Your home, properly planned
Loft Conversions for the way you live
Start with the space you can actually use
A loft conversion can provide a bedroom, a workspace or another useful room without extending into the garden. However, the size of the loft floor does not tell you how much comfortable living space can be created. Headroom, roof pitch, structural timbers and the position of a new staircase all matter. Before deciding where a bed or desk will go, consider how someone reaches the room, stands up and moves around it.
This service suits homeowners who need more accommodation and have roof space worth investigating. It can also form part of a wider renovation where the upper floors need rethinking. A free site visit is the first opportunity to discuss the property and the room you want. Suitability still depends on appropriate design, structural assessment and the approvals required for the actual proposal; not every roof can be converted using the same approach.
Connect the new room to the existing house
A successful conversion should not make the floor below harder to use. Stair placement can affect a landing, an existing bedroom or storage. Fire-safety requirements can extend beyond the loft itself, so the route down through the house needs attention as well as the new roof-level room. Matt and his team manage the agreed project end-to-end, coordinating specialist trades and building control inspections and sign-offs rather than treating the conversion as a stand-alone decorating exercise.
Before the work begins
The problems worth resolving early
Avoid designing around an unverified roof
Existing ceiling joists should not be assumed to provide a suitable floor for habitable accommodation. Altering roof members without a structural design can put the building at risk. A conversion needs the correct support strategy and a considered sequence of work, including any temporary support. Do not cut timbers to gain headroom or begin an opening for stairs before the structure and design have been assessed.
Insufficient insulation, ventilation or moisture control can leave a roof room uncomfortable and vulnerable to condensation. A large window alone is not a complete summer-comfort strategy. Poorly planned stairs can also consume space elsewhere or create an awkward daily route. Resolve structure, access, fire safety and the roof envelope together; leaving these decisions until plastering can mean reopening completed work or changing a layout that no longer meets the project requirements.
From survey to handover
Our approach to your loft conversions project
01 · Free site visit and a practical brief
Discuss your aims with Matt and arrange a free, no-obligation site visit. The visit is used to understand the existing space, the work you are considering and the decisions that may need further investigation. It is not a promise that concealed conditions or every approval requirement can be settled immediately.
Share the intended room use, existing drawings if available and any previous changes to the roof. Think about where stairs might fit on the floor below. Tell Matt if you want a bathroom or need to remain at home, so these requirements are considered before a layout is settled.
02 · Assessment, design and an agreed scope
Establish the design information and specialist input required for your particular project before final construction decisions. Clarify any approval responsibilities, product supply and the work included in the quotation. Compare proposed options against your priorities and budget. If an item remains undecided, identify it clearly rather than assuming it is covered by a broad description of the service.
03 · Schedule, deposit and milestone payments
A schedule of works is issued with a payment plan, including an initial deposit and stage payments linked to the agreed work. Discuss access, deliveries, product decisions and essential facilities before the start. Where a change is needed, agree its effect on the scope, cost and programme before proceeding, so the shared plan remains clear.
04 · Managed construction and relevant checks
Matt and his team manage the agreed project from start to finish, coordinating specialist trades and building control inspections and sign-offs. The particular checks depend on the works and relevant requirements. Preparation, installation and verification should follow the agreed design and product specifications; important concealed details should be addressed at the appropriate stage rather than left until decoration is complete.
05 · Completion, handover and workmanship guarantee
Review the completed work against the agreed scope and discuss any points that require attention. Retain relevant product care information, certificates and inspection documentation applicable to the project. The build carries a 12-month workmanship guarantee, including certified specialist trade work. Ask about routine maintenance and how to raise a workmanship concern so the next step is clear after the team leaves.
Practical outcomes
What a considered project gives you
Additional accommodation without using the garden
A suitable loft can create space above the existing footprint, preserving outdoor areas for play, planting or relaxation. The benefit depends on how much of the roof becomes genuinely usable. Comparing layout options with furniture in place is more informative than counting the entire floor, including areas beneath low slopes that are best used for storage.
A room designed for comfort and access
Planning insulation, ventilation, lighting and stairs together helps the new accommodation function as part of the home. Position a desk where glare is manageable, allow circulation beside the bed and consider whether built-in storage under the eaves is accessible. Decisions about heating and controls should reflect the new room rather than simply copying another floor.
Coordinated work across several floors
A loft project may involve structural work, roof alterations, stairs, electrical work and changes along an escape route. Matt and his team coordinate the agreed trades and inspection stages. The schedule of works and milestone payment plan give you a clearer sequence, while the 12-month workmanship guarantee provides a defined commitment after completion rather than an unspecified lifetime promise.
Materials, methods & decisions
Planning the details of your loft conversions
Rooflight, dormer and larger roof alterations
A rooflight conversion may retain much of the existing roof profile, subject to suitability and relevant requirements. A dormer can change usable headroom and the shape of the room, but introduces new walls, roof junctions and external design considerations. Hip-to-gable or other larger roof changes require their own assessment. These are possible design approaches to discuss, not a promise that any one is permitted or appropriate at your property.
