angle rises, the head height increases. There should also be room on the first floor to fit in the new staircase to access the loft space. You will also need an assessment by a structural engineer to make sure the floor and the roof are not in any danger of damage or collapse due to building work.

Loft conversions are permitted developments that often do not require planning permission. However, there are particular circumstances, such as living in a conservation area or a listed building that changes this. So, it is always safe to find out the designation your area or the building you live in, holds. Do not be discouraged by the need for permission; it is a task Good Design and Build takes up on your behalf. We submit all applications for conversion in Acton. Semi-detached and terraced homeowners have to get the neighbours on board the conversion plans with Party Wall Agreements.

If you are looking to increase head height and floor space with uncomplicated construction, then a dormer loft conversion ticks the boxes, literally. These box-shaped additions rise out of a pitched roof and are a familiar sight due to their popularity.

To simply transform your loft into a room without heavy building work, Rooflight conversion comes handy. It is the simplest and cheapest type of loft conversion.

If better aesthetics and a bigger space are what you are going for, a mansard conversion can achieve both. Although more expensive, it gives you the best of both worlds.

Hip to Gable is suitable for semi-detached and detached homes that have a hipped roof. It is a strong contender for 1930s homes, which are the most common hipped roof properties in the UK.

Velux loft conversion or Rooflight conversion costs £20,000 upwards.

The Dormer loft conversion can start from £30,000.

A Hip to Gable loft conversion costs between £40,000 and £50,000.

A Mansard loft conversion can range between £45,000 and £65,000.

Costs can vary depending on the floor area, design features, and structural changes. Good Design & Build offers all quotes in square metres for a fully transparent pricing system.

When it comes to loft conversions, we have years of experience providing the best quality transformations for everyone’s tastes. We offer free no-obligation quotes and two separate contracts for Design and Build phases, so opting out of one without moving on to the other is an actual option.

Make your loft conversion a design masterpiece with Good Design & Build architecture team.

How we deliver projects

Our process is simple and divided into two distinct phases with separate contracts: Design and Build. As a client you only commit to one phase at a time depending on what stage of the process you are in. Each phase consists of three stages as described below.

1. Design

This is the kick-off point for your project. We carry out a complete architectural measured survey of the property. This allows us to create accurate CAD design drawings. This is followed by a design meeting to start discussing your ideas in more detail.

2. Planning

At this stage we finalise the designs with you and start preparing planning applications as needed. We place a high priority on ensuring that plans, designs and schedules are all based on a thorough and detailed understanding of planning guidelines. We co-ordinate with local authorities until the decision is made, and the planning approval is secured.

3. Technical

Once the planning consent is secured, we translate the design drawings into more detailed technical drawings for the purposes of building control and construction. This also includes specifications and structural calculations. At this stage, we will also submit to you our ‘no obligation’ quote for the build phase.

4. Pre-build

90% of our clients decide to stick with us after the design phase is completed. Once the build contract is signed, we kick off the process by making sure all the pre-build processes are complete. These include assistance with party wall agreements, Thames Water build over agreement, submitting building control application, and preparing method statements etc as needed. This stage ends with a pre-start meeting with your foreman before the actual build begins.

5. Build

One of our foremen will be dedicated to your project and will be on-site to manage everyday works. Our project managers will be overseeing the works to make sure they are completed to high standards, within your budget and on time. Throughout the process we will keep you updated with the progress and coordinate the works with third parties such as kitchen or flooring suppliers. We will also advise and guide you to choose any suppliers if needed.

6. Handover

As the build draws to finish, we will help to iron out any ‘snags’ to make sure everything is completed to your satisfaction. We will put together all necessary certificates such as gas, electricity and building control completion along with warranties for glazing, boiler etc. At the final completion meeting, we will hand you these documents, together with the keys to your house. Needless to say, you can contact us any time after this, if you want us to look at something.
