Crystal Palace Norwood SE19, Loft Conversion and Extension

L-shape dormer loft conversion and side return ground floor extension

‘L’ Shaped Dormer in Terraced House:

The client’s brief was to create a music room to house the Clients extensive vinyl record collection together with an additional room to be used as a home office. A new WC and shower room was also to be installed.

Side return ground floor extension:

The client had lived in the property for over 20 years and the kitchen / ground floor area was (in their words) tired and need of a little TLC. The existing ‘music room’ had been partitioned off from part of the existing kitchen. By constructing a side return extension the full length of the back addition (approx. 5.8m long) and demolishing the flank (side) wall of the property a new open plan kitchen / dining area could be created.

Loft Conversion:

Construction of an L-shape dormer was the obvious solution with the record collection housed in the larger room in the main loft void and the home office in the room built over the back addition. Absolute Lofts had already completed three other projects in the same road so the Client was able to view prior to construction and get a good idea of the floor plan and space created.

Permission to build:

All works were completed under permitted development guidelines. Absolute Lofts prepared all plans, structural calculations, building regulations application and Certificate of Lawfulness approval.


The work had to be completed with the Client living within the property whilst the work was completed as their budget did not extend to them renting alternative accommodation during the construction phase.

Special Requirements:

The project had to be phased so that the loft conversion was 90% completed and the Client could utilise the top floor as living accommodation whilst the ground floor extension was constructed.

The record collection had to be protected (for both security and ingress of dust) for the duration of the build together with the Clients extensive contemporary art collection.


Absolute Lofts completed the project (for both loft and extension) within approximately 18 weeks.

Client’s Comments:

“We were very specific with all potential Contractors that we wanted one Company (and preferably one team of builders) to carry out all the works. We also wanted one Company to handle all of the design and build from concept to completion. We interviewed three companies and it was clear that Absolute could offer the ‘one stop shop’ that we were after.

Both the loft conversion and extension came along great and was finished pretty much on schedule and budget (we spent more on kitchen units and floor tiling than we originally planned).”

The Disruption of a Loft Conversion

During the process of having a loft conversion, there is often the worry of it causing lots of disruption. There should be a little disruption expected, as there is with any construction project, however, we always like to prepare our customers so they know when they can expect this.

Builders will be on-site daily, but the first half of the loft conversion will take place outside with builders accessing the property via scaffolding. This means that the house will not typically be disturbed internally until it comes to the second part of the project when the new staircase needs to be installed. (more…)

Extra Costs to Budget for with a Loft Conversion

After budgeting the initial construction costs of a loft conversion, there are a number of other costs you should be aware of as you may also need to budget for these as well.

Building Control Fee – £650 + VAT

The Building Control Fees are charged when plans are submitted to the Building Control Company. They will check over the working drawings and check the structural calculations and design. Once the work commences they visit the property throughout the build at key points. Once the structure is built, when the insulation has been installed, the staircase has been installed to name a few. When the Job is completed they visit the property a do what is known as a final inspection and, if everything meets their requirements, a Final Certificate is issued for your records. The fee is paid by the client directly to the nominated Building Control Company. (more…)

Certificate of Lawfulness for a Loft Conversion

If you are considering having work done to your house, such as a loft conversion, there is specific documentation you can apply for that can prove any pre-existing/proposed development has been done lawfully. This is where a Certificate of Lawfulness comes in. (more…)

Are Modular Lofts Better Than Traditional Loft Conversions?

As a cost-effective way to increase living space and add value to a house, many people are choosing to convert their loft area. It can add up to 20% to the value of a property if done properly, so you can understand why many families are choosing to go down this route to create more room and add value to their home.

One of the first considerations to make when choosing to convert your loft space would be to decide on what type of loft conversion would be best suited for the project. With both modular lofts and traditional lofts being two options for a loft conversion, there are a few considerations to make. (more…)

Lowering ceilings to achieve a Loft Conversion

When considering having a loft conversion to your home, the first thing to establish is if the existing height within your roof is tall enough. The general rule of thumb measurement is 2.2m from the top of the existing joists to the underside of the ridge (the point in the middle). (more…)

GRP Roofing vs Three Layer Felt System

The majority of all loft conversions will have a flat roof constructed to them. The covering which makes them water tight can be achieved using various products, with 2 standing out as the industries norm. The first being a 3 layer felt systems and second GRP (glass reinforced plastic). (more…)

Wooden Windows & Doors VS UPVC

This is a common question asked when placing an order for a loft conversion. We can only share our many years of experience on the use of both these products. Whilst wooden French doors may look more in keeping with your house, they have fundamental flaws which do not lend themselves to being a good choice for a loft conversion. (more…)