The choice should follow the proposed use and the building, rather than a preference for the largest possible addition. Consider the position of the staircase, views towards neighbours, storage beneath slopes and how much remaining roof space needs maintenance access. Planning permission, building regulations and any applicable neighbour-related procedures should be checked separately; an assumption about permitted development does not establish that a scheme is compliant.
Floors, insulation and moisture management
The new floor and any roof support must be designed for the intended loads. Structural beams and joists influence ceiling depth and room layout, so their positions need coordination with stairs and services. Insulation arrangement depends on the chosen construction and must work with ventilation and moisture control. Simply filling every available void with insulation is not a reliable substitute for a specified roof build-up.
Internal linings, roof coverings, windows and flashing details contribute to a weatherproof and comfortable room. Acoustic separation may matter if the loft becomes a bedroom above another sleeping area. Heating, electrical outlets and lighting should be positioned around usable wall areas; sloping ceilings can make standard placements unsuitable. If a bathroom is proposed, drainage routes and water supplies need assessment before fixtures are selected.
Stairs, fire safety and occupation during work
A staircase is a permanent part of the home, not simply a way to reach a converted attic. Its design must fit the available space and relevant requirements, while preserving useful circulation below. Fire-safety provisions need project-specific consideration of the escape route and existing arrangement. Ask how access, roof opening-up and internal work will be sequenced if you intend to remain in the house, including any temporary loss of a room or landing.

Questions before you start
How much do loft conversions cost in Epsom?
Roof form, usable headroom, structural support, the type of roof alteration, staircase position, insulation and any bathroom affect cost. Fire-safety work elsewhere in the house can also form part of the scope. A quotation needs to distinguish the habitable conversion from optional joinery and finishes. We do not publish a fixed price for an unseen property. Start with a free, no-obligation site visit and quotation so the proposed work, inclusions and outstanding decisions are clear before you commit.
How long will my loft conversions project take?
Design development, structural calculations, permissions where needed, stairs, roof windows and inspection stages can affect the sequence. Weather matters when opening the roof, while remaining in the house may require separation of work areas and staged access. Matt and his team issue a schedule of works for the agreed project. Discuss your preferred dates and any essential deadlines, but do not rely on a generic duration before the design, scope and relevant dependencies have been established.
What should I prepare for the free site visit?
Share the intended room use, existing drawings if available and any previous changes to the roof. Think about where stairs might fit on the floor below. Tell Matt if you want a bathroom or need to remain at home, so these requirements are considered before a layout is settled. The visit and quotation are free and carry no obligation to proceed. If you already have a designer or another professional involved, mention that so the available information and next decisions can be discussed together.
Will I need planning permission or building control?
Requirements depend on your property, the proposed works and any applicable site constraints. Planning permission and building regulations are separate matters; one does not replace the other. Check the route for your particular scheme with the relevant authority and advisers. Matt and his team coordinate building control inspections and sign-offs as part of managing the agreed project.
Who manages the work and specialist trades?
Matt and his team manage the project from start to finish, coordinating the agreed construction and specialist trades. Kitchen and bathroom projects involve specialist designers. Clarify the scope and any separate professional appointments before work starts, so responsibility for design, supply, installation and relevant approvals is understood rather than assumed.
What guarantee is included, and are you insured?
Matt Brash Builders Ltd is fully insured. The build carries a 12-month workmanship guarantee, including work completed by certified specialist trades. This is a workmanship commitment, not an unlimited product lifespan or a substitute for routine maintenance. Retain your project information and ask Matt how to raise a concern about the completed work.
How long should the results of loft conversions last?
Roof coverings, windows, flashings, ventilation and ongoing maintenance influence long-term performance. Keep roof drainage clear and investigate leaks or persistent condensation rather than covering them with decoration. The service life of individual products differs from the 12-month workmanship guarantee. Discuss the selected materials and care requirements during the project. The useful life of a construction element, fitting or finish depends on its specification, exposure and use, so we do not promise an unsupported number of years for the whole service.
Do you provide emergency or same-day work?
We focus on planned building work rather than emergency call-outs. Our hours are Monday–Friday, 8am–6pm. Call Matt to discuss planned work and current availability. If there is an immediate risk to people or the building, seek the appropriate urgent assistance rather than treating a future site visit as an emergency response.
Do you carry out loft conversions outside Epsom?
Matt Brash Builders Ltd is based in Epsom and also covers Ewell, Ashtead, Leatherhead, Chessington, Kingston upon Thames, Sutton, Cobham and Guildford. Discuss the property location and access when you call. The quotation and programme are based on the individual project rather than assuming every home in an area has the same building conditions.
How do I take the next step and agree payments?
Use the online enquiry form or call 07449 907407 to discuss a free site visit. Share your project outline and location so the next step can be discussed. Once the project is agreed, a schedule of works and payment plan sets out the initial deposit and milestone payments linked to the agreed work.
