  • A lucas construction surveyor visits you to discuss design options for your home and the relevant planning and building regulations requirements. We provide a comprehensive quotation and we can also arrange for you to view a similar project, to give you an opportunity to see the standard of work and to help you realise the potential for your own home.
  • On placing of an order, a small deposit will be taken. Payments are only taken in arrears of work, and therefore no further payments are required until work has begun. a detailed survey and further discussions with you will be undertaken by our surveyor and structural engineer,they will draw up the relevant architectural plans. Plans will be send to you for your approval,any changes, alterations will be made free of charge. It normally takes around 2-4 weeks to draw up the plans and to get them registered with the local council. It takes approximately 8 weeks for the council to decide the application. Payments are only taken in arrears of work, and therefore no further payments are required until work has begun.
  • During the planning application period you are required to serve party wall notice(s) on your neighbour(s), to which they must consent prior to the commencement of the work. We will put you in touch with a party wall surveyor who will supply you with the notice(s) free of charge. We strongly recommend you serve these notices at your earliest opportunity in order to ensure works starts promptly after planning consent has been obtained.
  • The week before work commences, you will have a “pre-start” meeting with your project manager and the site foreman. the site foreman will be managing the team constructing your development. this meeting is an opportunity to fine-tune any details of your impending project. The site foreman will run you through the build process, explaining how they intend to tackle the project, the best channels of communication and how they will protect your home and minimise disruption to your family.
  • A few weeks before the build starts, Lucas Construction will apply for building regualtions on your behalf. Once planning approval has been obtained construction normally commences within 2-4 weeks.
  • The building team arrive on the agreed start date and construction begins. Prior to this, preparation of the site along with the protection of key areas will have already taken place; skips will have been delivered and scaffolding erected where appropriate.
  • During the construction stage of your project, one of Lucas Construction site consultants, or your designated project manager, will be visiting your site 2-3 times a week to ensure works are progressing according to the schedule.
  • You can expect construction work to last approximately; 6-7 weeks for a loft, 8-12 weeks for an extension. Upon completion of your project you will receive a 10 year structure guarantee, your building regualtions certifcate, a copy of your planning approval and most importantly some precious space!

From architectural plans and design, planning permission applications  (if required) and building regulations, we will handle the entire process. “However if you have all in place and would like us to handle only construction works we more than happy to take your project on board”. Our project managers will be  available to answer any questions and deal with any problems and will keep you  appraised throughout the entire process from start to finish. Upon completion of your project you will receive a guarantee for the works, your building regualtions certifcate, a copy of your planning approval and most importantly new pretty space!

Loft Conversions a vary considerably depending on the property, and in most cases a loft  conversion is entirely possible. We will advise you of the possibilities available to you in  consideration of your requirements and talk through all your options.

Here is a brief description of the usual types of Loft Conversions that we build for our customers.

Loft Conversions Types

Velux Loft Conversion

The simplest and most cost-effective loft conversion is to install Velux windows without making any changes to your roofline.  It works best when there is


ample headroom throughout your loft so you can make full use of all the available floor space. A Velux loft conversion requires considerably less construction work than a dormer or other types of conversion.  You can add an extra bedroom, living room or office quickly – and start enjoying your new conversion within weeks. With this simple type of conversion you don’t usually need planning permission, although there is an exception if you are in a conservation area regarding placement of velux windows.





Dormer Loft Conversions

A dormer is the most common type of loft conversion The types of possible Dormer loft conversions range from rear, front and side dormers.
Dormers can often be constructed without requiring planning permission and are often suitable for semi-detached and terraced houses.
The size of the Dormer can vary if it needs to remain in keeping with the property and where a flat roof is not acceptable to the aesthetics of the house. Since new regulations were introduced in 2008, many Local Authorities allow dormers to be built without planning permission providing the design is within guidelines. This has reduced the cost and speeded up the process.  But even if your dormer conversion design does require a planning application then Lucas Construction will submit all relevant paperwork.

There are few different styles of dormer loft conversions:

A flat roof dormer conversion














Cottage or pitched dormer conversion

(Sometimes called dog house dormers)
Cottage dormers can have a pitched roof and can be designed to fit all house styles. They allow you to have large windows or even French doors installed so light floods in.
Cottage dormer loft conversions are usually situated at the front of your property, though smaller and more traditional cottage dormers can be found at the back of some buildings.











Side dormer – Hip End loft conversion














Hip to Gable loft conversion

A hip to gable conversion involves making fairly major changes to the roof. The gable wall is built up to the ridge line and a new section of roof is built to fill in the gap. As a general rule, houses with hip roofs tend to not have enough internal volume for a conversion to be practical so a hip to gable conversion is the best solution.A new gable wall will be built either in masonry or studwork. There are several options for the finishing of the masonry gable wall, which include brickwork, blockwork with render or tiled. If the gable wall is built from studwork they are normally finished in render or tiled. For most people the preference of for the new gable wall to match the exisiting walls as much as possible. As a hip to gable conversion changes the outline of the roof planning permission may be required.We will need to determine if the conversion falls within permitted development allowance or need planning permission.But don’t worries either way can be done. Once the roof has been extended the conversion is normally completed with either velux rooflights or a dormer.










 Mansard Loft Conversion

A mansard roof has two slopes, the lower slope is close to vertical at 72 degrees and the top section of the roof is almost horizontal. This style of roof is named after a 17th-century French architect Francois Mansart (1598-1666) who used this design of roof on many of his buildings. A mansard roof has the advantage of maximising the available space within your loft.
Mansards are commonly built by raising the party/gable walls either side of your house to make the profile for the mansard and then creating the timber frame.. A mansard loft conversion will almost certainly require planning permission.

















L-shaped Loft Conversion

L-Shaped loft conversions can look spectacular and this is often considered as the best way to extend a mid terrace period proporty to maximize space. The box dormer or mansard is complemented with an additional extension over the rear roof. Ideal for a master-suite and a separate bathroom or Study Room. In most cases this generally falls under Permitted Development, although planning permission may be required.1roof37

“Friendly staff and an excellent service,


My first builder walked off the job leaving my house in ruins and my faith in the building trade shattered. Lucas and his team restored both with their friendly competent and reliable work. I was consulted at each stage and included in all the major design decisions. When what I wanted was not possible Lucas would explain why and offer an alternative which was often an improvement on my original idea.


It was great that you regularly asked us whether we were happy with the work and took prompt action if there was anything we were concerned about. We were surprised when the extension was finished within the timescale you originally gave us (three weeks) and this was purely down to your hard work


“From start to finish Lucas was on hand to ensure everything was completed to the highest standard, on time and within budget. All our costs were detailed on a weekly spreadsheet so we could see exactly what we were spending and there were no hidden surprises at the end of the job.”
